Mystery Ceramic Cap?

Post by syscokid »

Friend of mine sent me this pic and asked me what values is the resistor and the cap in this treble bleed circuit? I can’t figure out the cap’s capacitance. I’m assuming this is a ceramic.

Maybe 680pF and 220KΩ 5%

That is a Vishay Y2 / X1 rated capacitor 680pf, 20%.

Y2 rated to 300v
X1 rated to 440

681 means 680pf

M means 20% tolerance.

Automotive grade.

The resistor is a garden-variety 220K carbon film.
