Description

Wire Wound Power Resistor / 0.25W - 10W RF Wire Wound Fuse Resistor



We also can make uncommon product per customers requirements.


Feature:

* Resistance range:0.01~33k ohm
* Power range: 1/4W ~ 10W
* Resistance tolerance: +/- 1% ~ +/- 10%
* Good heat-durability, low temperature coefficient, low noise, high overload power.
* Operating ambient temperature: -55C to +275C.
* Surface is nonflammable, the 1/4W-6W coating is gray white and indicate the resistance value by color ring, the 7W or over will indicate the resistance value by lettering or coating is green.

1, Good heat-durability. low temperature coefficient, low noise, high load power; nonflammability.
2, Can be Fusible during the stated time for protecting the circuit once wording at the required overload voltage.
3, Operating ambient temperatur: -55℃~+275℃.
4, the surface is gray white nonflammable coating and indicate white ring at the behind of the precision color ring.
5, Resistance tolerance:±1%, ±5%,±10%.

Performance Test:

Test Item Test Condition Performance
Temperature coefficient Test the resistance value at normal temperature and normal temperature added 100℃,calculate per℃ resistance value change rate . ±300ppm/℃
Short time overload 1/2~4W:According 5 times rated voltage, 5~10W:According 10 times rated power to account the voltage or Max.overload voltage (get the lower) for 5 seconds. ΔR≤±(2%R0+0.05Ω)
Pulse overload At 4 × rated voltage or Max. pulse overload voltage (get the lower) cycle 10000±200 times(1 second on, 25 seconds off ). ΔR≤±(1%R0+0.05Ω)
Resistance to soldering heat Immerge into 350±10℃ tin stove for 2~3 seconds. ΔR≤±(1%R0+0.05Ω)
Solderability Immerge into 245±3℃ tin stove for 2~3 seconds. The area of soldering is over 95%
Temperature cycling At -55℃ for 30 min, then at +25℃ for 10~15 min, then at +125℃ for 30 min, then at +25℃ for 10~15 min, total 5 cycles. ΔR≤±(1%R0+0.05Ω)
Load life in humidity Overload rated voltage or Max.working voltage (get the lower) for 1000 hours (1.5 hours on and half-hour off ) at the 40±2℃ and 90~95% relative humidity. ΔR≤±(5%R0+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±2℃. ΔR≤±(5%R0+0.05Ω)
Nonflammability Respectively load AC voltage by 5,10,16 times rared power for 5 minutes.
