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.

Temperature Coefficient:
Referenced to 25°C,
Designed for heat sink
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.

Ohmite’s new TCH35 TO220
package resistor provides 35W
of steady state power when
properly used in today’s well
defined heat sink applications.
These very low induction
resistors are built under proprie-
tary processes that deliver 75%
more power handling capabil-
ity than other TO220 package
resistors of similar size.
Standard lead forms are
provided for manual or auto-
matic insertion.
A single screw mounting tab
connects to the heat sink and
should be accompanied by the
use of a thermal compound.
The TCH35 Series offers a low
thermal resistance to the heat
sink of <4.28°C/W.
