Product information "MP915 Power Film Resistors"

0.020 Ω to 1.00 kΩ; ±1%, ±5%; 15 W; TO-126 Style; Power Film

Caddock Electronics’ MP915 series of power film resistors in a TO-126 style power package feature a heat sink mountable design with an exposed ceramic heat dissipating mounting surface. Within the MP915 series, 52 different power film resistors are available with standard resistance values ranging from 0.020 Ω to 1.00 kΩ.

The MP915 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-126 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 MP915 series allow up to 15 W, derated to zero at +150 °C. Standard tolerance is ±1% for all resistance values 0.050 Ω and above. Below 0.050 Ω the tolerance is ±5%. Lower tolerances (5% and 20%) are available for most resistance values on request.
