Appendix: Testing Method Details
| Parameter | Testing Method Description |
|---|---|
| Thermal dissipation coefficient | Refer to GB/T 6663.1. Measure zero power resistance at temperature Tb (typically 850.1). Clamp leads at 25mm 1.5mm from body using a fixture. Place in a test box (volume 1000x thermistor volume) with air static at 255. Ensure 75mm distance from walls. Connect test circuit with high impedance voltmeter and ammeter (accuracy >1%). Adjust current ITH until UTH/ITH is within 5% of zero power resistance at Tb. Calculate =(UTH ITH)/(Tb-25)mW/. Note: Results can vary due to testing environment and methods. |
| Thermal time constant | Refer to GB/T 6663.1. Measure zero power resistance at Tb=(358.152)K, Ta=(298.152)K, and Ti (calculated as Ti:=Tb-(Tb-Ta)X0.632). Installation method is same as for . Use high impedance voltmeter and ammeter (accuracy >1%), resistance meter (accuracy 1%). Close contact AA, adjust ITH until UTH/ITH is 60%-80% of zero power resistance at Tb. Close contact BB to start timing when thermistor reaches zero power resistance at Tb, and stop timing at Ti temperature zero power resistance. The time elapsed is the thermal time constant. |
| Maximum impulse capacitance Cmax | Capacitor CT is discharged through a series fixed resistor and thermistor. Charging voltage is 180/375 V, corresponding to (110/230+U)2. Capacitor undergoes 1000 discharge cycles. Test environment temperature between 15 and 35, maintained within 2 of starting temperature. |
