Automotive Power Inductors | AS1A5020
Product Introduction
Sunlord AS1A5020 is the 5020 member of the 2025 AS1A automotive power inductor platform. Closed magnetic circuit, magnetic shielding and AEC-Q200 qualification deliver 0.47–47μH with Isat up to 9A for LED headlights, BMS, OBC, DC-DC and ADAS rails up to +150°C.
Core Advantages
- Isat up to 9A: strong current capability for mid/high-power automotive stages.
- Low DCR from 12mΩ: high efficiency in heavy-load rails.
- 0.47–47μH coverage: wide filter range in one footprint.
- Heat-resistant +150°C: 2025 AS1A platform for high-temperature environments.
- AEC-Q200 qualified: magnetic shielding, halogen-free, RoHS compliant.
