Caddock's Micronox® resistance films are the source of the Type MG Precision High Voltage Resistors' outstanding combination of performance features: • Single-resistor values as high as 10,000 Megohms. • Maximum continuous operating voltages as high as 48,000 volts ("-15" ratings). • Overvoltage capabilities of 150% of standard working voltages for all models and values, (except "-15" ratings). • Resistance Tolerances from ±1.0% to ±0.1%. • Temperature Coefficient, for standard resistance range, of 80 ppm/°C in combination with resistance tolerances as tight as ±0.1%. • Type MG resistors have demonstrated stability of 0.01% per 1,000 hours in extended load life testing of standard resistance range values. This exceptional performance 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 electronics. Preconditioning for Power and Voltage Ratings All power ratings and maximum operating voltage ratings are for continuous duty. These ratings are based on pre- stress voltage levels applied during the manufacturing process to provide for stable resistor performance even under momentary overload conditions. Maximum operating voltages 60% higher than the values listed in the table may be specified by adding "-15" to the model number (Example: MG750-15). Note that overload and overvoltage ratings do not apply to the "-15" resistors. Resistance ranges for "-15" resistors shown in the table are from "-15 Min." to "Standard Max." Non-Inductive Performance Most models are manufactured with Caddock's Non-Inductive Design which uses a 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. Insulation Resistance: 10,000 Megohms, min. Overload/Overvoltage: 5 times rated power with applied voltage not to exceed 1.5 times max- imum continuous operating voltage for 5 seconds .

Caddock's Micronox® resistance films are the source of the Type MG Precision High Voltage Resistors' outstanding combination of performance features: • Single-resistor values as high as 10,000 Megohms. • Maximum continuous operating voltages as high as 48,000 volts ("-15" ratings). • Overvoltage capabilities of 150% of standard working voltages for all models and values, (except "-15" ratings). • Resistance Tolerances from ±1.0% to ±0.1%. • Temperature Coefficient, for standard resistance range, of 80 ppm/°C in combination with resistance tolerances as tight as ±0.1%. • Type MG resistors have demonstrated stability of 0.01% per 1,000 hours in extended load life testing of standard resistance range values. This exceptional performance 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 electronics. Preconditioning for Power and Voltage Ratings All power ratings and maximum operating voltage ratings are for continuous duty. These ratings are based on pre- stress voltage levels applied during the manufacturing process to provide for stable resistor performance even under momentary overload conditions. Maximum operating voltages 60% higher than the values listed in the table may be specified by adding "-15" to the model number (Example: MG750-15). Note that overload and overvoltage ratings do not apply to the "-15" resistors. Resistance ranges for "-15" resistors shown in the table are from "-15 Min." to "Standard Max." Non-Inductive Performance Most models are manufactured with Caddock's Non-Inductive Design which uses a 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. Insulation Resistance: 10,000 Megohms, min. Overload/Overvoltage: 5 times rated power with applied voltage not to exceed 1.5 times max- imum continuous operating voltage for 5 seconds .

Caddock's Micronox® resistance films are the source of the Type MG Precision High Voltage Resistors' outstanding combination of performance features: • Single-resistor values as high as 10,000 Megohms. • Maximum continuous operating voltages as high as 48,000 volts ("-15" ratings). • Overvoltage capabilities of 150% of standard working voltages for all models and values, (except "-15" ratings). • Resistance Tolerances from ±1.0% to ±0.1%. • Temperature Coefficient, for standard resistance range, of 80 ppm/°C in combination with resistance tolerances as tight as ±0.1%. • Type MG resistors have demonstrated stability of 0.01% per 1,000 hours in extended load life testing of standard resistance range values. This exceptional performance 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 electronics. Preconditioning for Power and Voltage Ratings All power ratings and maximum operating voltage ratings are for continuous duty. These ratings are based on pre- stress voltage levels applied during the manufacturing process to provide for stable resistor performance even under momentary overload conditions. Maximum operating voltages 60% higher than the values listed in the table may be specified by adding "-15" to the model number (Example: MG750-15). Note that overload and overvoltage ratings do not apply to the "-15" resistors. Resistance ranges for "-15" resistors shown in the table are from "-15 Min." to "Standard Max." Non-Inductive Performance Most models are manufactured with Caddock's Non-Inductive Design which uses a 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. Insulation Resistance: 10,000 Megohms, min. Overload/Overvoltage: 5 times rated power with applied voltage not to exceed 1.5 times max- imum continuous operating voltage for 5 seconds .
