SSHB21H-R06825

Common mode chokes are widely used in industrialsystems for various purposes, such as separating out high-frequency interference signals, improving power line stability, reducing crosstalk, and more. One of the most common common mode chokes is the SSHB21H-R06825 – a two-terminal device which can be connected between a power source and a load for common mode noise suppression. In this article, we will take a look at the applications and working principle of the SSHB21H-R06825.

Applications

The SSHB21H-R06825 is an excellent choice for common mode filter applications in various systems. It can be used in automotive, industrial, home appliance, and power systems for reducing common mode noise between components. Furthermore, the SSHB21H-R06825 is suitable for use in high-speed data transmission systems such as Ethernet, USB, Fibre Optics, and more. It is also suitable for high-power applications such as lighting and home entertainment systems.

The SSHB21H-R06825 is designed with high surge capability and has a wide temperature capability. It can operate from -55°C to +125°C and can manage up to 80A peak surge current. It has a built-in temperature-compensated varistor for overvoltage protection as well as a reverse-sentinel feature that prevents potential EMI (electromagnetic interference) during unlock. This makes the SSHB21H-R06825 a reliable and efficient device for common mode filtering applications.

Working Principle

The SSHB21H-R06825 works by using the principle of inductance. This means that when an alternating current passes through the device, it causes a magnetic field to be induced around it. This magnetic field interacts with the signal passing through the device and creates a phase shift. The magnitude of the phase shift is dependent on the inductance of the device. This allows the device to reject common mode noise and reduce both radiated and conducted emissions.

The inductance of the SSHB21H-R06825 is designed to be higher than that of other common mode chokes. This helps to ensure that it is able to reduce common mode interference to an even greater degree. Additionally, the device features two diverging common mode cores which reduces the amount of “leakage” and further improves noise reduction.

Conclusion

The SSHB21H-R06825 is an effective and reliable common mode choke which is suitable for many applications. It is designed with a high inductance and two diverging cores for maximum efficiency and noise reduction. Furthermore, the device has a wide temperature range, high surge capability, and a built-in temperature-compensated varistor for overvoltage protection. All of these features make the SSHB21H-R06825 an ideal solution for common mode noise suppression.
