resistance ?lms 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 coef?cient, 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 speci?ed 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 ?ux ?elds over the entire length of the resistor. this ef?cient 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 . type 1: dc voltage type 2: dc voltage or v rms ac thermal shock: mil-std-202, method 107, cond. c, r 0.25% max. moisture resistance: mil-std-202, method 106, r 0.4% max. load life: 1,000 hours at +125c at rated voltage, not to exceed rated power. solderable leads encapsulation: high temperature silicone conformal. temperature coef?cient: page 1 of 2 28_il110.1004 sales and corporate of?ce 1717 chicago avenue riverside, california 92507-2364 phone: (951) 788-1700 fax: (951) 369-1151 applications engineering 17271 north umpqua hwy. roseburg, oregon 97470-9422 phone: (541) 496-0700 fax: (541) 496-0408 e-mail: caddock@caddock.com ?

resistance ?lms 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 coef?cient, 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 speci?ed 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 ?ux ?elds over the entire length of the resistor. this ef?cient 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 . type 1: dc voltage type 2: dc voltage or v rms ac thermal shock: mil-std-202, method 107, cond. c, r 0.25% max. moisture resistance: mil-std-202, method 106, r 0.4% max. load life: 1,000 hours at +125c at rated voltage, not to exceed rated power. solderable leads encapsulation: high temperature silicone conformal. temperature coef?cient: page 1 of 2 28_il110.1004 rhopoint components ltd. holland road hurst green oxted, surrey, rh8 9ax tel: +44 (0)1883 717988 fax: +44 (0)1883 712938 e-mail: sales@rhopointcomponents.com web: www.rhopointcomponents.com rhopoint components ltd. il-110.019 c b a 1.500 .125 (38.10 3.18) rated power or rated voltage, % ambient temperature, c 100 80 60 40 20 0 25 75 125 175 225 275 for immediate engineering assistance in developing low ratio tc matched high voltage resistor sets, call or write our applications engineering and we will be pleased to offer the best solution from our high voltage resistor product capabilities. derating curve: dimensions in inches and (millimeters) design assistance in developing high voltage resistor sets with low tc tracking. ordering information : mg750 -100m - 1% model number: resistor value: tolerance mg 680 mg 712 mg 714 mg 715 mg 725 mg 720 mg 660 mg 716 mg 721 mg 745 mg 810 mg 815 mg 735 mg 730 mg 717 mg 785 mg 731 mg 740 most models are available with caddock's non-inductive serpentine pattern mg 650 mg 710 mg 750 mg 780 certain products shown in this catalog are covered by one or more patents, there are also patents pending. n non-inductive performance with caddock's exclusive design mg 655 type mg precision high voltage resistors page 2 of 2 sales and cor po rate of?

as 80 ppm/ c, combined with excellent long-term stability, and precision tolerances. 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%. ? typical extended life stability of 0.02% per 1,000 hours for standard resistance range as demonstrated by reliability testing. 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. page 1 of 2 sales and cor po rate of? ce 1717 chicago av e nue riverside, california 92507-2364 phone: (951) 788-1700 fax:
