There are various types of sockets, including DC sockets, headphone sockets, USB sockets, RJ45 sockets, etc. There are many types and functions of sockets available for us to use and purchase. Today we will mainly talk about the specifications of 3.5mm headphone sockets, in order to know how to use them correctly during work. We have also introduced the relevant knowledge of 3.5mm headphone sockets in previous articles. Now we will briefly understand their specific specifications. The detailed content is as follows:

Everyone has a certain understanding of the structure of the 3.5mm headphone jack, which has a different high fidelity design for 5.1 channels and various audio frequencies. It has multiple functional options and can be used in various forms, including DIP and SMT. The contact terminals are designed with elastic structures to ensure good and stable contact throughout their service life. The welding temperature is 260 ± 5 ℃ for 10S, the insertion and removal force is 3-20N, and the lifespan is 5000 times. For headphones sockets made of a certain material, it is usually said that the acceptable current density is not the current intensity. Due to different thicknesses of wires, the acceptable current intensity varies.

The 3.5mm headphone socket is generally represented by "L" followed by a number in the circuit, for example: L6 represents the inductor numbered 6. Inductive coils are made by winding insulated wires on an insulated skeleton for a certain number of turns. DC can pass through the coil, and the DC resistance is the resistance of the wire itself, with a very small voltage drop; The 3.5mm headphone jack is mainly used for various digital voice information terminals such as DVD players, CD players, wireless phones, MP3 players, mobile phone 3D design, learning machines, digital cameras, etc.
