TO-220 Style and TO-126 Style - Non-Inductive Designs
Page 1 of 2
Use your thermal design experience with power semiconductors in TO-220 and
TO-126 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 MP820 and 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 molded with a high temperature
molding 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.

Construction of MP825 and MP850:
The MP825 and MP850 Kool-Pak® Power Film Resistors are constructed with Caddock's
Micronox® resistance film fired onto a flat ceramic substrate. The ceramic substrate is
bonded to a copper heat sink which becomes the metal mounting surface. This
assembly is molded with the copper heat sink flush with the back surface of the part. The
terminal attachment and resistance element geometry are configured to provide
outstanding non-inductive performance.

All power and associated overload ratings are derated
based upon case temperature using the derating curve.
The case temperature is measured at the center of the
metal mounting surface, with the part properly mounted
and under electrical load. Without a heat sink, when in
free air at +25°C, the MP820, MP821, and MP850 are
rated for 2.25 watts, the MP825 is rated for 1.25 watts.

The thermal design should satisfy the following equation:
Inductance: 10nH typical in series when mea-
sured at a point 0.2 inches from the resistor body.
Case Temperature (T ) + [Thermal Resistance (R
) x power applied (Watts)] ≤ TMAX considering the full

c
operating temperature range of the application.
Mounting Note: Mount on a smooth, clean and flat heat sink surface with a thermal interface material, such
as thermal grease. The entire exposed metal backface portion must be in thermal contact with the heat sink.
When screw mounting, use a compression washer which provides a mounting force of 150 to 300 pounds
(665 to 1330 N). This will provide sufficient pressure on the package over time and through large temperature
variations to maintain the maximum power dissipation capability. Mounting torque to avoid package damage
is 8 in-lbs (0.90 N-m). If a spring clip is used, a clip force of 8 to 30 pounds (35 to 130 N) is recommended to
be applied to the center of the package. The clip should be round or smooth in the contact area to avoid
concentrating the load on a small point of the plastic body of the package. Another mounting option is to use
a pressure bar method which can achieve a greater mounting force with a greater contact area.
DWV: The dielectric strength rating of 1500 VrmsAC
is based upon connections made between
terminals shorted and either the metal surface the
part is mounted to or a metal clip in contact with the
top surface of the part.
Insulation Resistance: 10,000 Megohms, min.
The resistor element is electrically isolated from
the mounting surface.
For additional applications information regarding mounting and pulse handling see the Caddock
Applications Notes at caddock.com or contact Applications Engineering.
Load Stability: 2,000 hours at rated power.
