Product Detail

        Carbon film resistors use a thin layer of carbon on top of an insulating rod which is cut to form a narrow, long resistive path.By controlling the length of the path and its width, the resistance can be precisely controlled with tolerances as tight as 1%. Overall, the capabilities of a carbon film resistor are better than a carbon composition resistor, with power ratings up to 5 watts and better stability. However, their frequency response is much worse due to the inductance and capacitance caused by the resistive path cut in to the film

.   

  Features:





1?Stable performance, extensive resistance, small size,high operating temperature and high ultimate voltage.

2? Highly adaptive pulse load, good high frequency performance.

3? Operating ambient temperature: -55?~+125?.

4? The resistor’s normal size coats yellow and the mini size coats brown.

5? Resistance tolerance:±2%?±5%?±10%.
