Surface Mount Terminations

ATR offer a wide selection of SMT chip terminations handling input power
levels up to 250W and covering frequency ranges up to 4 GHz.
the surface mount termination is improved by increasing the solderable
grounding area. This eliminates the need for bolt down heat sinks and
tabs, thereby reducing assembly costs.
