ICM0805ER181M Filters

Common mode chokes, also known as common mode inductors, are magnetic passive components used to suppress common mode noise in electronic circuits. With the growing demands for increasing processing power, shrinking size, and decreasing power consumption, common mode chokes shows the advantages because of its ability to reduce EMI without relying on costly filter components.

ICM0805ER181M Application Field

ICM0805ER181M\'s application field involves Entertainment equipment, Auto electronics, Home appliance, Network equipment, Lighting equipment and so on.It is designed to reduce electronic interference and protects sensitive circuits from contamination in high-poweror low-power communication circuits and systems. Due to its small size and low insertion loss, it is an ideal choice of common mode choke for these applications.

ICM0805ER181M Working Principle

The ICM0805ER181M is a common mode choke, which consists of a send-out coil and a receive-back coil. In this current configuration, the send-out coil works in the same direction and is used to transmit the data signals, while the receive-back coil functions to accept the transmitted signals. These two coils form a closed loop by passing the wireless signals. The received signals are then amplified and sent to the device. By using this magnetic isolation design, the ICM0805ER181M can effectively reduce the disturbance from other electronic devices and protect the critical circuitry from any damaging electrical noise.

The ICM0805ER181M uses the principle of inductive reactance to attenuate common mode signals and AC magnetic fields. The common mode chokes work by blocking the interference via the two coils. The front coil absorbs the interference signals to provide isolation while the back coil sends them out. This helps to prevent the interference signals from entering and engulfing the critical components in the device.

When a common mode signal passes through a choke, most of the signal is quickly redirected around the outside of the choke while a small amount of the signal is absorbed by the choke.

The ICM0805ER181M also has excellent common mode suppression of up to 30dB. It also offers low core loss and low magnetic leakage, allowing it to achieve high frequency transmission and greater efficiency.

In conclusion, the ICM0805ER181M common mode choke is used for suppressing common mode noise in a wide range of electronic circuits. It uses a closed loop signal transmission system which helps reduce EMI and protect the critical circuits from contamination. It also has excellent common mode suppression and low core loss and magnetic leakage, allowing it to support high frequency transmission.
