Product Overview
Shin Shin 223K630 Metallized Film Capacitor, 0.022 uF at 630 V, Radial Leads
Condition
New. The photographed piece is representative of our stock. The red epoxy-dipped box body is clean and sharp-cornered, printed 223K630 above the oval SHIN SHIN wordmark, with a faint light streak in the coating near the top edge that is a molding and dipping artifact rather than handling wear. Both radial leads are full length, straight, uncut and carry no solder or flux residue. Marking parity is stated for the piece in these photos only.

Product Overview
This is a Shin Shin metallized film capacitor in the familiar red box-epoxy radial package, marked 223K630 on the face. Read in standard capacitor code, 223 is 22,000 pF, which is 0.022 uF or 22 nF; K is the plus or minus 10 percent tolerance class; and 630 is the voltage rating printed on the part. The original listing also carries the Dalbani cross-reference item number 630V223K-7X9X4, which is useful if you are matching a line item on an old distributor invoice. The printed face does not show a dielectric family, a working-voltage type, or a date code, so the marking above is all the part tells about itself on the side we can see. Metallized film construction in this style is the usual choice where a technician wants a non-polarized part with modest self-healing behavior and a voltage headroom that ceramic bench stock rarely reaches.
Key Features
- Marking: 223K630, printed on the body face
- Capacitance: 0.022 uF, also written 22 nF or 22000 pF

- Voltage: 630 V as marked
- Construction: metallized film, red epoxy-dipped box body
- Lead style: radial, both leads from one edge, full length and uncut on the photographed piece
- Brand: Shin Shin, oval wordmark on the body
- Cross reference: Dalbani item number 630V223K-7X9X4
- Condition: New
- Dielectric family and AC versus DC working voltage: not confirmed - verify against the manufacturer datasheet before use
Applications
- Guitar amp technician replacing a coupling capacitor between tube stages, where a 630 V part gives comfortable headroom over the plate supply
- Vintage radio and test gear restorer recapping a chassis and wanting a non-polarized film part rather than a ceramic substitute
- Power supply builder needing a small film capacitor across a switching node, after confirming the working-voltage type suits the waveform
- Bench prototyper putting together a high-voltage timing or filter network on perfboard, buying three pieces instead of a bag of fifty
Frequently Asked Questions
What does the 223K630 marking actually mean?
223 is the three-digit capacitance code: 22 followed by three zeros in picofarads, so 22,000 pF, which equals 0.022 uF or 22 nF. K is the tolerance letter for plus or minus 10 percent. 630 is the voltage rating stamped on the part. That is the full marking on the printed face - no date code or dielectric letter appears alongside it, and the reverse and sides are not pictured.
Is the 630 V rating DC or AC?
Not confirmed. The body prints 630 with no DC or AC qualifier, and we have not tested it. Treat it as a DC and pulse working voltage until you confirm otherwise, and check the manufacturer datasheet before putting it across an AC line or into a mains-facing snubber, where the AC rating is normally far lower than the DC number.
What film is inside - polyester or polypropylene?
Not confirmed. The listing establishes metallized film construction and the printed face carries no dielectric code, so if your design depends on the difference in dissipation factor or temperature behavior, verify against the datasheet before you commit the part.
Will I get the exact capacitor in these photos?
No, and you should not expect to. These photos show one representative piece from our stock of this part. We describe the markings and the lead condition for the photographed piece only, and we make no promise that another piece will match it in those details.
Why buy two or three from PartsMine instead of a bag of one hundred somewhere else?
Because a recap job or a prototype usually needs a small handful, not a hundred, and the leftover ninety-seven live in a drawer forever. Here you count out exactly what the chassis takes. Shipping is $8 flat rate and free once your order passes $28, so it is worth filling the cart with the other odds and ends the same repair needs, and orders leave our Idaho warehouse the same or next business day.
Twenty-two nanofarads is an unremarkable number until you put 630 volts behind it, and that is exactly the corner where a red box cap stops being generic and starts being the only thing in the drawer that will hold. Count out what your chassis takes and get the rail back where it belongs.
