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.

MP825 and MP850 Power Film Resistors

Include an Integral Metal Mounting Surface

for Highly Efficient Thermal Transfer

Certain products shown in this catalog are covered by one or more patents, there are also patents pending.

TO-220 Style and TO-126 Style - Non-Inductive Designs

• Copper Heat Sink Integral in the Molded Package.

• Resistance Range of 0.20 ohm to 10.0 K.

• Resistor element is electrically isolated from the mounting surface.

MP820 and MP821 TO-220 Style Power Package

with Metal Mounting Tab

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 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.
