EMI/RFI Filters (LC, RC Networks)

The EZA-CT20AAAJ is a device designed to limit electrical interference, which is generated by electrical and electronic equipment. It is used to protect electronic components, electrical equipment, and sensitive circuits against electromagnetic interference (EMI) and radio frequency interference (RFI).The EZA-CT20AAAJ is a filter that helps protect against disturbances that can cause malfunctioning of electronic circuits. It features low insertion loss, high pass/stop frequency attenuation, and high power handling capability.An EMI/RFI filter like the EZA-CT20AAAJ is a combination circuit made of various elements such as inductors, capacitors, and resistors, and operates like a high-pass, a low-pass, or a band-pass filter. A high-pass filter passes signals above its cut-off frequency, while a low-pass filter passes signals below its cut-off frequency. A band-pass filter passes signals at or near the center frequency of its design. The type of filter used depends on the type of signal that needs to be filtered out, and also what kinds of frequencies the filter can handle without introducing interference or degradation to the signal.Inductors are used to create a high-impedance (high-resistance) to high frequency signals, while capacitors provide a low-impedance to low frequency signals. Therefore, when used in combination, an LC filter can block (or reduce) both high and low frequency signals. Resistors are used to add the necessary resistive element to filter circuit.Another type of filter is the RC filter, which uses a combination of resistor and capacitor elements. This filter is ideal for blocking high frequency signals while allowing low frequency signals to pass.The EZA-CT20AAAJ is designed to be used in low voltage applications (up to 500V) and can be used in AC and DC current applications. It has a high-pass frequency of 1 MHz, a low-pass frequency of 30 MHz, and a maximum insertion loss of 0.2 dB. It also features two common-mode choke configurations that offer superior performance in EMI/RFI filtering applications.The EZA-CT20AAAJ is suitable in a variety of applications such as consumer electronics, automotive, industrial equipment, telecommunications, and medical instruments. It provides reliable EMI/RFI filtering performance that can help reduce the impact of disturbing frequencies and protect sensitive electronic equipment from hazardous interference.
