Caddock MP925 Series

Caddock MP925 Series

The MP925 Kool-Pak® power film resistors from Caddock are a low cost, heat sink mountable design featuring an exposed ceramic heat dissipating mounting surface. The resistance range is from 5KΩ up to 100KΩ with a power rating of up to 25W at +25°C case temperature derated to zero at +150°C. The MP915 series tolerance options available are ±1.0% (standard), ±5.0% and ±20.0% are also available depending on the resistance values required. The MP925 series Kool-Pak® power film resistors are constructed with Caddock's Micronox® resistance film fired onto a flat ceramic substrate. 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 5KΩ and 100KΩ
  • Non-inductive design
  • TCR of -20 to +80 ppm/°C (from 0.5Ω and above)
  • Tolerance of ±1.0% as standard (±5.0% and ±20.0% are available for most resistance values)
  • Power rating of up to 25W at +25°C case temperature derated to zero at +150°C
  • Maximum voltage 500V
  • Maximum temperature 150°C

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.

The below table gives the specifications available for the complete MP900 resistor series including the MP925:
