ELK-EA470FA Filters

EMI/RFI filters, specifically LC or RC networks, are electronic components that are designed to suppress or reduce electromagnetic interference (EMI) or radio-frequency interference (RFI). One particular type of EMI/RFI filter is the ELK-EA470FA, which has been designed to provide a cost-effective EMI/RFI interference solution for high-speed digital applications.

The ELK-EA470FA is a four-pole/eight-capacitor type of filter with a near-ideal peak current of 3 amps. It is designed to be used in systems where EMI/RFI interference could potentially disturb other system components, or even cause them to malfunction. The ELK-EA470FA is also capable of providing good common-mode and differential-mode noise rejection. It is available in a surface mount package or an 11-pin module.

The ELK-EA470FA can find applications in a variety of digital systems, such as peripheral devices, audio amplifiers, computers, mobile phones, and medical systems. It is also optimal for systems that are used in environments where there is high electromagnetic radiation, such as military grade systems. The filter works by absorbing and reflecting the electromagnetic waves that pass through it. This reflects the waves away, which causes the signal to be blocked and noise to be suppressed.

The ELK-EA470FA is designed with a low-ESR, low-loss structure that helps ensure consistently high performance. It has a high ripple current rating of up to 2.5 amps, and a high peak current of 3 amps. This makes it suitable for applications that are subject to short-term, rapid pulses of electrical current, such as high-speed digital systems.

The filter also has a high-frequency attenuation of up to 105 dB, which helps suppress and reject RFI/EMI noise. It is able to provide noise rejection in both the differential-mode and the common-mode, making it suitable for a wide range of applications. Additionally, the filter is RoHS compliant, making it eco-friendly and safe to use.

The ELK-EA470FA is designed with a small form factor, enabling it to fit into a variety of spaces. Its simple and compact design makes it easy to install and maintain. The filter is also resistant to temperature and humidity changes, ensuring consistent performance even in challenging environments. Additionally, its high-efficiency design allows it to operate without generating too much heat.

Overall, the ELK-EA470FA is an excellent EMI/RFI filter that is suitable for a variety of high-speed digital applications. It enables superior levels of noise rejection in both the differential and common mode, while its high-efficiency design and small form factor make it an ideal choice for applications where space is a major factor. Its reliable operation and cost-effective nature make it a great option for those looking for an effective EMI/RFI interference solution.
