4420P-601-470/201

EMI/RFI filters are widely used electronic components to minimize electromagnetic and radio frequency interference that can cause damage to active components. The 4420P-601-470/201 EMI/RFI filter is an example of one of these interference mitigation tools. In this article, we\'ll explore the 4420P-601-470/201 application field and working principle.

What is the 4420P-601-470/201?

The 4420P-601-470/201 EMI/RFI filter is a low-pass filter made up of two capacitors and two inductors connected in series. It is designed to attenuate noise (electromagnetic interference or EMI) and radio frequency interference or (RFI) to protect active components from damage. The filter is made up of two components, an aluminum housing and an internal board. The two capacitors and two inductors on the board are mounted vertically, which helps reduce the size and profile of the filter.

Application Field

The 4420P-601-470/201 EMI/RFI filter is ideal for use in circuit boards and systems in a wide variety of industries, including automotive, telecommunications, and medical. The filter can be used for both EMI/RFI protection and signal filtering in a variety of applications and environments. These filters can be used to reduce the noise from power supplies, peripherals, embedded systems, and external disturbances.

The ultra-low-profile of the 4420P-601-470/201 makes it perfect for applications where space is limited or the filter must be tucked away to reduce the visibility of the filters. This makes the filter perfect for medical devices, automotive systems, and other applications where aesthetics and space are critical considerations.

Working Principle

The 4420P-601-470/201 EMI/RFI filter is made up of two capacitors and two inductors that are connected in series. These components form a low-pass filter, which restricts the amount of high-frequency noise that can pass through the filter. The filter can be used to reduce the amount of EMI and RFI noise, while also protecting active components from damage.

The two inductors are placed at the beginning of the filter, and the two capacitors are placed at the end of the filter. The capacitors block high-frequency noise, while the inductors absorb and dissipate low-frequency noise. The filter is designed to have a low insertion loss, which means that it does not significantly affect the power supply or signal transmission.

Conclusion

The 4420P-601-470/201 is a low-pass EMI/RFI filter designed to attenuate high-frequency noise and protect active components from damage. It is an ultra-low-profile filter that can be used in a wide variety of industries and applications, such as automotive, telecommunications, and medical. The filter is made up of two capacitors and two inductors connected in series, which form a low-pass filter that restricts high-frequency noise and protects against EMI/RFI.
