1.Main Product Types Shielded Molded Composite Power Inductors Integrated iron composite molding structure, ultra-high saturation current, low magnetic leakage, the mainstream choice for automotive ECU, T-box and ADAS power modules. Shielded Wire Wound Automotive Power Inductors Low DCR, low heating loss, stable inductance under continuous heavy load, suitable for medium-current vehicle power supply circuits. Unshielded Wire Wound Power Inductors Higher Isat, cost advantage, applied to large space power boards without strict EMI control requirements. High-Current Through-Hole Power Inductors Large wire diameter, strong overload capacity, used for new energy vehicle OBC, DC-DC high-power conversion modules. Low Profile Automotive Power Inductors Ultra-flat packaging, fit narrow installation space of instrument panels and on-board display power boards. 2.Core Technical Specifications Inductance Range: 0.1μH ~ 470μH Certification Standard: AEC-Q200 Grade 1 / Grade 2 Operating Temperature: -55℃ ~ +125℃ (automotive wide temperature range) Low DCR: Reduce power consumption and heat generation under long-term vehicle operation High Saturation Current (Isat): Resist inductance drop under instantaneous peak load of vehicle startup/acceleration Rated RMS Current (Irms): Stable continuous current output Vibration & Shock Resistance: Meet ISO automotive mechanical reliability test standards Magnetic Shield Option: Shielded / Unshielded for different EMI control demands Inductance Tolerance: ±10%, ±20% standard for power conversion 3.Core Advantages AEC-Q200 automotive certified, long service life matching vehicle full lifecycle requirements Stable electrical parameters under extreme cold and high temperature engine compartment environments Excellent mechanical shock & vibration resistance, no open circuit or parameter drift during bumpy driving High saturation characteristic, no performance degradation under vehicle instantaneous large current impact Shielded models greatly reduce magnetic radiation, avoid interference with adjacent vehicle signal circuits like radar and CAN bus Low heat generation design, adapt to confined heat dissipation space inside automotive control boxes Resist complex on-board EMI noise from ignition coils, drive motors and high-voltage lines Rich SMD low-profile and high-power through-hole series, compatible with all types of automotive PCB assembly 4.Typical Circuit Functions Energy storage and ripple filtering for on-board buck/boost DC-DC converters Current smoothing for automotive ECU, BMS, T-box and ADAS power supply rails Inrush current limiting to protect vehicle power management ICs LC power filter to suppress high-frequency noise from motor drive and ignition systems Voltage stabilization for car infotainment, instrument panel and camera power circuits Power conversion for new energy vehicle on-board charger (OBC) and low-voltage auxiliary power modules 5.Application Fields Automotive ECU control units, BMS battery management systems, ADAS millimeter radar & camera power boards, vehicle T-box telematics modules, car infotainment & instrument clusters, new energy vehicle OBC and low-voltage DC-DC systems, body control modules (BCM), automotive lighting LED drive power supplies, electric water pump/fan motor drive circuits, intelligent driving domain controller power modules.
