Stackpole's TR series now offers power ratings of 20W to 50W for the TO-220 packages and 100W for the TO-247 package. These non-inductive and RoHS compliant packages are suited for use with power ICs on heat sinks to help maintain the 25 degree C film temperature. The TR is available in tolerances as tight as 0.5% tolerance and TCR as low as 50 ppm. TR series power resistors are available with tolerances from 0.5% to 10%, TC's of 50ppm to 300ppm, and Ohmic values of 0.05 to 1M
In addition, the TR has excellent environmental performance. This makes the TR suited for a wide variety of applications such as radio and satellite communication, automotive and aviation controls, and industrial automation.
Pricing for the TR series ranges from $1.50 each to $5.40 each in full package quantities. Contact Stackpole or one of our franchised distributors for volume pricing. Many popular sizes and resistance values are currently in stock.
