Common Mode Chokes

Common mode chokes, also known as common mode inductors, are electrical components used to prevent or reduce distortion from interference signals in a circuit. They work by creating a magnetic field around the wire, blocking any external signals from getting through. Common mode choke applications are used to reduce low-frequency electromagnetic interference (EMI) from entering the circuit in areas where there is high noise, such as communication equipment, power tools, and medical equipment. The CMF23H-153191-B is a common mode choke that is designed for dampening high-frequency (HF) signals.

CMF23H-153191-B Application Field

The CMF23H-153191-B is primarily used in electro-magnetic compatibility (EMC) applications. It is designed to reduce the radiated energy caused by high-frequency emissions, and can be used to protect both communication and control circuits. The choke is suitable for use in applications such as automotive, medical, industrial, and telecom systems. In addition, it can be used for applications such as switching power supplies, inverters, and home appliances, where a high degree of input/output (I/O) isolation is needed.

CMF23H-153191-B Working Principle

The working principle of the CMF23H-153191-B common mode choke is to absorb the high-frequency signals that enter the circuit. This is accomplished by using a ferrite core that creates a magnetic field around the wire and allows the high-frequency signals to be blocked or absorbed. The core also helps to block any unwanted signals from getting into the system. This helps to reduce radiated emissions and interference that could cause damage to other components in the circuit.

The choke has a common mode impedance of 1kΩ to 10kΩ and a differential mode impedance of 0.1ω to 0.75ω. It is rated for up to 100Vrms and operates over a frequency range of 10-300 MHz. The CMF23H-153191-B is designed to handle currents up to 1 A with a peak voltage of 350 V. It is rated for temperatures from -55°C to +125°C. It also meets the requirements of MIL-STD 8805 standards.

The CMF23H-153191-B common mode choke is a reliable and effective way to reduce high-frequency emissions and protect circuits from interference. It is a cost-effective solution for EMC applications and can be used in many different applications. The efficient design and rugged construction make the choke ideal for use in a variety of environments.
