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

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
