Ordering Information: Model Number: MP915 - 50.0 - 1% Resistor Value: Tolerance Packaging: MP915, MP916, MP925, and MP930 resistors are packaged in plastic shipping tubes, 50 pieces per tube. These resistors are available in a 50 piece minimum quantity and in full tube quantity increments (i.e. 50, 100, 150, etc.). The MP9100 resistors are packaged in plastic shipping tubes, 25 pieces per tube. Construction of MP900 and MP9000 Series: The MP900 and MP9000 Series Kool-Pak (R) Power Film Resistors are constructed with Caddock's Micronox(R) 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. Recommended limitation of use: Caddock does not recommend the MP900 and MP9000 Series Resistors for use in military or space applications. These products are recommended by Caddock for use only in commercial/industrial applications. Caddock has qualified these devices, for their intended use, to perform according to catalog specifications. Caddock does not maintain a military and/or space level reliability program for these devices. Caddock does not provide support for use of these devices in military and space applications. These products have matte tin plated leads (with 100% tin plating), there is no other lead finish offered for the MP900 and MP9000 Series Resistors. Any use of this product in a military program, against this recommended limitation of use, will be completely supported by the customer program design activity and component engineering activity based on their complete evaluation and testing, there will be no support provided by Caddock for this use. Space equipment programs (both the engineering phase and the flight phase) must only use selected Caddock products that have been purchased in accordance with NASA GSFC specifications.

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.
