Stepper drive repair Capacitor ID

[CalG]

Hi

I'm trying to revitalize a Parker Compumotor S6 stepper drive.

One of the parts in particular has had all the smoke let out of it ;-)

the component board ID is "C3" and it's a small ceramic capacitor. Yellow gold (mustard) in color.

The ID on the side still readable is marked "106 6K" and the + leg is identified.

An uncertin search of several mfgs web pages suggest that this might be several things.

The "K" may indicate a 10% precision. But The meaning of the "6" is unclear.
The 106 may indicate capacitance (10 with 6 zeros?)

Other similar shaped caps on the boards have the microfarad values and voltage as thier markings. This destroyed piece is marked a bit differently.

Some caps of the same "color, but not rdial configuration are marked RSC 104, MHM 124 perhaps this gives a clue to the manufacturer.

You might know I am not well versed in electronic components.

Will anyone steer me to identification of a useful replacement?

TIA

It sounds like this is a tantalum capacitor as ceramic's do not have +markings as they are not polarized and 106 is 10uf which is too big for a ceramic.
The 6K may be a 6volt capacitor, Tantalum caps are often used as filter bypass on the power supply lines. These fail because of too high a voltage or a reversed voltage applied to them. It is not likely the cause of the problem but the result of some other failure.
Is the board completely dead or is it just not working as it should?

Thanks for the reply.

Yes, 6 volts and 10 micro farads sounds just right for a cap on the logic side of this supply. The problem is that one of the outputs is not delivering, so step motors just buzz and don't go round and round.
There is likely just the part to replace the damaged piece in my junk box.

Thanks
