Have you heard of communications transformers? Do you want to know about it? This article will introduce communication transformers.

About the definition of communication transformer.
In telephone terminal circuits and trunk line product lines, transformers that regulate the quality and status of communication circuits.

telephone lines

Communication transformer product features:
1. The communication transformer has a metal shell for heat dissipation. Suitable for heat sink installation.
2. Various wiring methods. Easy to install tightly and attach radiator.
3. Small size and large power load.
4. Good weather resistance, vibration resistance and safety. Suitable for various harsh working environments
5. Made of special materials. Good insulation, safe and reliable.

Communication transformer application:
Communication transformer products are extensive.
Can apply it to network communication equipment. For example: 
Network cards, cable modems, xDSL high-speed communication devices, hubs, switches, fiber optic receivers and transmitters, routers, embedded systems, and Voice over IP, among others.
En plus de l'équipement de communication de données, l'équipement de transmission photoélectrique, l'équipement de réseau d'accès, l'équipement Internet de ligne électrique, l'équipement vocal, etc.

Instructions for using communication transformers:
When we apply transformers in communication lines, we must add capacitor components to isolate DC. If DC current passes through the coil of the transformer, magnetic saturation will occur. This will cause it to lose its original technical indicators.
At the same time, the DC impedance of the transformer windings is also low. This in turn affects the status of the communication line. When applying it to normal telephone lines. You can consider adding a capacitor with a capacity of no less than 1uF and a withstand voltage of no less than 63V.
If you do not confirm the DC polarity of the circuit. Do not use electrolytic capacitor components with polarity.
If you use a power amplifier such as an LM386 to drive a transformer. Please consider adding a 600-2K ohm resistor. At the same time, add back-to-back 4.7V voltage regulator tubes to its winding. This avoids overvoltage damage.

The above is all about what we want to introduce about communication transformers!
