Product Overview
The Bourns CRM Series are high-power thick film chip resistors designed for current sensing and limiting applications. Featuring robust thick film technology, these RoHS-compliant resistors offer power ratings of 0.25W, 0.5W, or 1W at 70 C, with low resistance values available. They are ideal for use in power supplies, stepper motor drives, and as snubber resistors for flyback power supplies.
