Common Mode Chokes are vital components for power electronic equipment that attach to the power line to ensure the protection of ground connections, to block the flow of AC current, and to limit harmonic noise and potential surges. The RN112-0.5-02 is a type of Common Mode Choke used for EMC/EMI applications. It is designed to reduce common-mode noise levels on power and data lines and offer electrical and magnetic shielding for digital and analog circuits.

The RN112-0.5-02 is suitable for applications such as switch-mode power supplies, inverters, motor drives, servos, Programmable Logic Controllers (PLCs) and microcontrollers. It provides high-frequency insulation of up to 1GHz and good common-mode noise suppression performance up to f=1kHz. The RN112-0.5-02 is composed of a ferrite core, and is molded with an epoxy coating. It is RoHS compliant and has a rated current of 0.5A and a rated voltage of 50V AC/DC.

The working principle behind the RN112-0.5-02 Common Mode Choke is based on the concept of a transformer. When AC power passes through the core, it generates a magnetic field which induces a voltage on the other two secondary windings. This voltage is added to the original AC voltage (common-mode voltage) and reduces the added noise in the signal lines.

In order to reduce common-mode noise, the RN112-0.5-02 uses two capacitors placed in parallel with the core, which serve as high frequency bypass capacitors. This allows the impedance between the high and low frequencies to be consistent, which further reduces the amount of common mode noise. The capacitors also have an inherent amount of impedance, which helps to limit harmonic noise in the power and data lines.

The RN112-0.5-02 is an ideal solution for noise suppression and line protection. It provides protection against both EMI/EMC and power transients. Furthermore, its small size and low cost make it a great solution for applications that require a simple and efficient noise reduction solution. Its high-frequency insulation and low common-mode noise suppression performance make it a versatile EMI/EMC solution for various applications.
