Graphite thermal pads for demanding power electronics applications

Ohmite TAP-TP1 Graphite Thermal Pads, available now from Mouser, are thermal interface materials (TIMs) designed for applications necessitating reliable performance, long life, low contact resistance, low maintenance, and high thermal conductivity. The thermal pads assure an exact fit and decrease module-to-module variation during assembly. The compressibility of the material enhances surface contact, reducing thermal impedance. The material compression compensates for flatness variations of up to 125μm. The high in-plane thermal conductivity of this material decreases hot spots.

These thermal pads are designed for long-life applications with extreme heat cycles and are made of flexible graphite that is engineered for demanding power electronics applications.

The does not degrade in performance from initial install and over the life of the application. The assembly-ready foil form factor removes dispensing and cleaning processes. Easy installation removes the requirement for burn-in or re-torque, enabling a single-step install. Minimal outgassing stops fouling of optics in lighting applications.

Typical applications include UPS and inverters; motor drives; base stations/telecommunication; thermo electric devices; power supply modules, rectifiers and chargers; high-performance computers and servers; EV, HEV, and PHEV modules.
