Common Mode Chokes
Common mode (CM) chokes are a kind of electrical filter designed to reduce unnecessary interfaces by blocking high-frequency noise while allowing the desired signals to pass. Devices like inverters, motors, unshielded electronics, or unwanted signals are common mode noise current sources. CM chokes are essential to reduce such noise as this may cause electronic and electrical circuit problems.
Why are common mode chokes important?
Common mode chokes are indispensable tools to use as they help prevent electromagnetic interference (EMI) and radio frequency interface (RFI). These versatile devices help stop your electronic devices from malfunctioning and prevent them from causing problems during operation.
Factors necessary for CM choke selection:
Before you intend to buy a CM choke, it is crucial to consider the following criteria for your desired device. They include:
- Impedance (noise attenuation)
- Frequency bandwidth, and
- Current handling (amount of current needed to handle the CM choke)
What are the uses of common mode choke?
Common mode chokes have a wide range of applications in electrical, industrial, and telecommunication applications to help reduce or remove noise and electromagnetic interference. They can be found in:
- Industrial systems
- Professional audio systems
- Digital video camera
- Data storage systems
