Automotive Molded Power Inductors | AS3A322512
Product Introduction
Sunlord AS3A322512 is a metal-alloy molded one-piece automotive power inductor (metric 3225, 1.2mm slim) qualified to AEC-Q200. Iron-alloy compression with closed magnetic circuit delivers low DCR, big saturation current up to 14A and quiet, shock-resistant operation from -55°C to +150°C.
Core Advantages
- Low DCR from 5mΩ: high-efficiency power conversion in the 3225 class.
- Isat up to 14A: strong DC-bias margin for automotive DC-DC stages.
- Molded one-piece: no air gap — no acoustic noise, high shock and vibration resistance.
- 1.2mm slim profile: fits flat automotive modules and T-BOX designs.
- AEC-Q200 qualified: halogen-free, RoHS compliant.

Cross Reference & Replacement
Cross-reference alternatives: Cyntec (global molded-inductor benchmark, same pads), Vishay (AEC-Q200 power inductors with global coverage) and Microgate (short lead-time option). AS3A322512 matches their footprints and molded characteristics.
Applications
LED headlight drivers, ambient lighting, DRL
BMS, OBC, DC-DC converters
infotainment, instrument cluster, displays
T-BOX modules, V2X units, gateways
FAQ
Q: What current can AS3A322512 handle?
A: Saturation current 2.9–14A and RMS current up to 11A depending on inductance value.
Q: Is AS3A322512 drop-in for Cyntec molded inductors?
A: Yes — metric 3225 pads, matching DCR/Isat and the same one-piece molded construction with AEC-Q200.
