TT Electronics’ TJC series thermal jumper chips enable circuit designers to manage temperature rise in compact power electronic assemblies. The components provide a thermally conductive pathway with electrical isolation for management of PCB hotspot areas. Aluminium nitride, which has nearly five times the thermal conductivity of alumina, is employed in the thermal jumper chip to keep compact electronic assemblies cooler which enhances product reliability.
The TJC series boasts greater thermal conductivity than the equivalent footprint of 70µ copper, and therefore gives better thermal connection than an uninterrupted trace. Available in a case size as small as 0603, the component’s compact mass and design minimizes PCB area and total assembly size and weight. Suitable applications include power supplies, power amplifiers, RF amplifiers, and high-power laser diode applications that may be found in the aerospace, medical, and industrial markets.
