EAP-20-101

IntroductionEAP-20-101 is part of the EAP series of Power Line Filter Modules, manufactured by EMI/RFI Specialty Company, Inc. The EAP-20-101 is a high performance power replacement module capable of providing high levels of protection against electromagnetic interference (EMI) and radio-frequency interference (RFI).Application FieldsThe EAP-20-101 power line filter module is most often used in industrial, residential, automotive, and military applications. The module can serve a variety of needs such as removing line noise from electric motors, suppressing power spikes, preventing interference from sensitive electronics, and attenuating high-voltage surge.Working PrincipleThe EAP-20-101 filter module is composed of complementary components such as capacitors, varistors, and inductors. It works by combining the capacitive and inductive components in parallel, in order to create a current path that divides the electric current into two separate frequency bands. This allows multiple frequencies to pass through the filter while suppressing unwanted frequencies outside the range.The capacitors form a low-pass filter that removes high-frequency harmonics and attenuates line noise, while the inductors form a high-pass filter that filters out low-frequency currents and prevents interference. The varistors attenuate surges and act as a shield against EMI/RFI.ConclusionThe EAP-20-101 power line filter module offers a high level of protection for sensitive electronics and protects connected systems from interference. The module is used in various applications such as residential, automotive, and industrial and serves a variety of needs such as removing line noise, attenuating surges, and preventing interference. Its unique design combines capacitors, varistors, and inductors which form two separate frequency bands, allowing multiple frequencies to pass while suppressing unwanted frequencies.
