Common Mode Chokes, like the RN212-0.8-02, are electromagnetic components designed for suppressing electrical interference within a circuit. Such interference, also known as a common mode, may be caused by external radiation or even the circuit itself, and if not adequately filtered can cause instability or even damage to equipment. Most commonly, common mode chokes are used in radio frequency (RF) and power applications, typically wireless systems or driver boards for motors and other appliances, where a smooth current supply is needed.

The RN212-0.8-02 is a common mode choke, rated for current up to 0.8A. It is designed to filter both high and virtually no noise levels, making it ideal for a range of applications. It also offers high attenuation in the frequency range of 150 kHz to 1GHz, making it effective in many different environments. The RN212-0.8-02 incorporates two layers of cores, enabling it to complete its job efficiently and with minimal attenuation.

When it comes to its working principle, the RN212-0.8-02 operates in a different manner than the standard common mode choke. This choke works by creating a magnetic flux via an alternating current (AC) field. This flux then interacts with the core of the choke, inducing a voltage in the windings, reducing the amount of interference in the form of signals, both high and low, passed on to the equipment or device. This process of filtering is known as ‘impedance matching’.

In terms of applications and where the RN212-0.8-02 is a suitable choice, this particular choke is ideal for RF applications including the filtering of high-frequency signals such as WiFi, Bluetooth, GPS, and even 4G mobile services. It can also be used in power applications such as motor drives, inverters, and portable electronics.

The RN212-0.8-02 is designed to operate in a range of temperatures, from -40°C up to 85°C. It is also UL listed and compliant with CE and RoHS regulations, so it can be used in virtually any environment. Additionally, its small size makes it perfect for use in circuits or boards where space is limited.

In terms of performance, the RN212-0.8-02 delivers high-level interference protection, with excellent attenuation in the frequency range of 150 kHz to 1GHz. The choke also provides high-current capability, allowing it to effectively filter large amounts of current.

To further enhance its performance, the RN212-0.8-02 is designed with two layers of cores, which can be used to increase the levels of attenuation. The choke also offers excellent thermal stability, allowing it to maintain its performance even at high temperatures.

Overall, the RN212-0.8-02 is an effective common mode choke, offering high-level interference protection in applications such as RF and power. It is designed for use in a range of temperatures, is UL-listed, and complies with CE and RoHS regulations. It offers high-attenuation in the frequency range of 150 kHz to 1GHz and two layers of cores, making it a great choice for any application that requires reliable common mode filtering.
