Features:
- Carbon film has good uniformity and consistency, stable resistance, high reliability, great electrical property
- Change affected by temperature is very small, widely used in electronic devices
- Adjust the signal value in electric circuit
- In comparison measurement circuit, it can be used to read directly attenuation value of measured network
- Improved the impedance matching, if some circuit requires a relatively stable load impedance, an attenuator can be inserted between the circuit and actual load impedance, able to buffer impedance change
