MHR0307SA type High voltage reisistor 1. Feature 1. High resistance value : 1Mohm to 500Mohm 2. High operating voltage : Single Use 2.0kVdc max. Molded Use 3.0kVdc max. 3. Narrow tolerance : +/-0.5% till 100Mohm 4. High reliability resistor : Usage Original resistor material 2. GENERAL 2.1 Application This catalogue applies to the HIGH VOLTAGE RESISTOR used for High Voltage Power Supply. Please contact us before using in the application of any other products. 2.2 Standard atmospheric test conditions Unless otherwise specified, tests and measurements will be made under the standard conditions(Temperature : 535, relative humidity : 45%85%). If there may be any doubt on results, tests and measurements will be made under the following conditions, temperature : 25 +/- 2, relative humidity : 65% +/- 5%. If the test will be made under the special conditions, the measurememt will be made leaving under the standard conditions for 1 hour to 2 hours. 3.

Resistance value is single resistor value. 2. Resistance Value(R)rated voltage(E)rated power(P) will be calculated from the following formula. E = P X R But, rated voltage (E) is less than above value. For example : 0.3WX10M = 1.73kVDC (Maximum rated voltage) When the rated voltage exceeds the maximum rated voltage, the maximum rated voltage will be the rated voltage. 4.
