Increased temperature characteristics (+125 ° C), use from PC and server to car

TDK Corp. subsidiary -EPC TDK Corporation (President: Jianhong the vessel, hereinafter referred to as TDK -EPC) developed for the automotive brake systems and car headlights, electronic engine control unit (ECU) power supply circuit of DC-DC converter The choke coil of the SMD type power inductor SPM6530-H has been put into mass production since April 2011.

This product takes into account the harsh environment of the vehicle. For the choke coil products originally used in notebook computers and servers, the temperature range is extended to -40 ° C to + 125 ° C to improve the heat resistance. Further, the coil portion is integrally molded using a metal magnetic material having a high saturation magnetic flux density, and the DC superposition characteristic corresponding to a 10 mm square ferrite coil is obtained in a size of 6.5 mm square, thereby achieving a small size and a thinner shape. At the same time, the terminal adopts an external structure and improves the dimensional accuracy and terminal plating level.
