When electronic equipment is powered on, the input capacitor inside a switching power supply requires a large amount of current to charge in a very short time. This sudden current spike is called inrush current. Although it only lasts for a short period, it can create stress on components such as fuses, bridge rectifiers, switches, relays, and power semiconductors.

When a switching power supply is turned on, a short but high current spike may occur before the system reaches normal operation. This phenomenon is known as startup inrush current. Although the duration is usually very short, the peak current can be several times higher than the rated operating current, creating stress on components such as fuses, bridge rectifiers, switches, relays, and power semiconductors.

AI servers generate concentrated heat inside high-density racks. GPUs, CPUs, memory modules, and power components may remain under heavy load for long periods, making temperature control a key part of system performance and reliability.

Air-conditioning systems depend on accurate temperature monitoring to maintain comfort, improve energy efficiency, and protect critical components. NTC thermistors are widely used in residential and commercial HVAC systems because of their compact size, fast response, stable performance, and cost-effective design.

AR glasses integrate processors, batteries, optical modules, and charging circuits into a compact wearable device. During operation, heat can accumulate quickly, affecting performance, battery safety, display stability, and wearing comfort. MF51 glass-encapsulated NTC thermistors provide compact, stable, and responsive temperature sensing for key thermal-management points in AR glasses.

Kitchen environments present unique challenges for fire detection. Steam, cooking fumes, and grease can easily trigger false alarms in conventional smoke detectors. As a result, heat detectors have become the preferred fire protection solution for kitchens and other environments where smoke detection is less suitable. The HTS-5 Precision Bracket-Type NTC Temperature Sensor is designed to provide fast, accurate, and reliable temperature monitoring for ceiling-mounted heat detectors, helping improve fire detection accuracy while minimizing false alarms.

Coffee machines operate in challenging environments characterized by high-temperature steam, repeated heating and cooling cycles, continuous pump vibration, and high humidity. These conditions place demanding requirements on temperature sensing components. Reliable temperature control not only affects coffee quality but also directly impacts equipment safety and service life. Designed for harsh operating conditions, MF51 ceramic-base glass-encapsulated NTC thermistors provide a stable and accurate temperature sensing solution for household, commercial, fully automatic, and capsule coffee machines.

In humanoid robots, large joint actuators drive key motion areas such as the shoulders, elbows, waist, hips, and knees. As robots become more dynamic, compact, and powerful, heat management inside these joints becomes increasingly critical. During jumping, sudden stops, rapid turns, or continuous operation, heat can build up quickly inside the actuator. If this heat is not monitored in time, it may lead to control drift, insulation aging, magnet demagnetization, lubrication failure, joint malfunction, or system shutdown.

In power supply systems, inrush current at startup is one of the key factors affecting equipment reliability. When power is applied, large capacitors charge rapidly, generating a surge current far exceeding the rated value. This transient current can damage rectifier bridges, electrolytic capacitors, and even input fuses. To ensure safe startup and extend system lifespan, inrush current limiter are widely used in power supplies and charging equipment. Their core function is to limit inrush current and protect critical components.

Another common concern is appearance: Why do identical NTC thermistors have different surface finishes? This difference is mainly related to the coating, not the sensing element itself.

High-power fiber laser welding equipment (20kW–30kW) is widely used in steel structures, power equipment, shipbuilding, rail transportation, and heavy machinery. While providing high efficiency and deep-penetration welding capabilities, the equipment generates a significant amount of heat during continuous high-load operation. Temperature control has become a critical factor affecting the safe and stable operation of the equipment.

Loop resistance testers are essential for evaluating electrical connection quality and system safety. Their accuracy directly impacts the reliability of test results. However, two key challenges often limit performance: · Temperature drift affecting measurement accuracy · Overheating under high current operation NTC thermistors provide an effective solution to both.

Commercial steam ovens demand sensors that can withstand high temperatures (up to 250°C/482°F) and saturated humidity. The MF58 series glass-encapsulated NTC from Shiheng Electronics provides a hermetic seal that prevents moisture ingress, ensuring: 1. Extreme Durability: High insulation resistance (500 MΩ) and dielectric strength (1500V) protect against short circuits in steaming modes. 2. Multimodal Stability: A wide operating range (-55°C to +250°C)/(-67°F to 482°F) allows one sensor to manage everything from low-temp fermentation to high-temp sterilization. 3. Rapid Response: A thermal time constant of ~12 seconds enables precise PID control, preventing temperature overshoot during rapid mode switching.

The primary difference lies in their environmental resilience and temperature limits: Epoxy-Coated NTCs are cost-effective and provide a fast thermal response, but are typically limited to 125°C and are sensitive to moisture. Glass-Encapsulated NTCs (like the MF58 series) offer a hermetic seal, making them waterproof and stable up to 250°C. "Bead-type" refers strictly to the physical shape (small and rounded) rather than the material; both epoxy and glass thermistors can be bead-type.

As residential solar energy systems become a global standard, the inverter has emerged as the critical "brain" of the installation—responsible for converting DC power from photovoltaic panels into usable AC electricity. In modern home energy ecosystems, inverter reliability is the primary driver of overall energy efficiency, system stability, and equipment longevity.

The core needs of car vacuum cleaners are "stable vacuuming" and "safety protection," and the working stability of its core component, the motor, directly determines the product experience and safety. NTC thermistors, relying on their "temperature-resistance" characteristics, play a crucial role in three major scenarios, avoiding the risk of motor failure throughout the process and ensuring user safety.

As e-cigarette devices evolve with higher power output, refined temperature control, and more stringent safety standards, temperature management has become a critical aspect of entire system design. Precise temperature monitoring not only affects the atomization effect but also directly relates to device safety and the lifespan of critical components.

In the era of Electric Vehicles (EVs) and intelligent climate control, a 1°C error in ambient temperature detection can lead to a 5% increase in HVAC energy consumption. For automotive engineers, the challenge isn't just measuring temperature, it's maintaining long-term stability in a high-vibration, corrosive, and thermally volatile environment.

As smart home products continue to evolve, automatic clothes drying racks have become far more than simple lifting systems. Today’s models integrate LED lighting, heating and drying functions, UV sterilization, obstacle detection, and even app or voice control. Behind this convenience and intelligence, however, lies a complex electronic system that must remain stable every time the device powers on. One small but critical component plays a key role in protecting that system:  Inrush current limiter MF72.

Temperature sensing is rarely the most visible part of an automotive system, but it often becomes the first thing engineers look at when something doesn’t behave as expected. In battery packs, onboard chargers, motors, and power modules, temperature data directly affects how control logic responds to stress conditions. That’s where automotive-grade NTC thermistors come in. What defines an automotive-grade NTC thermistor is not a single specification on a datasheet. In practice, it comes down to how the part behaves after years of heat, vibration, and repeated thermal cycling.

When selecting an NTC thermistor, resistance value, accuracy tolerance, or B constant are typically considered. While these parameters are important, the package type becomes equally crucial once the design enters the manufacturing stage. In practical applications, the package directly impacts reliability, ease of installation, and longterm performance.
