Automotive Molded Power Inductors | AS3A252012
Product Introduction
Sunlord AS3A252012 is a metal-alloy molded one-piece automotive power inductor (metric 2520) qualified to AEC-Q200. Iron-alloy powder compression forms a closed magnetic circuit with minimal leakage flux, delivering Isat up to 12.8A across -55°C to +150°C.
Core Advantages
- Molded one-piece structure: iron-alloy compression eliminates air gaps — no acoustic noise, high shock resistance.
- Isat up to 12.8A: ultra-strong DC-bias performance in the 2520 class.
- Ultra-low DCR from 4mΩ: minimal conduction loss for high-efficiency DC-DC.
- Closed magnetic circuit: low leakage flux protects adjacent T-BOX and V2X circuitry.
- AEC-Q200 qualified: halogen-free, RoHS compliant, -55~+150°C range.

Cross Reference & Replacement
Cross-reference alternatives: TDK (AEC-Q200 molded one-piece, same footprint), Murata (metal-alloy power inductors with stable supply) and Microgate (short lead-time alternative). AS3A252012 matches their pads and molded-structure 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 is a molded one-piece inductor?
A: Metal-alloy powder is compressed into a single body around the coil — closed magnetic circuit, no glue joints, no acoustic noise and excellent shock resistance.
Q: Does AS3A252012 whine under load?
A: No — the one-piece molded structure eliminates the air gap that causes audible coil noise.
