    I'm trying to identify a component which has no numbers or identifying marks. It's canary yellow and has 2 leads coming out of the bottom. The circuit board has the number "104" in the components location. there are 6 of these components on the board. They act like diodes as I use an analog ohm meter, they will pass voltage in one direction only. I've attached a pic with two of the components highlighted.

    Thanks in advance for any help!

    Pass voltage only in one direction while still in circuit?

    Remove one and I'll bet it doesn't pass anything, probably just 0.01 uF caps by the looks of them.

    102 = 1000pF = 0.001uF = 1N

    103 = 0.01uF = 10N

    104 = 0.1uF = 100N

    Yes - they are in circuit still. Was just curious what they are. They don't appear to be bad so I didn't want to un-solder them to take them out and risk damage. Thanks for the replies! They probably are caps.

    Measuring components values in circuit, using a DMM. Is often not the best approach. As you will also measure on every other component connected in parallel. If you do not have a schematic you can check with. The measurements will more or less be random
