In line rf choke
WebRadio Frequency choke or RF choke is the component used to block radio frequencies and to pass audio as well as DC frequencies. This is explained below with the equation. … WebA common mode choke is an electrical filter that blocks high frequency noise common to two or more data or power lines while allowing the desired DC or low-frequency signal to pass. Common mode (CM) noise current is typically radiated from sources such as unwanted radio signals, unshielded electronics, inverters and motors.
