Our take on the Dayton Audio PMPC-20 Precision Capacitor 20 uF 250 V

The Dayton Audio PMPC-20 is a 20 µF, 250 V metallized polypropylene film capacitor sold for speaker crossover work. Its tight tolerance and low-loss film dielectric make it a step up from standard electrolytic caps in clarity and long-term stability. It suits DIY speaker builders and repairers replacing a worn cap in a crossover. It is a single capacitor, not a kit, and its 27 mm diameter and 55 mm length need room on the board.

Pros
  • 20 µF at 250 V covers most tweeter and midrange crossover values
  • Polypropylene film gives low loss and stable capacitance over time
  • Tight tolerance keeps left and right speakers matched
  • Non-polarized, so orientation does not matter
  • Long service life compared with electrolytic caps
Cons
  • Physically large for a 20 µF part; check clearance before ordering
  • Costs more than a basic electrolytic of the same value
  • Two leads only, no mounting hardware included
  • Not suited to high-current power supply filtering

Questions and answers

Is 20 µF the right value for my crossover?
Match the value printed on the capacitor you are replacing. 20 µF is common in tweeter and midrange high-pass sections. Changing the value shifts the crossover point.
Does the 250 V rating matter in a speaker?
It gives ample headroom for the voltages a crossover sees. The rating is a maximum, not a target, so it is safe in normal speaker use.
Can I replace an electrolytic cap with this?
Yes, as long as the capacitance matches and it physically fits. Film caps like this are non-polarized, so either lead can go to either pad.
Will it fit my board?
It is about 27 mm across and 55 mm long, larger than an electrolytic of the same value. Measure the space and lead spacing before ordering.
Is it sold as a pair?
No, it is a single capacitor. Order two if you are recapping a stereo pair of speakers.
Where is the Dayton Audio PMPC-20 Precision Capacitor 20 uF 250 V cheapest?
At PARTS EXPRESS, for $14.99, as of our latest check.
