ACH4518-222-TD01 Application Field and Working Principle
EMI/RFI filters, also known as LC, RC networks or simply LC/RC filters, are electronic filters that are used in the design of electrical circuits. These filters are used to limit the amount of unwanted electrical noise that can be present in an electrical circuit, due to electromagnetic interference or radio frequency interference. In many cases, this noise is generated from other components or devices located nearby, and can harm the performance of the circuit if it is not controlled or properly filtered.The ACH4518-222-TD01 EMI/RFI filter is a compact filter module designed to meet commercial, MIL-STD and MIL-SPEC standards and requirements. It has a low profile design with a height of 2.2 mm and a temperature range of - 40°C to + 130°C. The filter has a 2-pin connector for easy installation and removal, and the filter is designed to provide excellent EMI/RFI suppression.This filter is designed to be used in a variety of applications, such as medical electronics, avionics, industrial electronics, and automobile electronics. It is designed for use in applications that require both low-pass and high-pass filtering. The filter consists of three parts: a low-pass filter, a high-pass filter, and a combination filter. The low-pass filter is designed to reject lower frequency signals, while the high-pass filter is designed to reject higher frequency signals. The combination filter is designed to reject both low and high frequency noise.This filter design is based on capacitors, inductors, and resistors. The capacitor is used to store electrical energy and also acts as a noise reducer. The inductor is used to create a magnetic field, which helps to further reduce any unwanted noise. The resistor is used to control the flow of current and to ensure the filter does not become overloaded or cause any distortions.When the filter is installed in a circuit, it will help to reduce the level of unwanted noise that could potentially be present. It also helps to protect the circuit from being overloaded or damaged due to the presence of too much noise.Overall, the ACH4518-222-TD01 EMI/RFI filter is a reliable and effective solution for suppressing noise in a variety of circuits. It is a cost-effective way to reduce the unwanted noise present in a circuit. As such, it is a great choice for many types of applications.
