Introduction

EMI/RFI Filters, such as the 4202-036LF model, are electronic components used to decipher electronic signals. These filters are essential for providing protection from electromagnetic and radio frequency interference during the transmission of signals in a variety of applications. This article will discuss the application field and working principle of 4202-036LF.

Application Field of 4202-036LF

The 4202-036LF is a radial leaded RFI filter. This filter is rated for 120VAC input voltage, 600mA current, and 3KVac dielectric. As a result, this filter is used in many common power and signal line systems. These systems include LED lighting, automotive systems, robotics, handheld electronic applications, audio and video equipment, communication equipment, and instrumentation. The 4202-036LF also has a wide range of environmental specifications. This filter can successfully function even in extreme levels of humidity, temperature, shock, and vibration. Thus, this filter is often used in outdoor environments like construction sites, industrial plants, military training sites, and similar locations.

Working Principle Of 4202-036LF

The 4202-036LF filter works on the principle of pass/block capacitance. Essentially, this filter is designed to block levels of noise up to a certain frequency. It then passes on any signals above the specified frequency. The filter uses two distinct types of capacitors to achieve this effect. The first type of capacitor is the ‘blocking’ capacitor. This type blocks any signals that fall below the specified frequency. The blocking capacitor consists of an electrolytic capacitor that is relatively large. This capacitor blocks most of the noise at high frequencies and ensures that only signals that exceed the specified frequency reach the circuit. The second type of capacitor is the ‘passing’ capacitor. This type of capacitor allows the signals that are higher than the specified frequency to pass. The passing capacitor consists of a small ceramic capacitor that is connected in series with the other capacitor. This allows the filter to pass frequencies that exceed the specified frequency.

Conclusion

The 4202-036LF is a versatile RFI filter. This filter is ideal for applications requiring high levels of EMI and RFI protection. Furthermore, it has a wide variety of environmental specifications and a convenient radial lead design. Thus, the 4202-036LF can be used in a variety of applications and environments. Moreover, the 4202-036LF works on the principle of pass/block capacitance to block noise and pass signals of higher frequencies.
