General Data
- Nominal resistance allowable deviation: 5%, 10%
- Climate category: 55/155/21
- Low air pressure: 8.5kpa
- Stability grade: 5%
- Resistance change limit: Long-term test: (5%R+0.1); Short-term test: (1%R+0.05)

- Rated current: I(A) = P(W)/R()
- Derating curve is shown in Figure 2 (Rated power is the maximum value for continuous operation at 70. Power consumption is reduced according to the curve when exceeding 70).
- Fusing characteristic: Defined as the time required for the resistance to significantly increase and the current flowing through it to drop to below 1/50 of the initial test current when subjected to a specified overload. Fusing time is the time from the application of the specified overload until fusing occurs.

Impact Resistance Performance
According to Figure 3, by closing switch K1 and opening K2, repeatedly switch K1 ON/OFF for 2S ON and 2S OFF for 100 times. The test resistor should not become open-circuited.
Notes: 1. Capacitor C capacity is selected based on customer requirements. If no special requirements, C=10uF. 2. Resistor R value is selected based on the circuit used and converted to internal resistance. Resistor power is 20W, power factor is 0.8. Resistors below 10W generally use 20W, 5.1K (5%).
Main Test Items, Methods, and Performance Requirements
| Serial No. | Test Item | Test Method | Performance Requirements |
|---|---|---|---|
| 1 | Resistance | Measured by resistance error sorter. | Resistance value is within the nominal resistance and allowable deviation range. |
| 2 | Short-time Overload | Apply 2.5 times the rated voltage to the resistor for 5S, then measure resistance after 1-2h recovery and calculate the resistance change rate. | Resistance change: R(2%R+0.05) |
| 3 | Solderability | Dip the resistor leads into a solder pot at (2605) for 20.5S, with an immersion depth of 2+0/-0.5mm from the component body. Observe the solder coverage area after removal. | Surface circumference coverage of the immersed part is over 90%. |
| 4 | Withstand Voltage | Place the resistor in a metal "V" groove. Apply the specified insulation voltage between the connected resistor leads and the "V" groove for 60S. | No visible damage to the appearance, clear markings; no breakdown or arcing. |
