EMI/RFI (electromagnetic interference/radio frequency interference) Filters are special circuits (like LC, RC Networks) that are used in electrical and electronic equipment to minimize the unwanted noises generated by such equipment. EMIF08-0402T16 is a type of EMI/RFI filter that features a low-cost design and superior shielding characteristics.

The EMIF08-0402T16 is designed for use in consumer electronics, industrial control systems, telecommunications, military and aerospace industries. This filter provides superior performance to reduce conducted and radiated interference at both signal and power levels. It has a wide frequency range from 500 KHz to 6 GHz, making it suitable for applications covering most the communication bands.

The EMIF08-0402T16 filter includes a choke inductor, a pair of capacitors, and a ferrite bead, all contained in a standard foot-print 0.04-inch in height. It has an operating temperature range of -40°C to +125°C. It is designed to handle high energy pulses caused by induced EMI or RFI from various sources, such as lightning, static discharges, high power switching, and electro-magnetic pulse (EMP).

The working principle of this filter is based on a combination of inductance, capacitance and resistance. The choke inductor is used to reduce conducted noise between two points in an electrical circuit. The capacitors are used to filter out high-frequency signals, while the ferrite beads act as “electrical noise absorbers” reducing noise in both the high and low frequency ranges. This combination of components helps to reduce the amount of interference from external sources as well as reducing the amount of noise generated by the equipment itself.

The EMIF08-0402T16 filter is a low-cost solution for reducing EMI/RFI interference in electrical and electronic systems. Its degree of interference reduction depends on the application, but has been demonstrated to be effective at managing most common types of EMI/RFI. The combination of components in a single package provides a compact, low-cost solution that is suitable for a wide range of applications.
