Widely used in electronic equipment to adjust the size of signals in the circuit.
In the comparison method measurement circuit, it can be used to directly read the attenuation value of the network under test.
Improve impedance matching. If some circuits require a relatively stable load impedance, an attenuator can be inserted between this circuit and the actual load impedance to buffer the impedance change.
Carbon film has good uniformity and consistency, stable resistance and high reliability.
Excellent electrical performance, minimal change due to temperature.
