Common Mode Chokes can help diminish or suppress common mode interference. The RN122-1-02-27 is a common mode choke coil designed for noise interference attenuation from power lines in low voltage and high operating frequency applications. It helps to achieve compliance with EMI standards and reduce current leakage with its unique open design.

The RN122-1-02-27 has a built-in ferrite core, which allows it to more efficiently attenuate EMI noise. Its design also provides a wide variety of parameters, such as high inductance, low resistance, high temperature stability, and heat-resistant performance. The unique open design helps reduce the core ringing, achieving great performance in common mode noise suppression.

In terms of the application field, the RN122-1-02-27 can be used in various high-frequency AC and DC power supply circuits. It is suitable for common mode interference noise in low voltage applications, such as automotive electronics, household appliances, industrial control, and communications. Besides, it also can be used in battery-powered devices like notebooks, tablets, and portable medical equipment, etc.

Working principle wise, the RN122-1-02-27 adopts a two-wire type ferrite core along with enameled wire wound on the surface. The core works to limit the line current, while the enameled wire features high temperature insulation and good linearity for high frequency inductance. Specifically, the RN122-1-02-27\'s core can act as an inductor when AC current passed through it. This allows the coil to block common-mode noise from entering the input of the device, and also limits the propagation of such noise on the output side.

The RN122-1-02-27 is a very useful device when it comes to EMI noise suppression. It is able to provide better technical performance, greater durability, and even greater safety benefit to the products that use it. It can be used in a variety of electronic devices and will consistently help reduce the amount of interference that is present in electrical systems.
