Name that part
« on: August 03, 2024, 08:49:39 pm »
Can someone tell me what these are?

I removed them frome something I scrapped but I don't remember what. At first glance they look luke a light bulb but there is no filament. I also know there was no need for light at their location on the board.

Marked 102 and 08E

Thanks

They look very well made for "lamps". Also, ...

I think they are most likely some form of gas-discharge (possibly neon) voltage stabliser/supressor.

I don't remember 100%, but I am thinking they are off the power supply board for a relatively newer (1080 era) sony projection TV.

I really don't think they were for an indicator because they were in the middle of other components just sitting on the board.

Neon bulbs need a driver/ballast to get them started, don't they?

No. Neon will conduct at 90 volts if I remember right. I think older fluorescent starters had neon elements and also some thermal contacts. If you are old enough, you will remember the two flashes of a fluorescent lamp before it was on.
