PE-67531

Common Mode Chokes

PE-67531 is an EMI filter used to reduce high-frequency interference and enable communication devices to process signals accurately. It is a product of Murata Manufacturing, an electronic components manufacturer. PE-67531 is a common mode filter that can be used for both AC and DC applications. By combining core material and configuration, it has extremely high noise-suppression performance. It offers up to 13dB attenuation in 100MHz electromagnetic noise. It has a wide frequency range of 5MHz to 500MHz, and its permittivity is six times that of conventional monolithic products.

Application Field

PE-67531 can be used in high-frequency circuits for communication systems, including cellular phones, base stations, digital TVs, and navigation systems, which involve a variety of digital and analog communication components. It is often used for suppressing noise interference caused by mismatched communication lines in automobiles or industrial equipment. It is also used for interfaces for signal line noise suppression, as well as the control of noise interference in consumer electronics.

Working Principle

The PE-67531 is designed to operate by suppressing differential mode and common mode electromagnetic noise (EMI/EMC). It uses a carbon core and coil configuration to reduce themagnetic difference between the two lines and suppress common mode noise. An internal capacitor and coil configuration acts as an impedance matching network that prevents reflected and parasitic signals, which are referred to as "resonance." The core\'s magnetic shielding effect suppresses conduction-type noise. In addition, the overall design improves the filtering characteristics, providing improved noise suppression performance with low insertion loss.

The PE-67531 is also designed with a resonance suppression circuit, which combines an inductor and capacitor. This circuit helps to reduce the resonance effect, which occurs when a signal passes through multiple electrical paths. This reduces the likelihood of getting \'bumps\' in the signal, makes the signal more reliable, and lowers the noise level.

The PE-67531 also has an integrated thermal protection feature that helps protect against thermal overloads. This helps to prevent short circuits, which can occur when current passes through the filter, and helps to maintain a high level of safety. It also helps to reduce the power consumption of the filter, allowing it to be used in higher-powered applications.

Conclusion

PE-67531 is a Common Mode Chokes that is used to reduce high-frequency interference and enable communication devices to process signals accurately. It has a wide frequency range of 5MHz to 500MHz and can be used in a variety of applications. It has an integrated thermal protection feature as well as an internal capacitor and coil configuration, which act as an impedance matching network. With its high noise-suppression performance and reduced power consumption, the PE-67531 is a highly effective EMI filter for a variety of digital and analog communication components.
