Performance Specification
| Characteristic | Limits | Test Method |
| Temperature Coefficient | Refer to TCR PPM/ in Resistance Range section | GB/T5729&JIS-C-5201&IEC60115-1 |
| Short-time overload | R/R (0.5%+0.05 ) | Permanent resistance change after the application of a potential of 2.5 times RCWV or Max.Overload Votage whichever less for 5 seconds. |
| Dielectric withstanding voltage | No evidence of flashover mechanical damage, arcing or insulation break down. | Resistors shall be clamped in the trough of a 90metallic v-block and shall be tested at ac potential respectively specified in the above list for 60-70 seconds. |
| Pulse overload | R/R (1%+0.05) | Resistance change after 10,000 cycles (1 second ON , 25 seconds OFF ) at 4 times RCWV of RCWV or Max.Overload whichever less. |
| Resistance to soldering heat | R/R (1%+0.05 ) | Permanent resistance change when leads immersed to a point 2.0- 2.5mm from the body in 2605 solder for 101 seconds. |
