Automotive Power Inductors | AS1A4030
Product Introduction
Sunlord AS1A4030 is the high-Isat 4030 member of the 2025 AS1A automotive power inductor platform. With DCR from 14mΩ and saturation current up to 7.9A, it feeds LED headlights, BMS, OBC, high-power DC-DC and ADAS rails from -55°C to +150°C.
Core Advantages
- High Isat up to 7.9A: strong DC-bias margin for high-power automotive stages.
- Ultra-low DCR from 14mΩ: minimal conduction loss in heavy-load rails.
- 1–68μH coverage: power-stage and filter values in one footprint.
- Heat-resistant +150°C: 2025 AS1A platform for high-temperature zones.
- AEC-Q200 qualified: magnetic shielding, halogen-free, RoHS compliant.

BMS, OBC, high-power DC-DC
infotainment, instrument cluster, displays
ADAS modules, sensor supply units
FAQ
Q: What is the saturation current of AS1A4030?
A: 0.9–7.9A depending on inductance value — with DCR from 14mΩ for heavy-load rails.
Q: Does AS1A4030 work in ADAS modules?
A: Yes — magnetic shielding keeps EMI low around sensors, and the -55~+150°C range covers ADAS environments.
