MRC Applications:
The MRC1/2 will dissipate 1/2 watt at 70°C on a 1206 footprint. The MRC is recommended for applications where
board real estate is a major concern. Due to high power density and superior surge handling capability, it is also
recommended as a direct replacement on existing board designs where standard 1206 resistors are marginal or failing.
