Product information "MP820/MP821 Power Film Resistors"

0.020 Ω to 10.0 kΩ; ±1%; 20 W; TO-220 Style; Power Film

Caddock Electronics’ MP820/MP821 series of power film resistors in a TO-220 style power package feature a metal heat sink mounting tab. Within the MP820/MP821 series, 61 different power film resistors are available with standard resistance values ranging from 0.020 Ω to 10.0 kΩ.  
The MP820/MP821 series power film resistors are constructed with Caddock Electronics’ Micronox® resistance film fired onto a flat ceramic substrate which is thermally bonded to the copper heat sink tab. The resistor body is then molded with a high temperature molding compound to finish the metal tab TO-220 package. The lead wire attachment and resistance element geometry are configured to provide outstanding non-inductive performance.  
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 MP820/MP821 series allow up to 20 W, derated to zero at +175 °C. Standard tolerance is ±1%, other tolerances (±0.5%, ±2%, ±5%, ±10% and ±20%) are available for most resistance values on request.
Key Features:

  • TO-220 Style Power Package
  • 20 W at +25 °C Case Temperature, Derated to Zero at +175 °C
  • Metal Heat Sink Mounting Tab
  • Resistor Element Is Electrically Isolated From the Mounting Surface
