The MP900 and MP9000 Series Kool-Pak®
 Power 
Film Resistors are constructed with Caddock's 
Micronox®
 resistance film fired onto a flat 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 flush with the back 
mounting surface of the device.  This construction is 
covered by one or more issued patents, also 
patents pending.
For custom resistance values and tolerances contact 
applications engineering.

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 (T
c
) + [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 flat 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 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.
For additional applications information regarding mounting and pulse handling see the Caddock 
Applications Notes at caddock.com or contact Applications Engineering.
