Common Mode Chokes

Common mode chokes (CMCs) are specially designed components that are used to control the movement of electromagnetic fields in electronic and electrical circuits. CMCs are widely used in various applications, such as power supplies, data converters, and motor control circuits. The most popular type of CMC is the ICM0805ER261M.

Overview

The ICM0805ER261M is a high-frequency CMC with high current and low inductance. It is designed to limit high frequency electrical noise that can affect the performance of the circuit. The ICM0805ER261M is capable of reducing common-mode noise up to 50 dB, making it an ideal choice for applications that must meet higher-frequency noise requirements. The device operates at temperatures from -40 to +125°C and can handle up to 16 A of current. It is capable of suppressing both common-mode interference and conducted noise.

Application Field

The ICM0805ER261M CMC is used in a variety of applications, including the following:

• Power supplies
• Data converters
• Motor control circuits
• Telecommunication systems
• Industrial equipment
• Audio and video equipment
• Security systems
• Aerospace and automotive electronics

The ICM0805ER261M CMC is ideal for power supply and motor control applications, due to its high current handling capability and low inductance. Furthermore, its wide operating temperature range enables it to be used in harsh environments.

Working Principle

Common mode chokes work by providing a low-impedance path to high-frequency current and a high-impedance path to low-frequency current, thus limiting the effects that high-frequency noise can have on the operation of the circuit. The ICM0805ER261M CMC is designed to provide a high attenuation of common-mode interference within the frequency range of 100 kHz to 1 MHz, making it effective in reducing noise in high-frequency applications.The ICM0805ER261M CMC is composed of two separate inductors, which are connected in series. The two inductors act as a low-pass filter, allowing only small amounts of high-frequency noise to pass through the device. The device also has a built-in capacitor, which helps to further limit the effects of high-frequency noise. The ICM0805ER261M CMC is capable of providing high levels of attenuation over a wide frequency range, making it an effective solution for reducing noise in applications such as power supplies, data converters, and motor control circuits.
