Bourns SRP4012 Series Power Inductors

Bourns introduces the SRP4012 Series Power Inductors, which offer one of the two smallest footprints and features with the lowest profile component in the SRP High Current Power Inductor product family. Bourns SRP4012 Series Power Inductors offer a 4.7 x 4 mm footprint in a 1.2 mm height with an inductance range of 0.22 - 1.5 μH, a heat rating current up to 9 A, and a saturation current up to 10 A. The flat wire and magnetic alloy compound molded construction offers a compact size, low DC resistance, high current carrying capability and magnetically shielded inductor. Bourns SRP4012 Series Power Inductors are ideal for use in DC/DC converters for mobile electronic devices, computers, data storage and voltage regulator modules. The low profile feature makes them especially attractive for application in ultrathin electric devices.
