What Is The Purpose Of A Capacitor In A Telephone Socket

The gtnc 4 rtshk iv is a gtn 4 socket that has an additional circuit. Extending the line from the master socket to an extension socket has a basic requirement of 3 wires pins 2 5 and 3.

The capacitor enables phones that have their bell circuit wired with one.

What is the purpose of a capacitor in a telephone socket. The lack of a capacitor usually indicates you are not connected to the master socket. The metal pins are machined rather than stamped so they are a bit more expensive than most standard sockets. The resistor is used for line test facilities when there is no phone.

I am sure that be broadband support or one of their support forums should be able to help you. This arrangement is called snubber circuit. Phone line with no ring capacitor.

The major purpose of a capacitor. The capacitor in the circuit stops the dc in to pass through the bell coil but it lets the ring voltage through easily. It surpasses voltage spikes that would be dangerous for the sensitive electronics circuits.

It should not affect your broadband. The pins can be purchased either as individual metal pins for low profile flush mounting on a printed circuit board or as a strip of pins held together by a plastic body much like a single row socket. In ac system is power factor correction providing sufficient amount of starting torque to single phase motors reactive power compensation used as a source of reactive power in stand alone wind energy system in snubber circuits of high voltage rating switches for suppressing voltage spikes during switching etc.

The circut consists of the bell coil and a capacitor usually 470 nf to 2 uf rated for 250v or more in series with it. The dc circuit on the origional phones was to indicate oh hook and off hook and power the carbon button mirophones. As name implies it is kind of shock absorber for the electrical circuits.

This circuit is connected in parallel to other telephone electronics. Connected to the master socket you will not need this. In a true master socket you have a ring capacitor to pass ac ring current to the ringer of standard phones the cap passes ac but crucially blocks the constant dc on the line otherwise your phone would rinnnnnnnnnngggggg constantly.

If your phone line is fine then you will have to discuss broadband issue with be. The 5th plastic pin of the inserted plug disconnects a 1 mf capacitor that otherwise closes the circuit of the telephone line when the plug is not inserted. Voltage spikes gets generated due to.

This feature allows testing the line when the phone is not plugged in. The capacitor blocks dc while passing the audio and ring signals. The line is fed to pins 2 5 and the ring capacitor to pin 3 the 470k resistor helping to charge the capacitor to line voltage to stop ring blips when plugging in a telephone.

Leg on pin 3 to work.
