SG140250D-48 can be classified into RFI and EMI - Contacts, Fingerstock and Gaskets. This type of RF inductor has a wide range of applications, from wireless communications and related systems, to antennas, passive components, and power supplies. Since inductors play an important role in many digital and RF signal processing activities, they are often used in circles of EMI/RFI shielding products.

The SG140250D-48 RF inductor is designed to support a wide variety of radio frequency applications. Its features include a compound wound design, which reduces losses due to eddy current effect. Thanks to this design, the inductor is capable of excellent temperature stability, and higher processing speed. It can be used in most broadcast frequency bands and can be used in both analog and digital systems. Thanks to its high power rating, it can also be used in high-current applications like cellular base-stations.

The working principle of the SG140250D-48 revolves around the Faraday Effect. This principle states that passing a magnetic field through a conductor generates induced current producing electromagnetic radiation. This radiation then has a frequency, which is used to control the frequency of the electromagnetic emissions. In this case, the SG140250D-48 harnesses the induced current and thereby, helps to reduce EMI/RFI radiation.

The SG140250D-48 is well suited for use as a RF contact or fingerstock. In contact applications, it functions as a relay or a contact punch. This allows a number of signals, to be sent or run in series, determined by the number of contacts used. In fingerstock applications, the SG140250D-48 shields against radiation egress, by providing a continuous circuit of low inductance. As opposed to an abrupt circuit break, this ensures lower-resistance to current flow and therefore, less interference is introduced.

The SG140250D-48 is also used in EMI/RFI gaskets and seals. It basically forms an EMI/RFI-impenetrable barrier between two components, which need to be grounded out. This seals off any sources of interference thoroughly, by making sure that the EMI/RFI energy does not pass through. It also helps to reduce crosstalk, and the formation of current loops.

All-in-all, the SG140250D-48 offers an effective way to reduce EMI/RFI emissions and noise, and can be used in various types of circuits. Thanks to its high power rating, it can be used for higher-current applications, and its compound wound design prevents losses due to eddy current effect. This means higher levels of performance and better noise reduction.
