Product Description:
cement resistors are made by cut trimming metal oxide film core or winding resistance wires around non-alkaline ceramic core, either is added with a layer of heat and humidity resistant and non-corrosive protective material. The wire wound resistor or metal oxide resistor is then placed in a square ceramic package sealed with special nonflammable heat-resistant cement

Performance test:
| Test item | Test condition | performance |
| Temperature coefficient | Test the resistance value at normal temperature and normal temperature added 100ºC ,calculate per ºC resistance value change rate | ±300ppm/ºC |
| Short time overload | 1~4W: according 5 times rated power to account the voltage , 5~100W :according 10 times rated power to account the voltage or max overload voltage (get the lower) for 5 seconds | R≤±(2%Ro+0.05Ω) |
| Resistance to soldering heat | Immerge into 350±10ºC tin stove for 2~3 seconds | R≤±(1%Ro+0.05Ω) |
| solderability | Immerge into 260±5ºC tin stove for 2~3 seconds | The area of soldering is over 95% |
| Temperature cycling | At -55ºC for 30 minutes ,then at +25ºC for 10~15 minutes,then at +275ºC for 30 minutes ,then at +25ºC for 10~15 minutes,total 5 cycles | R≤±(1%Ro+0.05Ω) |
| Load life in humidity | Overload rated voltage or max working voltage (get the lower) for 1000hours (1.5 hours on and half-hour off) at the 40±2ºC and 90~95% relative humidity | R≤±(5%Ro+0.05Ω) |
| Load life in heat | Overload rated voltage or max working voltage (get the lower) for 1000 hours (1.5 hours on and half-hour off) at the 70±2ºC | R≤±(5%Ro+0.05Ω) |
| nonflammability | Respectively load ac voltage by 5,10,16 times rated power for 5 minutes | No visible flame |
