Description

The MP850 Kool-Pak® power film resistors from Caddock include an integral metal mounting surface for highly efficient thermal transfer. The resistance range is from 0.2Ω up to 10KΩ with a power rating of up to 50W at +25°C case temperature derated to zero at +150°C. The MP850 series tolerance is ±1.0% as standard (±0.5%, ±2.0%, ±5.0%, ±10.0% and ±20.0% are available for most resistance values). Caddock MP850 Kool-Pak® power film resistors are constructed with Caddock’s Micronox® resistance film fired onto a flat ceramic substrate. The ceramic substrate is bonded to a copper heat sink which becomes the metal mounting surface. This assembly is moulded with the copper heat sink flush with the back surface of the part. The terminal attachment and resistance element geometry are configured to provide outstanding non-inductive performance.

  • Kool-Pak® power film through-hole resistor
  • Resistance values available between 0.2Ω and 10KΩ
  • Copper heat sink integral in the moulded package

  • TCR of 0 to +200 ppm/°C (between 0.05Ω and 0.49Ω), -20 to +80 ppm/°C (from 0.5Ω up to 4.99Ω) and -20 to +50 ppm/°C (from 5Ω and above)
  • 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 50W at +25°C case temperature derated to zero at +150°C
  • Resistor element is electrically isolated from the mounting surface

 

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.
