Please help identify funny CAPACITOR type identifier.
Hi, I am recently reading a schematics for a parametric filter for
audio application, and in service manual they have listed the type and value of all the capacitors they uses. They have POLY ( for polyester ), ELEC ( for electrolytic ), and a mystery one called PLAQ. I wonder if anyone can help me identify what type of capacitor that stands for. These PLAQ capacitors are all in the range of a few hundred pF to a couple of nF. Most of them are placed across the 'OUT' and the '-' termainal of opamps ( together with other feedback components) . Looking at the circuit board, they are greyish/light brownlish in color and look very much like ceremic capacitors in size and shape (they are all dipped with a color band on top). Thanks. you know what to remove to reply to ! |

I cannot remember exactly the acronym meaning for PLAQ, but these are
plate capacitors, if I remember right. Visit the link below. http://www.angliac.com/bce/index.asp You can infact use ceramic disk capacitors, and they should work for you. -- Jerry G. ====== "Al" wrote in message om...

Thanks Jerry. I think you are right. The ceremic plate caps on the
website looks exactly like those on the parametric eq unit I had, down to the color band on top, which encodes the dielectric material, like NP0 and X5S. |
