Product Overview
Rifa 022K630Y is a 22nF (0.022µF / 22,000pF) film capacitor rated at 630V, housed in a radial box package. Rifa, now absorbed into KEMET, produced this style of European box capacitor through the 1980s and 90s. The cream rectangular housing is characteristic of that era. Marking breakdown: .022 = 0.022µF capacitance, K = ±10% tolerance, 630 = 630V rating, Y = dielectric type or series designation (likely metallized polypropylene or polyester - not confirmed as a Y-class safety rating). Lead spacing not confirmed - verify against your PCB footprint before ordering.

Applications
- Replacement for failing Rifa capacitors in vintage power supplies and filter circuits
- Audio equipment recapping - common in amplifiers, receivers, and tuners from the 1980s-90s
- High-voltage filter and decoupling positions in older televisions, monitors, and radios
- SMPS and switching power supply filter stages requiring 630V film capacitors
- Makers and hobbyists building high-voltage projects such as Tesla coil drivers, vacuum tube circuits, or spark gap transmitters where a 630V rated film cap fits the bill
- Vintage computer restoration - power supply boards that used this class of European film capacitor
Frequently Asked Questions
Is this a Y-class safety-rated capacitor for across-the-line AC mains use?
Not confirmed. The Y in the part marking most likely indicates a dielectric type or series designation, not a Y-class safety rating. Do not use this capacitor in an X or Y safety-rated position in mains EMI suppression circuits unless you can verify its safety classification against a datasheet for this specific part number.
What is the lead spacing on this capacitor?
Not confirmed. Common lead spacings for Rifa radial box film capacitors in this value range include 10mm, 15mm, and 22.5mm. Measure your PCB footprint and verify before ordering.
Is a datasheet available?
No datasheet for this exact part number is included. Based on the markings and physical style, it is likely a PHE426 series or similar Rifa film capacitor, but that is not confirmed. Verify specs against your circuit requirements before use.
Are the leads usable as-is for PCB installation?
Yes. Both leads are straight, unsoldered, and untrimmed per the photos. Ready to solder directly into a through-hole PCB position.
There is something satisfying about pulling a 1980s European capacitor out of old stock and putting it exactly where it belongs - back inside a piece of vintage gear that has been waiting for it. Straight leads, correct value, ready to solder. The recap starts here.
