General Data:
Main Test Items, Methods, and Performance Requirements:
| Item | Test Method | Performance Requirements |
|---|---|---|
| Resistance | Measured by resistance error sorter. | Resistance value within nominal resistance and allowable deviation. |
| Short-time Overload | Apply 2.5 times rated voltage for 5S, recover 1-2h, measure resistance, and calculate change rate. | Resistance change: R(2%R+0.05) |
| Solderability | Dip leads in solder pot (2605) for 20.5S, 2+0/-0.5mm from body. Observe coverage. | Over 90% surface coverage in circumferential direction of the dipped part. |
| Withstand Voltage | Apply specified insulation voltage between leads and metal 'V' groove for 60S. | No visible damage, clear marking; no breakdown, arcing. |
| Withstand Soldering Heat | Dip leads in solder pot (35010) for 3.50.5S, 2+0/-0.5mm from body. Recover 1h, measure resistance, calculate change rate. | Resistance change: R(1%R+0.05) |
| Rapid Temperature Change | 5 cycles of: -553 (30 min) -> Room temp (2-3 min) -> 1553 (30 min) -> Room temp (2-3 min). Recover 1-2h, measure resistance, calculate change rate. | Resistance change: R(1%R+0.05) |
| Endurance | Place in constant temperature chamber (703), apply rated DC voltage, cycle 1.5h on, 0.5h off for 1000h. Recover 1-4h, measure resistance, calculate change rate. | Resistance change: R(5%R+0.1) |
| Lead Strength | Tensile test: 10N for 10S. Bending test: 5N load, tilt ~90 for 2-3S, then bend 2 times in opposite direction. | Resistance change: R(1%R+0.05). |
| Vibration | Frequency 10-500Hz, amplitude 0.75mm or acceleration 98m/s (whichever is smaller). Vibration along Z, X, Y axes for 2h each, total 6h. Cycle 1min (10-55-10Hz). Measure resistance after test, calculate change rate. | 1) Appearance: No mechanical damage. 2) Resistance change: R(1%R+0.05) |
| Climatic Sequence | Dry heat -> Cyclic damp heat (Db) first cycle -> Cold -> Low pressure -> Cyclic damp heat (Db) remaining cycles -> DC load. | Resistance change: R(5%R+0.1). Insulation Resistance: 100M. |
| Accidental Overload | Apply 5, 10, 16 times rated power overload for 5min or until open circuit. Sample inside single-layer silk screen cylinder at 253mm from body. | Silk screen cylinder does not catch fire. |
