Automotive Power Inductors | AS1A4010
Product Introduction
Sunlord AS1A4010 is the ultra-slim 4010 member of the 2025 AS1A automotive power inductor family. With a 1.0mm profile, magnetic shielding and AEC-Q200 qualification it powers LED ambient lighting, cockpit rails and ADAS modules from -55°C to +150°C.
Core Advantages
- Ultra-slim 1.0mm profile: 4.0×4.0mm footprint with minimal height for flat automotive modules.
- 1–22μH coverage: standard filter values for lighting and display rails.
- Heat-resistant +150°C: 2025 AS1A platform for high-temperature zones.
- Magnetic shielding: closed magnetic circuit reduces noise coupling.
- AEC-Q200 qualified: halogen-free, RoHS compliant.
