Caddock MP821 Series

Caddock MP821 Series
The MP821 Kool-Pak® power film resistors from Caddock offers a resistance range from 0.02Ω up to 9.99Ω and a power rating of up to 20W at +25°C case temperature derated to zero at +175°C. The MP821 series tolerance ±1.0% as standard (±0.5%, ±2.0%, ±5.0%, ±10.0% and ±20.0% are available for most resistance values). The MP821 Kool-Tab® power film resistors are constructed with Caddock's Micronox® resistance film fired onto a flat ceramic substrate which is thermally bonded to the copper heat sink tab. The resistor body is then moulded 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.

  • Tolerance of ±1.0% as standard (±0.5%, ±2.0%, ±5.0%, ±10.0% and ±20.0% are available for most resistance values)
  • Power rating of up to 20W at +25°C case temperature derated to zero at +175°C
  • Resistor element is electrically isolated from the mounting surface

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.
