ELECTRICAL CHARACTERISTICS Unless otherwise specified, all values are tested at the following condition: Temperature: 21℃ to 25℃; Relative humidity: 45% to 70% RJ**00R0000 is the part number of jumpers with resistance lower than 15mΩ. 6. DERATING CURVE For resistors working at an ambiance temperature of 70℃ or above, the power shall be derated in accordance with the curve. www.thunder-resistor.com sales@thunder-resistor.com Page 4 of 9 7. DIMENSION There are two kind of ceramic cores for RJ72, RJ73S and RJ74M so the tolerance of the dimension of these three type is 3mm instead of 1mm. The customer will get only one size products from the very beginning order and so on. The inner dimension of taping for type size could be adjusted upon the request of customers. www.thunder-resistor.com sales@thunder-resistor.com Page 5 of 9 8. ENVIRONMENTAL CHARACTERISTICS (1) Insulation Resistance IEC 60115-1, 4.6: in V-block for 60 seconds, the test resistance should be high than 10,000 M Ohm. (2) Dielectric Withstanding Voltage IEC 60115-1 4.7: Place resistors in V-block for 60 Seconds, no breakdown or flashover. (3) Temperature Coefficient Test IEC 60115-1, 4.8: Test of resistors at room temperature and 60°C or 100°C on request above room temperature. Then measure the resistance. The Temperature Coefficient is calculated by the following equation and its value should be within the range requested. Re sistor Temperature Coefficient  R R0 t t0 R  R0 1   10 6 R0 t  t0 = Resistance value under the testing temperature = Resistance value at the room temperature = the 2nd testing temperature = Room temperature (4) Short Time Overload Test IEC60115-1 4.13: At 2.5 times rated voltage or 2 times the maximum working voltage whichever is lower for 5 seconds, the resistor should be free from defects.
