NEW CLIP MOUNTING METHOD DESIGNED FOR OHMITE’S TK/TN RESISTORS IS THERMALLY SUPERIOR

A simple clip mount developed for Ohmite’s recently launched TK/TN series avoids past problems. Simple to install, the clips add little to the cost of the design, yet prevent the danger of too much torque creating damaging thermal overload. If the resistor is attached to the heatsink too tightly it may suffer diminished contact with the heatsink leading to poor thermal conductivity, whereas the new clip ensures full contact no matter how tightly the resistor is fitted.

In addition to this preferred mounting method, the TN version of the product offers the customer thin film construction in a power package for the first time. Thin film construction has many benefits over thick film, and it is preferred in applications where low noise is required. This is often seen in high frequency applications where any stray inductance or capacitance can cause problems in circuit performance.
