Product Overview
Radial-lead ceramic disc capacitor rated 2200 pF (2.2 nF) at 1000V, marked 22K-1KV. K tolerance code indicates ±10%. Blue epoxy body, approximately 10mm diameter, with kinked radial leads for through-hole PCB mounting. CC81-style commodity component. Non-polarized – installs in either orientation.
Key Features
- Capacitance: 2200 pF (2.2 nF / 0.0022 µF)
- Voltage rating: 1000V (1 kV)
- Tolerance: ±10% (K code)
- Package: Radial-lead ceramic disc, through-hole
- Body: Blue epoxy, approximately 10mm diameter
- Non-polarized – no preferred orientation
- Markings: 22K and 1KV confirmed on disc face
Applications
- Replacing a failed bypass or coupling capacitor in the high-voltage section of a CRT monitor, vintage television, or flyback-driven power supply – desolder the old disc, confirm 2200pF 1kV, drop this in
- High-voltage bypassing and decoupling on a PCB where the design calls for a ceramic disc at or near line voltage
- Snubber networks and switching power supply designs where ceramic disc construction handles the fast transients
- Breadboard and lab experiments exploring high-voltage filtering, coupling, or energy storage without reaching for costlier precision types
- Student and maker projects involving HV circuits – robust enough for hands-on use, commodity pricing means mistakes are not expensive
Frequently Asked Questions
Is this capacitor polarized?
No. Ceramic disc capacitors are non-polarized and can be installed in either direction.
What lead spacing should I expect?
The research data for this CC81-style component lists typical radial lead spacing of 5mm or 7.5mm. Exact spacing for this specific lot is not confirmed from markings or photos – measure before committing to a PCB footprint.
Is this a Class 1 (C0G/NP0) or Class 2 ceramic?
The dielectric class is not marked on the component. The K tolerance (±10%) and CC81-style construction are consistent with Class 2 ceramic (Y5P or similar). Class 1 C0G/NP0 parts of this value carry tighter tolerances. If your application requires stable capacitance across temperature and voltage, confirm the dielectric type matches your design requirements before ordering.
What does this capacitor weigh – can I order multiples?
These are small commodity components. Volume pricing is available – see the listing price tiers. Ships same business day from Idaho.
The markings are right there on the disc – 22K, 1KV, nothing hidden, nothing to decode. Pull the old one out, read the body, confirm it matches, solder this one in.
