PPS-1 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.
