SRP High-Current Shielded Power Inductors


The Bourns® SRP Inductors (most models) are designed with flat wire and magnetic alloy compound.

Inductor winding is completely molded with iron powder compound as magnetic core. Such construction yields SRP uniquely compact, low DC resistance, high current carrying capability and magnetically shielded. Flat wire coil has better current conductivity than conventional round wire for high frequency application. Iron core SRP inductor has high saturation current characteristic than traditional gapped-ferrite core inductor.
