Power Film Resistor Family with Wide Resistance Range and +275degC Maximum Temperature With power ratings to 22 Watts and voltage ratings as high as 6000 volts in an axial-lead resistor with values to 30 Megohms the Type MS Power Film Resistors deliver the performance capabilities that can simplify circuit design and reduce equipment cost and complexity Type MS Power Film Resistors provide all these features in a single resistorbull Full power and voltage ratings without derating

- for non-inductive performance- for high resistance values that extend the critical

resistance value up to 10 timesbull Higher voltage ratings without the limitations of minimum

wire size and spacingbull Excellent long-term stability

Tests demonstrate typical stability of 005 per 1000hours over extended life

Micronoxreg Resistance Films Type MS performance begins with Caddocks Micronoxreg resistance films Produced exclusively by Caddock Electronics these proven complex oxide films have been used reliably for over 30 years in Caddocks precision power resistor products Micronoxreg resistance films are fired directly onto a ceramic core at temperatures above 1400degF (760degC) These resistance films have demonstrated outstanding stability when exposed to a high ambient temperature thermal shock and high power densities This unique approach to precision power resistors opens new design possibilities by providing a wider resistance range precise temperature characteristics and higher temperature and power handling capability

The Serpentine Pattern used in this patented product contain features which enhance high stability in High-Power Resistor applications Most models are manufactured with Caddocks Non-Inductive serpentine resistive pattern that provides for neighboring lines to carry current in opposite directions thereby achieving maximum cancellation of flux fields over the entire length of the resistor This efficient non-inductive construction is accomplished without derating of any performance advantages The result is a truly non-inductive resistor that is about as inductive as a straight piece of wire the length of the resistor body This efficient design means faster settling times and minimum distortion in all types of high frequency circuits

Manufacturing Control Type MS Resistors are produced under intensive manufacturing controls with processes which include power conditioning overvoltage conditioning and maximum temperature conditioning

Quality Control From the certification and testing of all materials to the supervision of manufacturing processes all Caddock Type MS Power Film Resistors are produced under procedures that have been approved for conformance to the requirements of Mil-I-45208 in many recent surveys as described on page 8

Reliability Verification Type MS resistors are included in the Caddock Reliability Testing Program Conformance to specification parameters including Extended Life Shock Vibration and Humidity are verified on a periodic basis Data from Type MS resistors can be compared by similarity to other Caddock resistor types since Type ML MM MS MP MG and MK represent an identical combination of materials - aluminum oxide substrate Micronoxreg resistance film and silicone insulating coating

Carefully Controlled Manufacturing and Test Procedures Assure Compliance with Strict Quality Control Requirements
