Description

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 is ±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 moulding 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.
