Vishay Intertechnology Inc. has introduced the ThermaWick THJP series surface-mount thermal jumper 
Source: Vishay Intertechnology Inc.chip. The Vishay Dale Thin Film device allows designers to transfer heat from electrically isolated components by providing a thermal conductive pathway to a ground plane or common heatsink.
Featuring an aluminum nitride substrate with high 170 W/m° K thermal conductivity, the chip is capable of reducing the temperature of connected components by over 25%. This reduction allows designers to increase the power handling capability of these devices or extend their useful life at existing operating conditions, while maintaining the electrical isolation of each component. By protecting adjacent devices from thermal loads, overall circuit reliability is improved.
The THJP’s low capacitance down to 0.07 picofarad makes it an excellent choice for high frequency and thermal ladder applications. The thermal conductor will be used in power supplies and converters, radio frequency amplifiers, synthesizers, pin and laser diodes, and filters for AMS, industrial and telecommunications applications.
The device is available in six case sizes from 0603 to 2512, with custom sizes available. The 0612 and 1225 cases feature long side terminations for additional heat transferring capability. The thermal jumper is available with lead (Pb)-bearing and Pb-free wraparound terminations.
Samples and production quantities of the ThermaWick THJP series thermal jumper are now available.
