Bourns CRM Series Thick Film Chip Resistor, 100R ±5% 2W 2512

The Bourns CRM Series SMD chip resistor is a high-power, thick film component engineered for demanding current sensing applications. It features a robust construction with a thick film resistive layer, composed of a metal oxide mixture, printed onto a high-stability ceramic substrate. This design ensures reliable performance and consistent resistance values under load.

The resistive element is protected by a durable epoxy overcoat, enhancing its mechanical strength and environmental resistance. For easy and reliable PCB assembly, the component features electroplated tin (Sn) outer terminations, optimised for standard soldering processes. It operates effectively across a wide temperature range from -55°C to +155°C, making it suitable for a variety of industrial and commercial electronics.

Primary Applications

This high-power resistor is ideally suited for circuits where accurate current measurement and power dissipation are critical. Its typical uses include current sensing modules in power supplies, snubber circuits in flyback power supplies, and driver stages for stepper motors. It provides a reliable and precise resistive solution for managing power and protecting sensitive components.
