D-Pak Style Surface Mount Power Package including Metal Tab - 0.020 ohm to 1.00 Kohm
Use your thermal design experience with power semiconductors in
D-Pak style power packages. This experience will help you get the most out
of this unique family of surface mount 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.

Curve. The case temperature measurement is made on the
metal mounting tab against the molded body.
Derate
resistance of the mounting surface, and the temperature
limitations of the adjacent materials (such as glass epoxy).
Derating ( thermal resistance ) is 0.200 W/°C ( 5.0°C/W ).
0 Power dissipation is 2.5 watts, at an ambient temperature of
25°C, when mounted on a double sided copper board (2 ounce,
G-10 or FR-4) 1 inch x 1 inch x .063 inch (thick).
Custom resistance values can be
manufactured for high quantity

MP725 Surface Mount Power Film Resistors introduce our proven
Micronox ? resistance ?lm system in the widely accepted D-Pak style surface
mount power package. The non-inductive design makes this resistor ideal in
high frequency communications, power switching circuits, and snubbers.
The special performance features of our patented MP725 Surface Mount
Power Film Resistors include:
? D-Pak style power package for surface mount applications.
? Metal tab assists in post surface mount soldering inspection.
? Resistance values to 0.020 ohm for current sense applications.
? Non-Inductive Design.
? Up to 25 Watt power rating at +25°C case temperature.
? Resistor element is electrically isolated from the metal heat sink tab.
