Automotive Power Inductors | AS1A2012
Product Introduction
Sunlord AS1A2012 is the most compact member of the 2025-launched AS1A automotive power inductor family — heat-resistant, low-loss and AEC-Q200 qualified. The 2012 magnetic-shielded wire-wound structure suits LED ambient lighting, cockpit rails and T-BOX/V2X modules from -55°C to +150°C.
Core Advantages
- Ultra-compact 2012 package: 2.0×1.2×1.0mm saves board space in dense automotive modules.
- Heat-resistant to +150°C: the 2025 AS1A platform is built for high-temperature automotive environments.
- Low loss at light load: 73–310mΩ DCR and 1.2–2.4A Isat match low-power rails like ambient lighting and T-BOX.
- Magnetic shielding: closed magnetic circuit keeps noise away from adjacent RF and V2X circuits.
- AEC-Q200 qualified: halogen-free, RoHS compliant for global automotive programs.
