The MP821 Kool-Pakยฎ power film resistors from Caddock offers a resistance range from 0.02ฮฉ up to 9.99ฮฉ and a power rating of up to 20W at +25ยฐC case temperature derated to zero at +175ยฐC. The MP821 series tolerance is ยฑ1.0% as standard (ยฑ0.5%, ยฑ2.0%, ยฑ5.0%, ยฑ10.0% and ยฑ20.0% are available for most resistance values). The MP821 Kool-Tabยฎ power film resistors are constructed with Caddockโs Micronoxยฎ 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.
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.
