Product Overview
The Orange Drop That Amp Techs Trust: Sprague 225P Film and Foil, 0.56uF at 100VDC
Condition
Unused, new old stock, photographed from the actual lot. Each body is printed SPRAGUE 225P (some pieces read 225PY) .56 plus or minus 10 percent, 100 DC, with the solid bar marking the outer foil end printed beside the text. The orange epoxy coating is glossy and intact, no chips or cracks. Leads are factory length; a few carry light shelf dulling and gentle bends from bulk storage, nothing a trim will not clean up. Against the caliper the body measures approximately 30 mm end to end. 18 in stock.

Product Overview
The Sprague Type 225P is a polyester film and aluminum foil capacitor dipped in the orange epoxy coating that gave the Orange Drop line its name. These are marked 0.56uF at a plus or minus 10 percent tolerance and rated 100VDC, with radial leads, crisp factory printing, and the printed outer foil band that lets audio builders orient the capacitor with the outer foil toward the low impedance side. Film and foil construction is non-polarized and known for mechanical durability and stable behavior in signal paths, which is why Orange Drops turn up in guitar amplifier tone circuits, audio coupling stages, and industrial control boards decade after decade.

Frequently Asked Questions
Will this work in a guitar amp tone circuit?
Yes. 0.56uF film capacitors are common in coupling and tone-shaping positions. Confirm the 100VDC rating meets the voltage at that point in your circuit before installing.
Is this polarized?
No. Film and foil capacitors are non-polarized and can be installed in either orientation. The printed band simply marks the outer foil end for builders who like to orient it toward the grounded or low impedance side to reduce noise pickup.
Why do some pieces read 225P and others 225PY?
Both prints appear in this lot, as the group photo shows. The value, tolerance, and voltage markings are identical: .56, plus or minus 10 percent, 100 DC. If the exact suffix matters for your documentation, ask before ordering and we will pull accordingly.
Can it substitute for another 0.56uF film capacitor?
If your circuit calls for 0.56uF at 100VDC or less and the roughly 30 mm body with radial leads fits your layout, this is typically a suitable replacement. Verify voltage and physical fit against your board.
How many are available?
18 pieces, new old stock. When they are gone, restocking this exact value is not guaranteed.
Why buy two or three here instead of a bag of 50 online?
An amp recap rarely needs more than a few of any one value. PartsMine sells exact quantities, so you can order the two or three you actually need. Shipping is $8 flat rate, free over $28, which usually lands well under the cost of a forced bulk lot. Same or next business day shipping from Idaho.
Orange Drops earned their spot inside amp chassis the slow way, one reliable decade at a time. This one has been waiting in its epoxy jacket since it left the Sprague line, and your signal path gets to be the reason it finally goes to work.
