Product Overview
0.022uF 100V Polyester Film Capacitor - Green Dipped Radial 2A223J, 5% Tolerance, Guitar Tone and Pedal Builds
Condition
Unused NOS - New Old Stock, sourced from legacy electronics supply chains. Evaluation: visual inspection only. Function testing was not performed. In the photos the green dipped epoxy body carries the code 2A223J printed in white across the face and still fully legible, and a small irregular light grey blemish sits at the lower left corner beside the lower lead exit, where the dip coating is thin or voided. Both radial leads are bright and untinned, with no solder and no tarnish; in the second photo the upper lead carries a visible kink partway along its length. The leads run off the frame in the first photo, so overall lead length is not confirmed. No ruler appears in either photo, so body dimensions are not confirmed. Backed by our no-hassle guarantee.

Product Overview
Radial-leaded polyester (Mylar) film capacitor rated 0.022uF at 100V DC with 5% tolerance, in the familiar green dipped epoxy body with a white printed marking. The code 2A223J decodes directly: 2A = 100V, 223 = 22000pF, J = 5%. Lead spacing is 5mm and the leads are not pre-formed to a board pitch, so you set your own bend for a turret board, a guitar control cavity, or a stripboard pedal layout. Also searched as 22nF, 22000pF, and 223 - the same value under three naming habits, and the standard tone cap value for guitar tone circuits, audio filter stages, and low-power timing work.

Applications
- Guitar tech rewiring a humbucker control cavity and matching the original 0.022uF tone cap value
- Pedal builder populating a stripboard fuzz or overdrive and needing a 22nF coupling or filter position
- Amp technician replacing a low-voltage tone stack or cathode bypass capacitor in a small combo
- Restorer of vintage consumer audio who wants a period-correct film cap instead of a modern box type
- Bench hobbyist stocking a few 22nF values for timing and decoupling experiments
Frequently Asked Questions
Is this safe to use in a tube amplifier?
Only in low-voltage positions. This capacitor is rated 100V DC. Do not put it in a plate circuit or anywhere 400V or more is present. Tone stacks, cathode bypass, and similar low-voltage spots are appropriate.
Is 0.022uF the right value for a standard humbucker tone control?
Yes. 0.022uF, printed as 223, is the standard tone cap value for humbucker-equipped guitars. Builders also use it in single-coil circuits when they want a darker roll-off than the usual 0.047uF choice.
Will it fit a tight guitar cavity or a compact pedal enclosure?
Lead spacing is 5mm. Body dimensions are not confirmed, and no ruler is present in the photos, so measure your clearance against your own layout before ordering if space is tight. The leads are not pre-formed, which leaves you room to bend them how you need them.
Can I use this for AC line filtering?
No. This is not an X or Y rated safety capacitor and it is not suitable for AC mains filtering. Use a properly rated safety capacitor for anything across or to the line.
These were never function tested. What am I actually getting, and what am I taking on?
You are getting an unused New Old Stock film capacitor exactly as photographed: green dipped body with a legible 2A223J marking and a small light grey coating blemish at one lower corner, plus bright untinned leads, the upper one with a slight kink. What was done is visual inspection. What was not done is measurement, so capacitance, tolerance, and leakage are unverified here and the printed code plus the photos are the whole spec. That is a fair trade at this end of the parts bin, and the fix is a thirty second check on a meter before it goes into a build you care about. Shipping is $8 flat rate, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Green epoxy, three digits, and a value that has been rolling the top off humbucker guitars since long before anyone called it a mod. Meter it, bend the leads to your layout, and let the tone knob finish the sentence.
