The TAH20 is a completely

encapsulated thick film resistor

in the TO220 package outline.

Rated for 20 watts @ 25°C

case temperature, these resis-

tors are electrically isolated,

and molded in a high tempera-

ture case.

mounting, the symmetrical

package is ready for use with

snap-on style heat sinks (we

recommend use of thermal

grease). The TAH20 Series is

very low induction, and avail-

able in a wide range of resis-

tance values in standard 5%

tolerance. 1% tolerance avail-

able by special order.
