Automotive Molded Power Inductors | AS3A322520
Product Introduction
Sunlord AS3A322520 is the thick (2.0mm) version of the AEC-Q200 molded one-piece automotive power inductor family in metric 3225. The taller metal-alloy body pushes saturation current to 19.8A with DCR from 3.2mΩ, for BMS, OBC, high-power DC-DC and ADAS rails up to +150°C.
Core Advantages
- Isat up to 19.8A: the strongest DC-bias performance in the AS3A family.
- Ultra-low DCR from 3.2mΩ: minimal loss in high-current automotive rails.
- Excellent DC-bias flatness: inductance stays stable under heavy load — ideal for multi-phase DC-DC.
- Molded one-piece: no acoustic noise, high shock resistance, closed magnetic circuit.
- AEC-Q200 qualified: halogen-free, RoHS compliant, -55~+150°C.

Cross Reference & Replacement
Cross-reference alternatives: ROHM (100% footprint-compatible AEC-Q200 molded inductors), Taiyo Yuden (molded one-piece with closed magnetic circuit) and Microgate (short lead-time option). AS3A322520 matches their pads and molded characteristics.
Applications
LED headlight drivers, ambient lighting, DRL
BMS, OBC, DC-DC converters
infotainment, instrument cluster, displays
ADAS modules, sensor supply units
FAQ
Q: What is the saturation current of AS3A322520?
A: 4.3–19.8A depending on inductance value — the highest in the AS3A molded family.
Q: Does inductance drop under load?
A: Minimally — the molded iron-alloy core gives excellent DC-bias flatness, ideal for multi-phase DC-DC.
