Unfortunately I could not identify this one.
KCK is a Mallory type of ceramic capacitor. I wasn’t able to locate a spec sheet on the KCK series. The 104 should be the capacitance value of 0.1uF. If you can figure out the voltage, then choose a cap from here
Hi al1,
Welcome to the TechForum.
I came across an old datasheet here which seems to indicate that KCK was a brand, perhaps acquired by Mallory, though I can’t find anything indicating so.
Within that document, it states that if there is no voltage printed on the part but there is an underline under the capacitance value, that the part is rated at 50V.
It also states that if the part is marked with an “F”, that it has a tolerance of ±1pF and that if colored orange, it has the “N150(P)” temperature coefficient (±1%) from -55°C ~ +85°C.
The part that does not make sense to me is the capacitance value. Your part appears to have “104” printed on it. That typically would mean 10 x104 pF, which is 100,000pF or 0.1uF. However, the tolerance and temperature coefficients listed above could not apply to a ceramic capacitor of that capacitance value, especially in that physical size. Such parts don’t exist.
If the marking were just “04” it would represent 4pF, which would make the other markings make sense. As is, I’m at a loss. If you could remove the part and measure it’s capacitance, assuming that it was still intact, that might help to determine the actual value. Also, if you have a schematic of your product, this might also help in identifying the right replacement part.
Are we sure it is a 1, it looks like it is connected making a strange L shape.
