It’s an unfortunate fact that a resistor can fail under pulse loads. When pulse power is dissipated to the device’s resistive element, it generates heat and increases the resistor’s temperature.

Fixed linear resistors are commonly required in a diverse range of applications, from medical and aerospace electronics, to communications and automotive, to lighting and general industrial equipment.

Many electronic circuits are exposed to high pulse loads. In some applications, these occur regularly, such as in pulse-width-modulated (PWM) devices. In others, pulses are incidental, but also ...
