AS1A8040 | Automotive Magnetically Shielded Wire-Wound Power Inductors (AS1A)
Product Introduction
Sunlord AS1A8040 is an automotive magnetically shielded wire-wound power inductor in metric 8040 (8.0×8.0×4.0mm), released in the 2025 AS1A series. A high-performance ferrite core with winding and a shielded closed magnetic path delivers low loss and high reliability; halogen-free, RoHS compliant, AEC-Q200-G0 qualified, 1μH~68μH from -55°C~+150°C for ADAS, infotainment, LED lighting and airbag power.
Core Advantages
- Automotive Magnetically Shielded Wire-Wound Power Inductors (AS1A): metric 8040 (8.0×8.0×4.0 mm), 1.0–68 μH — high-performance ferrite core with winding in a magnetically shielded closed path, AEC-Q200-G0.
- Low DCR, high current: DCR 0.008~0.2Ω; saturation current up to 12A — high DC-bias performance in a metric body.
- Compliance: Halogen-free, RoHS compliant.
- Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.
