High-current power inductors

21 July 2010 Passive Components

Bourns has introduced two new power inductors that feature advanced flat wire technology for lower DC resistance and higher current ratings.

The innovative power inductor design utilises a flat wire within a moulded, magnetically shielded housing. The new models SRP4020 and SRP7030F are suited for use in DC/DC converters for mobile electronic devices and computers, as well as data storage and voltage regulator modules.

The SRP4020 features a compact footprint of 4,8 x 4 mm and 2 mm height. The device has an inductance range of 0,22–2,2 μH, with a heat rating current up to 10 A and a saturation current up to 15 A. The SRP7030F also offers a compact footprint of 7,6 x 6,5 mm in a 3,2 mm height. Its inductance range is 0,1–10 μH, with a heat rating current up to 32 A and a saturation current up to 60 A.
