线绕熔断电阻
熔断电阻器按电阻体使用材料可分为线绕式熔断电阻器和膜式熔断电阻器
1．线绕式熔断电阻器 线绕式熔断电阻器属于功率型涂覆型电阻器，其阻值较小，通常应用于工作电流较大的电路中。 在被保 护电路出现过电流故障时，电阻器的合金线部分将会因过热而烧断，对电路进行保护。
2．膜式熔断电阻器 膜式熔断电阻器是目前使用较多的熔断电阻器，它又分为碳膜熔断电阻器、金属膜熔断电阻器和金属氧化 膜熔断电阻器等多种。
RRX series fusible wire wound resistors are designed as fusible safety resistor (or, AC mains input resistors) in electric appliances and energy meters. The specially selected resistive winding wire and special non-flammable silicon cement coating material are adopted to ensure safe and silent fusing operation without flame and immediate interruption in overload conditions. Wide range of overload currents is available upon request.
The resistor fuses without explosion when AC mains voltage is applied. At the same time, it acts as an in-rush current limiting resistor for the normal operation.
The specially developed lacquer coating has superior thermal and electrical insulating properties. This allows designers to more easily meet the requirements of safety approval, whilst eliminating the need to put additional fuses in series with the input resistors.
Surge voltage capability: 2 kV (10Ω to 91Ω) and 4 kV (100 Ω) as per IEC 61000-4-5.
One grey code behind tolerance code is for distinguishing from the other kind of resistors with the same fire retardant coating.
The resistors are compliance with RoHS and REACH.
The resistors are compliance with Thunder Enterprise standard:
Q\SLC023-2011.
