Performance Test

 

         1. Test Condition
A standard test condition is performed under ambient temperature 20±2ºC
Test can be performed under temperature 10 to 35ºC and R.H 45 to 85%
         2. Short time overload  JIS-C-5202 5.5
Apply 2.5 times of rated voltage (If the voltage exceeds the maximum
Overload voltage, the maximum overload voltage will be used as the rated
Voltage.) On the resistor for 5 seconds. Then measure the resistance value
after the resistor is released of load for 30 minutes. The resistance value
changed percent should be within ±1.00%+0.05 Ohm).
         3.Load Life  JIS-C-5202 7.10
Placed in the temperature chamber of 70±2ºC the resistors shall be
Connected to the lead wire at the point of 25 mm . Length with each terminal,
The resistors shall be arranged not much effected mutually by the
Temperature of the resistors and the excessive ventilation shall not be Performed , for 90 minutes ON and 30 minutes OFF under this condition The rated D.C. voltage is applied continuously for 1,000 ±12hours , then leaving in room temperature at no-load for 1 hour.
 The resistance value changed percent shall be within ±(5.00%+0.05 Ohm) as compared
With the value before the test .
         4.Moisture Resistance Load Life    JIS-C-5202 7.9
The resistor will be placed in the constant temperature chamber of 40±
2ºC at the R.H. 90 to 95% . Then repeatedly to applied rated voltage 90
Minutes ON and 30 minutes OFF for a total 500 hours . The resistance
Value will be measured after the test and leaving in room temperature for 1 hour
The resistance value changed percent shall be within ±(5.00%+0.05 Ohm)
And there shall be no remarkable changed in appearance and any mechanical Damage .                                                      
        5. Effective Soldering    JIS-C-5202 7.10
The terminal lead wire shall be dipped into molten solder of 350±10ºC for 3±0.5 seconds
up to 3.2 to 4.8 mm. From the body of resistor . Then the resistors is left in the room temperature for 3 hours . The resistance value changed percent shall be within ±(1%+0.05 Ohm) as compared with the value before the test and no remarkable changed in appearance or mechanical damage should be observed .
         6.Temperature Coefficient Test  JIS-C-5202 5.2
Test resistor above room temperature 40ºC~60ºC (Testing Temp.) at a  Constant temperature
oven for 30~40 minutes . Then measure the resistance The Temperature Coefficient can be calculated by the falling equation  and the value shall be within range of Table 1 .
 

0.1Ω<=Rx <10Ω	-200~+200ppm/ºC
10Ω<=Rx <120kΩ	-350~+350ppm/ºC

            R₁:Resistance value under the temperature .
            R₂:Resistance value at the room temperature
            T₁:The testing temperature .
            T₂:Room temperature .                                                                                                                                                                          
         7. Dielectric Withstanding Voltage    JIS-C-5202 5.7
The resistor is placed on the metal V block. A. terminals connected
Together with the block for about 60 seconds . The resistor shall be able
To withstand the voltage without any sign of a breakdown or flashover .
