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 amplifiers 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.

Overload Duration in Seconds
The energy absorbed by the resistor expressed in Joules can be calculated by
multiplying the peak power of the pulse in watts times the length of the pulse in
seconds.
The energy should not exceed the limits shown in the graph. The overload voltage
should not exceed 1.5 times the maximum operating voltage.
Specifications are subject to change without notice.
Customers should verify actual device performance in their specific applications.
