TDK-EPC has released the SPM6530-H SMD power inductor series with an extended temperature range. The new parts are now rated for temperatures of up to 125°C and currents up to 28,5 A.
The components are thus suitable for automotive use as choke coils in the DC-DC converters of brake systems, headlights and engine control units (ECU).
Because applications in automotive electronics are exposed to severe environmental conditions, the heat resistance properties of the new series has been greatly improved over those of existing products, which are used as choke coils in notebook PCs and servers. The SPM6530-H inductor can be used over a broad temperature range from -40°C to +125°C. The coil features a solid body made from a high saturation flux density metallic material. The 6,5 mm square coil achieves the same DC superimposition characteristics as a 10 mm square ferrite coil, thus allowing the new inductor to be made smaller and lighter. In addition, its lead-frame design offers enhanced mechanical stability and high dimension accuracy.
