Common Mode Chokes

Common Mode Chokes (CMC) are used in several applications, such as power electronics, industrial electronics, and medical electronics. UF1717VB-702Y0R3-01 is a type of CMC standardized by models of IEC 60938-1, IEC 60721, and IEC 61331. This module is designed to reject both common mode and differential mode interference in low-power electronic circuits. Basically, it has a very high inductance value, allowing it to easily reject signals with frequencies below the cut-off frequency.

Understanding UF1717VB-702Y0R3-01 Application Field and Working Principle

The UF1717VB-702Y0R3-01 CMC is typically used in applications requiring low voltage and low frequency. It has a wide inductance range between 7.5μH to 100μH, and can operate in temperatures up to +125°C. This module can be used in an EMI filter, an LED light, or a buck/boost converter application.

How Does UF1717VB-702Y0R3-01 Work?

UF1717VB-702Y0R3-01 works as a mixed type of core. It has a high permeability ferrite core that provides high inductance, and a low current rating of up to 2.5A. The module is designed to provide an effective isolation between a noisy source and a sensitive device, using the inductance of the core. This is done by limiting (or cutting off) the high frequency currents, allowing only the low frequency to pass through.

Advantages of UF1717VB-702Y0R3-01

The advantages of using UF1717VB-702Y0R3-01 include:

• High quality with good heat dissipation
• Wide inductance range (7.5μH to 100μH)
• Very reliable and efficient operation
• Low insertion losses with quick reset time
• Limited leakage currents
• High temperature stability
• Low Magnetic saturation

Conclusion

UF1717VB-702Y0R3-01 is a type of Common Mode Choke designed to efficiently isolate a noisy source from a sensitive device. It is typically used in applications which require low voltage and low frequency. This CMC offers high inductance, wide inductance range, and high temperature stability. Therefore, this type of CMC is suitable for many types of applications, such as EMI filters, LED lights, and buck/boost converters.
