Sockets for ICs, Transistors

When it comes to the industrial automation, electrical and electronics components, sockets for ICs and transistors serve an important role. With the help of a socket, the components are safely and securely mounted, connected, and replaced, and thus allow hassle-free assembly, testing, and troubleshooting work. One example of a very popular and widely used socket is the 40-3553-18 socket.

Application Field

The 40-3553-18 socket is designed for TO-92 packaged transistors and ICs that have a 0.10" wide base. It works with many different transistor part numbers, including 2N2222, 2N3904, 2N3906, BC546, BC547, BC548, BC549, 2SC945, and MPS2222A. A wide variety of industrial and consumer electronics applications benefit from the use of these sockets including clothes irons, hair dryers, air conditioning systems, car audio systems, and many more.

Working Principle

The 40-3553-18 sockets use two columns of spring-loaded pins to make contact with the IC or transistor. This ensures reliable electrical connections and allows for easy removal of the components without damaging them. The socket itself is made of a durable material such as plastic or epoxy. It has a lead configuration of in-line with two leads, making the socket suitable for use in an through-hole mounting application. The socket connection uses an insulation displacement connection (IDC) with a minimum of 0.20mm wire gauge and a maximum of 1.22mm wire gauge.

The socket has an operating temperature range from -40 to +105℃ and a current rating of up to 2A per pin. It is also capable of a peak voltage of 30VAC/30VDC for a maximum power rating of 9.3W. Furthermore, the 40-3553-18 socket has a UL 94V-0 flammability rating, meaning it provides excellent protection from fire and other external hazards.

Conclusion

The 40-3553-18 socket is an extremely popular and reliable socket for TO-92 packaged transistors and ICs. It has a wide range of applications and is able to make reliable electrical connections with ease. With its low operating temperature, low power rating, and high current rating, the 40-3553-18 socket certainly stands out from the many other sockets available on the market. The affordability and reliability that it offers can make it a great choice for many industrial and consumer applications.
