MRC Applications:
The MRC1/2 will dissipate 1/2 watt at 70°C on a 1206 footprint, while the MRC 1 will dissipate 1 watt at 70°C on a
2010 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 and 2010 resistors are marginal or failing.
