Identifying 3 unkown components

[Sadlercomfort]

Hi guys, as a learning experience I'd like to identify these components. I have 3 types of components here which I can't identify on the internet.

The black components have no markings on them but the other two blue components are both Phillips. One seems to be measured in the unit μM and the other has lots of markings so it's not so clear. Anybody recognize them?

Thanks

Ash

First set looks like ferrite beads, 2nd looks like capacitors, but I'm not sure what's with the uM, and not sure on the 3rd set, get googling!

Second set are electrolytic capacitors 100uF 25V, but why uM? The negative end has a black belt !

The third set could be wire wound ceramic high temperature resistors or plastic capacitors.

If you have a multimeter, measure the resistance. If you see it going up and up and up (easier to see on an analogue meter) then you have a large value (100's of uF) capacitor.

If you have a capacitance range, that should indicate the capacitance.

Cheaper multimeters with inductance ranges typically have ranges which do not cover most inductors used in electronics.

The last photo cleverly hides the markings. They may provide a clue.

Ferrites, electrolytic capacitors and axial leaded fuses or precision resistors?

Okay so we're sure we have ferrites and most likely axial electrolytic capacitors. I need to check the accuracy of my multimeter on brand new capacitors before testing the capacitors as it's getting old.

I'm going to write out the markings on the last set of components because its much easier for you guys to see. If it helps, i found the last components on an old amplifier. Out of the 8 components, there are 4 different markings;

"270p
G400
KP B6
PHILIPS"

"100p
G630
KP B5
PHILIPS"

"1n5
F250
KP B5
PHILIPS"

"51p
F630
KP B5
PHILIPS"


Thanks for everyone who replied,

270pF,100pF,1500pf and 51pF capacitors.

Someone will be able to say what the second number is, I suspect voltage.
The third line may be dielectric or tolerance.

Just as Duke said, the last components are Film Polypropylene capacitors (plastic caps),
I found an example of one here http://www.tedss.com/2222-464-73011.

The axial plastic capacitors like this one is obviously less common than the radial leaded type.

Thanks everyone,
