MP900 and MP9000 Series Kool-Pak® Power Film Resistors

Product catalog summary
Overview: The document provides technical specifications and guidelines for the MP900 and MP9000 Series Kool-Pak® Power Film Resistors, which are designed for high power applications with non-inductive performance. These resistors are available in TO-126, TO-220, and TO-247 styles, offering different power ratings and resistance ranges.
Specifications:
  • MP915 (TO-126 Style): Up to 30 Watts at +25°C, derated to zero at +150°C. Resistance range: 0.010 ohm to 100 K.
  • MP916, MP925, MP930 (TO-220 Style): 100 Watts at +25°C, derated to zero at +175°C. Resistance range: 0.050 ohm to 100 ohm.
  • MP9100 (TO-247 Style): Low-cost, heat sink mountable design with 100 Watts at +25°C, derated to zero at +175°C. Resistance range: 0.050 ohm to 100 ohm.
Construction: The resistors are constructed with Caddock's Micronox® resistance film on a ceramic substrate, providing non-inductive performance. The ceramic substrate is exposed for heat dissipation.
Thermal Design: The power handling capability is based on case temperature. Proper mounting and thermal interface materials are crucial for optimal performance. The document provides detailed mounting instructions, including recommended mounting force and torque specifications.
Derating and Temperature Coefficients: The resistors' power ratings are derated based on case temperature. Temperature coefficients vary by resistance value, with specific ppm/°C values provided for different resistance ranges.
Performance and Reliability: The resistors are tested for load stability, momentary overload, moisture resistance, thermal shock, shock, vibration, and terminal strength, adhering to various Mil-Std-202 methods.
Ordering Information: Resistors are available in specific resistance values and tolerances, with packaging details provided for different models.
Figures and Graphs: The document includes figures illustrating the dimensions of different resistor styles and a derating curve showing power rating versus case temperature.
