Common Mode Chokes, also known as CM chokes, are devices used to suppress conducted or radiated electromagnetic interference (EMI) from electronic power systems. The RD7137-10-6M6 is a common mode choke designed for high frequency noise suppression in switching power supplies. They are typically used to suppress or block the passage of high frequency noise on lines and power cords and to meet EMC standards.

The RD7137-10-6M6 is an epoxy-filled, single-ended, common mode choke. It comes in a 6.3mm x 7mm standard package and is rated for 100℃ with a peak operating temperature of 150℃. It provides a high level of attenuation over a broad frequency range with excellent insertion loss and high common mode and differential mode noise rejection ratios. It has an inductance of 10µH ± 10% and an impedance of 18.8mΩ @ 400MHz.

The RD7137-10-6M6 is designed for use in consumer electronics, home appliances, computers, and industrial applications. It is well suited for high frequency noise suppression due to its attenuation capability and high current carrying capacity. Depending on the application, it can be used in conjunction with other components such as ferrite elbows, shunt capacitors, and power inductors. The product also has a low self-resonant frequency and excellent noise performance, making it ideal for high frequency applications.

The working principle of the RD7137-10-6M6 is based on the concept of mutual inductance. Mutual inductance is the phenomenon where two separate electric circuits or components interact with each other when solenoidal coils are in close proximity. It is the core principle behind choke/inductor designs such as the RD7137-10-6M6. In this case, when electrical energy is applied to the solenoidal coils, the system converts the alternating current into magnetic flux, and the magnetic flux produces a voltage in the opposite direction which opposes the current. This in effect reduces the high frequency noise.

The RD7137-10-6M6 is a versatile device that provides excellent performance for high frequency noise suppression applications. It offers a high level of attenuation over a broad frequency range, excellent insertion loss, and high common mode and differential mode noise rejection ratios. It is available in a standard 6.3mm x 7mm package and is rated for 100℃. The product is well suited for consumer electronics, home appliances, computers, and industrial applications and comes with an inductance of 10µH and a impedance of 18.8mΩ @ 400MHz. In addition, the RD7137-10-6M6 has a low self-resonant frequency and excellent noise performance, making it ideal for high frequency applications.
