Appendix Description
- Thermal dissipation coefficient : Test method according to GB/T 6663.1. Measured at 850.1 (unless specified otherwise). Leads clamped 25mm 1.5mm from body. Tested in a test box (volume 1000 times thermistor volume) with static air at 255. Wiring ensures 75mm clearance from walls. High impedance voltmeter and ammeter accuracy >1%. Calculated using =(UTH ITH)/(Tb-25)mW/. Note: Results may vary due to equipment and environment.
- Thermal time constant : Test method according to GB/T 6663.1. Measured at Tb=(358.152)K, Ta=(298.152)K, and Ti (calculated: Ti:=Tb-(Tb-Ta)X0.632). Installation similar to test. Voltmeter/ammeter accuracy >1%, resistance meter accuracy 1%. Circuit involves closing contact AA to stabilize UTH/ITH within 60%-80% of zero power resistance at Tb. Closing contact BB starts timing until Ti temperature zero power resistance is reached.
- Maximum impulse capacitance Cmax: Capacitor CT 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 start temperature.
