Product Overview
22K 1KV ceramic disc capacitor - 22,000 pF (22 nF / 0.022 µF) capacitance at a 1000V rating. The K designation indicates ±10% tolerance. Blue epoxy disc body with straight tinned axial leads, approximately 7mm body diameter and 12mm lead length as observed from photos. A non-polarized passive component used for filtering, bypass, and coupling in high-voltage circuits.
Key Features
- Capacitance: 22,000 pF (22 nF / 0.022 µF)
- Voltage rating: 1000V (1 kV)
- Tolerance: ±10% (K designation)
- Non-polarized - no orientation requirement for installation
- Blue epoxy disc body, approximately 7mm diameter
- Straight tinned axial leads, approximately 12mm long
- Markings confirmed: 22K and 1KV on disc face
Applications
- Repair tech swapping a failed high-voltage bypass cap in an industrial power supply or control board - desolders the faulty disc, drops this one in, confirms the circuit is stable again
- OEM assembler integrating a coupling or decoupling stage into a high-voltage power supply, voltage multiplier, or pulse circuit during prototype or small-run production
- Hobbyist building a custom high-voltage supply, Marx generator, or Tesla coil who needs a compact 1kV-rated ceramic that handles high-frequency demands without the bulk of stacked lower-voltage caps
- Field technician servicing X-ray equipment or TIG welding arc-start circuits where the original ceramic disc has cracked or shorted under thermal stress
- Maker adding EMI suppression or line filtering to a switching supply where a film cap would be too large and a lower-voltage ceramic would be unsafe
Frequently Asked Questions
Is this capacitor polarized?
No. Ceramic disc capacitors are non-polarized. Install in either orientation.
What is the lead spacing on this capacitor?
Lead spacing is not confirmed from the photos or sourcing documentation. The body is approximately 7mm in diameter as observed. Measure your PCB footprint before ordering if tight pitch tolerance is critical.
Is the dielectric type confirmed - X7R, Y5V, NP0?
Dielectric class is not confirmed for this specific unit. At 22nF and 1kV in a ceramic disc form factor, Class 2 behavior (capacitance variation with temperature and voltage) is typical for this combination. Buyers requiring a specific dielectric class should confirm suitability before use.
What is included with the order?
The capacitor only. No documentation or accessories included.
Can this replace a capacitor rated at a lower voltage, say 630V or 500V?
Yes - a higher voltage rating is a safe substitution provided the capacitance, dielectric behavior, and physical dimensions are compatible with your circuit and PCB layout.
A ceramic disc that has sat untouched in distributor stock is still exactly what it was the day it was made - no wear, no stress, no history. Yours now, ready to go back to work.
