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.
