RIVERSIDE, Calif., April 20, 2010 — Bourns, Inc., a leading manufacturer and supplier of electronic components, today introduced two new power inductors that feature advanced flat wire technology for lower DC resistance and higher current ratings in an ultra small package. Bourns’ innovative power inductor design utilizes a flat wire within a molded magnetically shielded housing that enables lower DC resistance and slightly higher current ratings compared to traditionally used round wire. Designated Bourns® Models SRP4020 and SRP7030F, the new inductors are ideally suited for use in DC/DC converters for mobile electronic devices and computers, as well as data storage and voltage regulator modules. Other applications that can benefit from Bourns’ advanced power inductor design include servers, portable gaming devices, navigation systems, automotive electronics, medical equipment and more.

Bourns® Model SRP4020 features a very compact footprint of 4.8 x 4 mm in 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. Bourns® Model SRP7030F also offers a compact footprint of 7.6 x 6.5 mm in a 3.2 mm height. The inductance range is 0.1 – 10 µH, with a heat rating current up to 32 A and a saturation current up to 60 A.

“Flat wire technology offers a new breakthrough design with lower DC resistance and a compact size, which is very attractive for design engineers of mobile devices or other applications where prolonged battery life is essential,” said Guido Zehnder, product line manager for Bourns’ power inductor products. “We believe the trend for lower DC resistance and smaller sizes in power inductors will continue as applications, and especially mobile devices, will increasingly require more compact, low-power components.”

Pricing and Availability
Bourns® Models SRP4020 and SRP7030F are available now. For complete specifications and additional product information, go to Bourns’ site at As a pricing reference, the new power inductors are priced at $0.68 each per 1,000 pieces.
