PWR163 Series Power Resistor
General Information
The PWR163 Series is a DPAK style surface mount power resistor. It has a very low inductance making it ideal for high frequency
applications such as ampli?ers for audio or wireless base stations. It has excellent pulse characteristics as well, allowing it to be used
in current limiting or capacitor discharge circuits.
