Type MS Power Film Resistors Page 1 of 2 Power Film Resistor Family with Wide Resistance Range and +275°C Maximum Temperature With power ratings to 22 Watts and voltage ratings as high as 6,000 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 resistor: • Full power and voltage ratings, without derating: - for non-inductive performance. resistance value up to 10 times. www.DataSheet4U.com - for high resistance values that extend the critical • Higher voltage ratings without the limitations of minimum • Excellent long-term stability. wire size and spacing. Tests demonstrate typical stability of 0.05% per 1,000 hours over extended life. Micronox® Resistance Films Type MS performance begins with Caddock's Micronox® resistance films. Produced exclusively by Caddock Electronics, these proven complex oxide films have been used reliably for over 30 years in Caddock's precision power resistor products. Micronox ® resistance films are fired directly onto a ceramic core at temperatures above 1400°F (760°C). 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. N Caddock's Non-Inductive Design The Serpentine Pattern used in this patented product contain features which enhance high stability in High-Power Resistor applications. Most models are manufactured with Caddock's 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. Carefully Controlled Manufacturing and Test Procedures Assure Compliance with Strict Quality Control Requirements. Manufacturing Control Type MS Resistors are produced under intensive manufacturing controls with processes which include power conditioning, overvoltage conditioning, and maximum temperature conditioning. 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, Micronox® resistance film, and silicone insulating coating. 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. Certain products shown in this catalog are covered by one or more patents, there are also patents pending. Applications Engineering 17271 North Umpqua Hwy.
