an Exposed Ceramic Heat Dissipating Mounting Surface

The MP900 and MP9000 Series Kool-Pak® Power

Film Resistors are constructed with Caddock's

Micronox® resistance lm red onto a at ceramic

substrate. The terminal attachment and resistance

element geometry are configured to provide

outstanding non-inductive performance. The

ceramic substrate is positioned in the molded

package such that the resistor element and terminal

attachment areas on the substrate are

encapsulated in the molded body with the other side

of the ceramic being exposed ush with the back

mounting surface of the device. This construction is

covered by one or more issued patents, also

patents pending.

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

ceramic mounting surface, with the part properly

mounted and under electrical load. Without a heat sink,

when in free air at +25°C, the MP915 is rated for 1.25

watts, the MP916, MP925, MP930 are rated for 2.25

watts, and the MP9100 is rated for 3.5 watts.

The thermal design should satisfy the following equation:

Case Temperature (Tc) + [Thermal Resistance (RθJC) x power applied (Watts)] ≤ TMAX considering the full

operating temperature range of the application.

Mounting Note: Mount on a smooth, clean, and at heat sink surface with a thermal interface material, such

as thermal grease. The entire exposed ceramic 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 sufcient pressure on the package over time and through large temperature varia-

tions 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 concen-

trating 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.

For additional applications information regarding mounting and pulse handling see the Caddock

Applications Notes at caddock.com or contact Applications Engineering.
