RFI and EMI - Contacts, Fingerstocks, and Gaskets contain a variety of items which are used to help reduce or inhibit electromagnetic radiation interference (EMI) and radio-frequency interference (RFI) from entering, or exiting an electronic system or component. One such RFI and EMI-contacting, fingerstock and gasket item is the 4228PA51H01800, a specialty contact designed to reduce this type of electronic interference.

The 4228PA51H01800 is typically used to build a shield-capped system such as in a sealed switch or to create a path to divert EMI or RFI generated energy away from a circuit or component. It is made up of an EMI conductive fingerstock that functions as a gasket strip, and when compressed or constrained can create a continuous gasket while providing electrical contact between two separate components.

It is designed to be used with a circuit of any size, and can be soldered directly onto a printed circuit board via a reflow or wave solder process. The 4228PA51H01800 is highly versatile and is able to be used across a wide range of materials, including metals, plastics, or even other EMI-filtering materials.

As for its application field, the 4228PA51H01800 is most suitable for use in circuit filters, low inductance connections, RFI or EMI counteractant systems, shielded systems, and other similar products. It can reliably stand up to high temperatures, and identifies as UL and MIL-I-23053/4 listed. Typically, this product is used in telecommunications, computing, industrial control systems, consumer electronics, medical equipment, and other fields.

The working principle of the 4228PA51H01800 is partly derived from its design. The conductive fingerstock acts as a gasket strip when compressed or constrained, creating a continuous gasket along the entire contact area. This gasket helps divert EMI or RFI generated energy away from the circuit or part, in effect reducing or eliminating EMI or RFI noise. Additionally, this gasket strip also provides electrical contact between two separate components.

In conclusion, the 4228PA51H01800 is a specialty contact designed to reduce EMI and RFI emissions. Its designed application field consists of high temperature electronics, telecommunications, computing, industrial controls, consumer electronics, medical equipment, and similar products. The working principle is derived from the conductive fingerstock which helps to create a continuous gasket which not only diverts EMI/RFI generated energy away from a part, but also provides electrical contact between two separate components.
