Power Film Resistors Take On 20 W at 25°C

Nov. 29, 2006
The TR Series from Stackpole Electronics features tolerances to 1% and TCRs as low as 50 ppm.

The TR Series TO-220-style power film resistors can handle up to 20 W at case temperatures up to 25°C. They are available in values from 0.05 Ω to 10 kΩ in tolerances down to 1% and with temperature coefficients of resistance (TCR) as low as 50 ppm. The molded case is isolated from the resistor itself, which allows for easy mounting to a heat sink. The TR 25 and TR 30 versions have screw holes for simple and reliable mounting to a heat sink. The TR 20, with a lower power rating, does not require a heat sink. The resistors are non-inductive, with excellent electrical and environmental stability.

The TR Series is well suited for high-speed switching power supplies, voltage regulation, load resistors in pulse generators, snubber circuits, power amplifiers, UPS systems, and frequency balancing and conversion. They are also useful for many types of power supplies and industrial-grade controls.

AVAILABILITY
The TR Series resistors are available with delivery times of six to eight weeks.PRICING
Prices range from $0.75 to $1.50, depending on quantity and tolerance.FOR MORE INFORMATION
