Power Resistor Heatsinks

Riedon™ products by Bourns

This presentation will discuss heatsink considerations for Riedon power resistor products. The concepts and methods used to determine heat sink requirements for Riedon high power resistors will be covered. The methods follow normal practice used to design heat sink systems for power semiconductors, and are directly applicable to power resistors.
