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.
