Product information "MP925 Power Film Resistors"

5.00 to 100 kΩ; ±1%; 25 W; TO-220 Style; Power Film

Caddock Electronics’ MP925 series of power film resistors in a TO-220 style power package feature a heat sink mountable design with an exposed ceramic heat dissipating mounting surface. Within the MP925 series, 16 different power film resistors are available with standard resistance values ranging from 5.00 kΩ to 100 kΩ.

The MP925 series power film resistors are constructed with Caddock Electronics’ Micronox® resistance film fired onto a flat ceramic substrate. The terminal attachment and resistance element geometry are configured to provide outstanding non-inductive performance.

The ceramic substrate is positioned in the molded package such that the resistor element and terminal attachment areas on the substrate are encapsulated in the molded body with the other side of the ceramic being exposed flush with the back mounting surface of the device.

Use your thermal design experience with power semiconductors in TO-220 style power packages to help you get the most out of this unique family of power resistors. The thermal design issues are the same where power handling capability is based on the case temperature which is maintained in your design.

At +25 °C case temperature, the MP925 series allow up to 25 W, derated to zero at +150 °C. Standard tolerance is ±1%, lower tolerances (5% and 20%) are available for most resistance values on request.
