MP925 Power Film Resistors

The MG Precision High Voltage Resistors has been proven through many years of use in equipment that demands the highest reliability and stability, including TWT amplifiers, X-Ray systems, geophysical instruments and medical electronic. Most models are manufactured with Caddock's non-inductive design. KEY FEATURES Single-resistor values as high as 10 000 Megaohms Maximum continous operating voltages as high as 48 000 Volts Resistance Tolerances from 1% to 0.1% Temperature Coefficient, for standard resistance range, of 80 ppm/°C om combination with resistance tolerances as tight as 0,1%

Twelve standard models in five network arrangements of Caddock's 1787 Current Sense Resistor Networks provide the specific accuracy and resistance values required for a wide range of current measuring instruments and circuits. Type 1787 Current Sense Resistor Networks utilize Caddock's Micronox® resistance films and advanced high thru-put laser manufacturing capabilities to achieve many vital advantages in precision current measurement circuits, including laboratory and bench-type digital instrumentation: The thin-profile single-package configuration replaces as many as four discrete current sense resistors. The monolithic construction and standardized lead spacing simplify installation. Caddock Micronox® resistance films provide exceptional stability for improved long-term measurement accuracy.

0.020 Ω to 10.0 kΩ; ±1%; 20 W; TO-220 Style; Power Film Caddock Electronics’ MP820/MP821 series of power film resistors in a TO-220 style power package feature a metal heat sink mounting tab. Within the MP820/MP821 series, 61 different power film resistors are available with standard resistance values ranging from 0.020 Ω to 10.0 kΩ.   The MP820/MP821 series power film resistors are constructed with Caddock Electronics’ Micronox® resistance film fired onto a flat ceramic substrate which is thermally bonded to the copper heat sink tab. The resistor body is then molded with a high temperature molding compound to finish the metal tab TO-220 package. The lead wire attachment and resistance element geometry are configured to provide outstanding non-inductive performance.   Use your thermal design experience with power semiconductors in TO-220 style power packages to help you get the most out of this unique family of power resistors. The thermal design issues are the same where power handling capability is based on the case temperature which is maintained in your design.  At +25 °C case temperature, the MP820/MP821 series allow up to 20 W, derated to zero at +175 °C. Standard tolerance is ±1%, other tolerances (±0.5%, ±2%, ±5%, ±10% and ±20%) are available for most resistance values on request.  Key Features: TO-220 Style Power Package 20 W at +25 °C Case Temperature, Derated to Zero at +175 °C Metal Heat Sink Mounting Tab Resistor Element Is Electrically Isolated From the Mounting Surface Non-Inductive Design for High-speed Switching, Snubbers and RF Applications Temperature Coefficient Starting at -20 to +50 ppm/°C (5.00 Ω and Above) and up to 0 to +300 ppm/°C (0.049 Ω and Below) Operating Temperature -55 to +175 °C Very Low Inductance: 10 nH typical

The HVD Ultra-Precision Voltage Dividers are monolithic voltage dividers built with ceramic sendwich construction. These voltage dividers have ultra-precision performance in the range of 1500 Volts DC to 5000 Volts DC. These dividers are ideal for high performance voltage divisions applications in medical equipment, laboratory equipment, analytical instruments, etc.

The exceptional performance of this extensive family of 1776 Precision Decade Resistor Voltage Dividers has been achieved through the special combination of advantages provided by Caddock's Tetrinox resistance films. This advanced film resistor technology provides the performance characteristics required by the precision input signal ciruits of both bench-type and laboratory digital instruments. There are now 39 standard models in the expanded family of Type 1776 precision resistor networks that include: 3, 4, and 5 - decade voltage dividers with ratios from 10:1 to 10,000:1. 1,200 volts continuous ratings and overvoltage to 2,000 volts. Many combinations of Ratio and Absolute Tolerance, and Ratio and Absolute Temperature Coefficient.
