Hello everyone! Recently I disassembled and old ADSL over POTS splitter and fould an component which was commented as 'GAS' I want to found out what component is this? Maybe someone knows :) Thanks. Have a good day ;) |

It’s a spark gap. Shorts out high voltages across the incoming lines. |

More specifically a GDT (gas discharge tube). These are available in various ratings, and usually used for lightning protection, which is a good idea for anything attached to long wires like telephone lines. :-+ Tim |

Wow thank you very much! I will read about it more. Everything that is on PCB or it is electronics interests me :) |
