10Ω : 100 50 Ω : 500 First two digits significant, last digit: number of trailing zeros Mounting Guidelines Introduction The power resistor has extremely low thermal resistances in each axis for maximum conducted, radiated and convection heat dissipation. Using the JEDEC standard JD-51 as a guideline, coupled with your thermal design experience in power semiconductors, you can maximise the potential of this unique SOIC style power resistor. 5W PCB Example A small 40mm x 40mm, 5W, 4-layer test board configuration is illustrated to demonstrate the superior high performance of the SMP power resistor using minimum real estate. 10W PCB Example Mounting details available on request.
