4220PA51G09600 RF/IF and RFID

RFI and EMI - Contacts, Fingerstock and Gaskets

4220PA51G09600 is an engineering grade, piezoelectric piezoceramic material with the same dielectric permittivity as quartz, and making it ideal for applications in the radio frequency interference (RFI) and electromagnetic interference (EMI) industries. It is constructed from a textured lead-free ceramic substrate and printing ink. This combination results in an extremely high-performance, cost-effective ceramic insulation that can be reused multiple times and will hold up under commercial and industrial settings.

This material is used in contact pieces, fingerstock, and gaskets that are ideal for making RF and EMI screens, high-precision parts, MEMS assemblies, and other sensitive and critical parts. The contact pieces are designed to protection against loss of electrical energy, and can replace the costlier and more traditional copper or aluminum contacts. Fingerstock is available in a range of sizes and ratings, and is also designed to provide a secure, high-performance connection between two surfaces. Gaskets are designed to provide a tight seal between two parts, while ensuring that any previous EMI shocks are prevented from escaping.

The working principle is based on the piezoelectric effect, where an electric field is placed across the material and causes it to vibrate. The vibration of the material is then converted into electrical energy, which can be used to protect against EMI radiation. The piezoelectric effect also provides the material with the ability to transmit electrical signals efficiently from one part of the device to another. As a result, it is often used in high-frequency communication devices, such as radios and mobile phones.

The material is also resistant to extreme temperatures and humidity, making it a suitable material for use in harsh weather conditions. It also offers excellent vibration absorption and isolation characteristics, allowing it to effectively protect components from shock, vibration, and electromagnetic interference. Its ability to absorb shocks makes it ideal for use in sensitive parts, such as MEMS devices or other electronics components. The material ensures that these parts are not subjected to damage or malfunction due to external shocks or vibrations.

4220PA51G09600 is one of the most versatile materials for use in RF and EMI components. Its properties make it an ideal choice for shielding components from RFI and EMI radiation, as well as providing superior vibration absorption and insulation characteristics. Its cost-effectiveness, high performance, and long-term reliability make it an invaluable material for the electronics industry.
