EMI/RFI (electromagnetic interference/ radio frequency interference) filters are passive components used to protect an electronic device from the interference of external electromagnetic fields and digital noises. Depending on the nature of the interference, different types of EMI/RFI filters can be used.

Among the common types of EMI/RFI filters are the PEMI2STD/HP,115, which is a two-coil single-stage LC type filter. It combines both inductive and capacitive elements to create a low pass filter that is specially designed for suppressing common-mode noise. It is suited for applications where common-mode EMI noise suppression is needed, such as signal lines, power supplies, and data transmission.

When it comes to the application fields of PEMI2STD/HP,115, it has become widely used in electronic circuits for protection against noise on signal lines, power line noise interference, radio frequency interference (RFI), and the like. It is also used in dynamic electronic equipment to filter out powerline fluctuations. This type of filter can also be used to help reduce interference from high frequency signals such as cellular phones and radio transmitters.

The working principle of PEMI2STD/HP,115 is based upon inductive-capacitive coupling. This filter combines two windings – a primary winding and a secondary winding – which are connected in series. The two windings are each connected to one arm of a bridge circuit; however, their connection is not symmetrical. Due to this asymmetry, the filter creates a low-pass filter that helps attenuate common-mode interference.

The two windings of the filter are also connected to capacitors. This helps to bring down the high-frequency resonances. As both capacitors and inductors are connected, strong capacitive coupling between the two windings is achieved. This allows for the higher-frequency noise to be rejected, while the lower frequency noise is let through.

The PEMI2STD/HP,115 filter is an ideal solution for an environment where common-mode EMI noise reduction is required. Its performance is largely dependent on the components used and its overall design. In addition, the filter should be capable of providing adequate protection in areas where electromagnetic noise is present. This type of filter can be used in virtually any device or system, where noise induced by external electromagnetic fields must be minimized.
