A leading resistors manufacturing company, Pakheng, can supply High Power Ceramic Tube Resistors Wire Wound Waved Shape Fixed Type Through Hole 20 Watt 150ohm with Non-inductive Function with original of Shenzhen China. We devoted ourselves to resistors research 25 years. Covering most of Europe and America market. We are also can supply film resistors and wire-wound resistors, having our group of professional personnel at your service.
Two terminal extensions are fixed on both ends of a ceramic tube on whose surface winds wave-shaped resistance alloy wire, and a high temperature-resistant and fireproof coating are applied.The ceramic tube can function as resistance wire skeleton and heat radiator as well. This product can be customized to special needs of customers and applicable to simulation load test, equipment discharging, automatic control and inverter's energy loss brake.
Construction of High Power Ceramic Tube Resistors
1.A tubular ceramic has two terminals, and is wound with copper wire or chromium alloy wire to provide the resistance and then coated with high temperature ,non-flammable resin.
2.After the semi-finished resistor is cool and dry,insulation is applied through a temperature process and then the mounts are attached.
Specification and Dimension
Test the resistance value at normal temperature and normal temperature added 100℃,calculate per℃ resistance value change rate .
Short time overload
2.5 × rated voltage or Max.overload voltage (get the lower) for 5 seconds.
Resistance to soldering heat
Immerge into 350±10℃ tin stove for 2~3 seconds.
Immerge into 245±3℃ tin stove for 2~3 seconds.
The area of soldering is over 95%
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.
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.
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℃.
