SRN Series Semi-Shielded Power Inductors

SRN Series Semi-Shielded Power Inductors

Bourns introduces eight new semi-shielded power inductor series - models SRN2010, SRN2012, SRN2510, SRN2512, SRN4012, SRN4026, SRN5040 and SRN6028, designed using semi-magnetic shielding technology. Instead of the conventional ferrite shield, the magnetic shield of the SRN series utilizes an epoxy-ferrite powder mixture resin. This compound is applied to the perimeter of the inductor which envelops the winding. As a result, the SRN model series inductors provide an effective magnetic shielding while emitting lower radiation compared to non-shielded inductors. In addition, the models offer a reduced footprint and cost savings to comparably-sized conventional ferrite shield inductors.

The semi-shielded SRN model series combines the features of non-shielded and shielded inductors, making them ideal for use in DC/DC converters which provide power management to mobile electronic devices, computers, data storage devices and consumer electronics. The SRN series is also well-suited for industrial applications such as LED lighting, control circuits and GPS.
