RFI and EMI - Contacts, Fingerstock and Gaskets

The 4078PA51H00450 is a contact that is classified as “fingerstock” which is part of a family of metallized contacts used for reducing both RFI and EMI within electronic devices. A fingerstock contact consists of a strip of conductive metal braid (usually made of copper but could be made of other metallic alloys as well) which is pre-formed in order to be soldered onto a printed circuit board. The main purpose of the contact is to provide an electrical connection between two components on the PCB.

The advantage of using fingerstocks for making electrical contacts is that they provide a low inductance connection because the contact itself acts as an inductive element. This in turn reduces RFI and EMI noise generated by the electrical connection. As a result, the contact is often used in electronic circuitry where RFI and EMI reduction is a priority such as in high speed bus connections, automotive applications, and medical equipments. In addition, these contacts are also used to reduce voltage drop at power supply bus and ground connections.

The 4078PA51H00450 contact offers a unique feature compared to other types of contacts- it has an integrated cutback. This cutback is used to reduce the amount of inductance in the connection which further reduces RFI and EMI noise. The contact is also designed so that it can easily be incorporated into printed circuit boards. The contact is easily solderable and its structure makes it resistant against oxidation. Finally, the contact is plated with a alloyed Ni-Pd base which makes it durable and corrosion-resistant.

In conclusion, the 4078PA51H00450 contact is an ideal choice for applications that require RFI and EMI reduction. Its integrated cutback provide a low inductance connection which reduces noise generated by the connection. Its structure makes the contact solderable and resistant against oxidation and corrosion, and its plating makes it durable. Therefore, it is an ideal choice for high speed bus connections, automotive applications, and medical equipments.
