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. - for high resistance values that extend the critical resistance value up to 10 times.
• Higher voltage ratings without the limitations of minimum wire size and spacing.
• Excellent long-term stability. 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 ® complex metal oxide resistance fi lms. Produced exclusively by Caddock Electronics, these proven complex oxide fi lms 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. 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 fl ux fi elds over the entire length of the resistor. This effi cient 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 effi cient 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 certifi cation and testing of all materials, to the su per vi sion of manufacturing processes, all Caddock Type MS Power Film Resistors are produced under pro ce dures that have been approved for conformance to the requirements of Mil-I-45208 in many recent surveys as described on page 8. Reliability Verifi cation Type MS resistors are included in the Caddock Reliability Testing Program. Conformance to specifi cation parameters including Extended Life, Shock, Vibration, and Humidity are verifi ed 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 fi lm, and silicone insulating coating. Carefully Controlled Manufacturing and Test Procedures Assure Compliance with Strict Quality Control Requirements.
