| ITEM (STANDARD) | PERFORMANCE AND/OR QUALIITY ACCEPTANCE | TEST METHOD |
Resistance value Vs Temperature Characteristics | For RX∠100KΩ +350~-500PPM/ºC 100KΩ<=RX <=1MΩ 0~-700PPM/ºC 1 MΩ ∠ RX 0~-1500PPM/ºC | JIS-C-5202 5.2 Measure resistance (Ro ohm) at room Temperature(To ºC) Measure again the same at 100ºC Higher than room temperature R - RO 106 PPM = * RO (T0+100) -T0 |
Short time overload | The resistance variation shall be within±(0.75% + 0.05 ohm) and there Shall be no mechanical breakage | JIS-C-5202 5.5 Apply DC voltage 2.5times the rated Voltage for 5 seconds The leave at room temperature for 30 Minutes then measure MAX overload Voltage 0.50W - 700V (DC) |
Insulation resistance | 1000M ohm or more | JIS-C-5202 5.6 In V-BLOCK Lay the resistor on 90° angle metal V Block apply 100VDC between resistor Lead and V block for one Minute And Measure |
Voltage endurance | The resistance variation shall be within±(2% + 0.05ohm) and there shall be no mechanical breakage | JIS-C-5202 5.7 Icy the resistor on the 90° angle metal V Block and apply reamed AC voltage for One Minute. Test voltage 0.25W - 500V (AC) 0.50W -700V(AC) |
Intermittent overload | Resistance variation shall be Within ±(2.00% + 0.05ohm) | JIS-C-5202 5.8 Apply AC voltage 4 times the rated voltage for 1 second and rest for 25 seconds and Repeat this cycle for 10000±200times leave resistor 30 minutes at room temperature after test and measure Maximum voltage for intermittent Overload.0.50W-700V(AC) |
| Terminal strength | Resistance variation shall be within ±(0.5% + 0.05ohm) also there Shall be on mechanical breakage | Pull test: apply 2.5kg force to the lead in the direction of lead axislor30±5 seconds. |
Heat resistively Against soldering | Resistance variation shall be within ± (1.0%+0.05ohm) also there Shall be on mechanical breakage | JIS-C-5202 7.10 Dip the lead in to a solder bath having a Temperature of 350ºC ± 10ºC up to 4±0.8mm from the body of the resistor at room temperature 3 hours after ,then Measure |
Solder ability | More than 95% of the surface of the lead shall be covered by new solder after the leads are dipped in the Solder | JIS-C-5202 6.5 Dip the lead in to a solder bath having a Temperature of 260ºC±5ºC up to 4±0.8mm from the body of the resistor and hold it for 5 ± 0.5seconds then inspect |
Humidity load test | Resistance variation be Within ± (3.0% + 0.05ohm) Also there shall be mo mechanical breakage | JIS-C-5202 7.9 In temperature chamber having temperature 40ºC±2ºC,relative humidity 90 - 95%, Apply rated voltage 1.5hour and shut voltage 0.5 hour repeat this cycle for 1000 hours, leave in room temperature for lhour after test, then measure |
Load life test | The variation of the resistance Shall be within ± (3%+0.05ohm) Also there shall be no mechanical Breakage | JIS-C-5202 7.10 In the constant temperature chamber having Temperature70ºC ± 2ºC,apply rated Dc voltage for 1.5hour and shut voltage for 0.5 hour and repeat thin cycle for 1000 hours, leave in room temperature lhour after test, then measure |
