Applications
The PPS-1 will dissipate 1 watt at 70°C on a 2010 footprint. The PPS-1 is recommended for applications where
board real estate or component/board TCE mismatch is a major concern. It is also recommended in circuits
where a standard 2010 resistor exhibits marginal or unacceptable performance due to high power density/surge
handling demands.
