ACPR1208S | Shielded SMD Coupled Inductors (ACPR)
Product Introduction
Sunlord ACPR1208S is a shielded automotive coupled inductor in 12.5×12.5×8.5mm. A dual-winding coupled structure delivers high efficiency, high coupling coefficient and low DCR; AEC-Q200 qualified, -50°C~+150°C operation, usable in parallel or series connection for SEPIC / Zeta / Flyback topologies, power coupling or as a common-mode choke in LED-driver and OBC / DC-DC designs.
Core Advantages
- Shielded SMD Coupled Inductors (ACPR): 12.5×12.5×8.5 mm, high efficiency and high coupling — dual-winding coupled structure — high efficiency, high coupling coefficient and low DCR, AEC-Q200.
- Low DCR, high current: DCR 25mΩ~280mΩ (Max); saturation current up to 12.9A — high DC-bias performance in a 12.5×12.5×8.5mm body.
- Compliance: RoHS compliant.
- Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

FAQ
Q: What is a coupled inductor used for?
A: Two coupled windings let one magnetic component serve two phases or act as a transformer — the basis of SEPIC, Zeta and Flyback converters, or as a common-mode choke, injecting and returning energy efficiently.
Q: Can the two windings be connected in series or parallel?
A: Yes — ACPR supports both series (higher inductance / transformer use) and parallel (higher current) connection depending on the topology.
