Product Overview
CK05BX222K Radial Multilayer Ceramic Capacitor - 2200 pF, 100 VDC, BX Dielectric, 10 Percent Tolerance
Condition
New, unused stock, sold each. The photographed piece is marked in three lines on each face, CK05 / BX / 222K on one and 100V / K / 9220 on the other, printed in dark type on a flat-faced yellow molded epoxy case. The radial leads splay outward in a V from the body, silver-grey and clean, with no corrosion, kinks or solder on them. Small parts like this are stocked loose, so the piece you receive is a representative unit from the same holding and its date code may differ from the one photographed.

Product Overview
The CK05BX222K is a radial-lead multilayer ceramic capacitor, 2200 pF (2.2 nF, 0.0022 uF) at 100 VDC, with a BX dielectric and a 10 percent tolerance - the K in the part number is that tolerance code, and 222 is the 2200 pF value. CK05 is the case-size designation used by the MIL-C-11015 style family, and the leads sit on the 5.08 mm (0.200 inch) pitch this listing publishes, which drops straight into a 0.1 inch grid board on two-hole centers. BX is the military-style temperature-stable dielectric, the counterpart of commercial X7R, so it is the class you reach for when a bypass or timing cap has to hold its value across temperature rather than drift like a general-purpose Z5U. Neither printed face of the photographed piece shows a manufacturer logo or wordmark; what is printed is the style code, the voltage, the tolerance letter and the date code. The listing is catalogued as Unbranded.

Applications
- A repair technician rebuilding a 1990s control board who needs a few decoupling caps in the original CK05 footprint rather than a surface-mount substitute.
- An analog designer breadboarding a 555 or filter stage who wants a stable 2.2 nF that will not wander with temperature the way a general-purpose ceramic does.
- A ham radio operator restoring older transmit gear where 100 VDC headroom on a bypass cap is not optional.
- A lab or maintenance shop stocking a parts drawer with the odd MIL-style values that never seem to be in the assortment kit.
Frequently Asked Questions
What does CK05BX222K actually decode to?
CK05 is the case size and style, BX is the dielectric characteristic, 222 is 2200 pF (22 followed by two zeros), and K is the 10 percent tolerance. The photograph shows those same characters printed on the part in three lines - CK05 / BX / 222K - so you can match your bill of materials against the piece itself.
What is the temperature behavior of a BX dielectric?
BX is the military-style temperature-stable class, generally treated as the counterpart of commercial X7R and specified over the standard military range. The specific capacitance-change and voltage-coefficient limits for this piece are not confirmed here - verify against the MIL-C-11015 style sheet or a manufacturer datasheet before use in a precision timing or filter application.
Who made it, and is there a maker's mark on the part?
The listing is catalogued as Unbranded. On the photographed piece, neither printed face shows a manufacturer logo or wordmark - what is printed is the style code, 100V, the K tolerance letter and 9220, which reads as a date code. The two narrow edges of the case are not shown in these photographs, so we cannot speak to what may be on them. If you need traceability to a named manufacturer, this is not the piece for that job.
Will it fit a standard 0.1 inch perfboard?
The listing publishes 5.08 mm lead spacing, which is 0.200 inch, so the leads land two holes apart on a 0.1 inch grid. The leads in the photographs are formed, splaying outward in a V from the body rather than running down parallel, so expect to squeeze or spread them a little to line up with your hole centers.
Why buy three or four of these here instead of a bag of a hundred somewhere else?
Because a repair usually needs the count on the board, not the count on the reel. If your job takes two of these and a spare, you buy three and you are done - no forced lot of 50, no minimum order, no leftover bag of 97 in a drawer. The piece in the photographs is a representative sample of loose stock, not the specific piece set aside for your order. Shipping is $8 flat rate and it goes free once your order passes $28, so a few small parts still land cheap, and orders leave our Idaho warehouse the same or next business day.
Three lines of tiny dark print on a little yellow molded block, and one of them says 9220 - this thing was made while the board it was meant for was still in production. Somebody's board is still running, and it is quietly waiting for exactly this.
