Improving heat dissipation with CoolMag™

Premo has achieved new advancements with CoolMag™ regarding heat dissipation techniques in combination with new techniques to produce iron powder magnetic core (FeSi6) to increase the impedance versus frequency and at the same time extend the saturation level of the core.
Designed for OBC and/or DCDC converters where filtering at the output is mandatory and the increasing of power delivered cause heating in the power inductive components and other critical failures such as magnetic core saturation.

Premo - CoolMag

CoolMag™ is a thermally conductive compound able to fill any space between winding and core (and between core and heat-sink in case of use aluminum or magnesium dissipation). The thermal conductivity of CoolMag™ can be between 1.5 and 1.8 W/mK, which is enough to reduce the temperature gradient in more than 40ºC. CoolMag™ makes extending the operation temperature range possible, increasing the reliability of power inductive components as well as of OBC and/or DCDC converters.
