Calculating Power Resistor Surge Survivability
A power resistor may be used in motor control circuits and is therefore likely to be subject to repeated short term (transient) surge conditions. It is essential to choose the correct thick film power resistor to ensure it will operate, without degradation, over the required lifetime of the system. Many designers underestimate the potential damage to resistors and other components caused by a power surge hence in this article we cover the key issues to consider.
