Guess that Part! (mystery part #2 is up)

Ok, I have here a part I've only come across once. Their magnetic and will attach themselves to metal. the top says 9143 with an arrow pointing left. Here's some pics to visually see what I'm talking about.





Any thoughts on what they are? They came out of an AT power supply but I've yet to see anymore from other AT power supplies.

Here's all I found in a quick search.

Basic function: The power supplies are used for the intrinsically safe operation of field devices e.g. 3- or 4-wire transmitters, solenoid valves, light barriers, controllers and more.

I'm going with the and more . Interesting

Some sort of Diode??

It is a copper wrapped ferrite choke, the arrow probably denotes the negative terminal. Wiki calls them inductors.

A variety of types of ferrite core inductors and transformers

" Inductors are widely used in alternating current (AC) electronic equipment, particularly in radio equipment. They are used to block the flow of AC current while allowing DC to pass; inductors designed for this purpose are called chokes. They are also used in electronic filters to separate signals of different frequencies, and in combination with capacitors to make tuned circuits, used to tune radio and TV receivers."

I don't know. The numbers on top is the info you seek but you have to know how to read them. The little stuff I worked on did not have them.

The bigger ones I have pulled off the TV boards and cut the shrink off and unwrapped the copper, and the ferrite goes in your small metal bucket.

Magnetic as in permanent magnet, it sticks to the fridge or that a magnet sticks to it, because if the first it's probably a bi metal circuit breaker (thats my opinion, haven't actually put hands on one in a power supply yet)

I think you'll find that after electric flows thru it long enough then it probably magnetizes.

Ferrite is what speaker magnets are made out of. You can take a piece of ferrite and wrap a certain length of copper wire around it and hook to a battery and you've got an electrical magnet.

Tried to get as close to them as I could without the image getting all fuzy(camera only zooms in 1x digital zoom).

I would say yes as they have the egg shape and a + marking. Most normal everyday cap's have a - marking. Tantalum Epoxy cap's.

Do you per chance know how to read glass diodes? I have a bunch with a blue stripe on em, no numbers and most google searches were too confusing for my taste.

If your referring to the stripe being close to one end then it denotes the negative end of the diode. I don't think they put values on little glass diodes.
