Product Overview
High-Voltage Ceramic Disc Capacitor - 1KV Rated, Through-Hole, Blue Disc Body
Condition
Unused NOS. Sourced from an electronics distributor consolidating inventory. Photos show the specific unit you will receive. The disc face is visibly marked "22K / 1KV" in black print on a blue ceramic body; this listing is offered as 152K-1KV per the seller's sourcing records. Buyers should confirm the visible markings meet their application requirements before ordering. No damage or discoloration observed.

Product Overview
High-voltage ceramic disc capacitor rated at 1KV (1000V), through-hole mount with radial leads. Blue ceramic disc body. Useful in power supplies, RF circuits, snubber networks, and filtering applications where voltage headroom matters.
Key Features
- Voltage rating: 1KV (1000V DC)
- Type: Ceramic disc, through-hole
- Disc body: Blue ceramic
- Lead type: Radial, straight wire leads
- Visible markings: 22K / 1KV on disc face
- Condition: Unused NOS - no wear, no damage observed
Applications
- Replacing a failed capacitor in the high-voltage section of a vintage TV or radio power supply - desolder the old disc, drop in the new one, verify it sits flush on the board
- Integrating into an SMPS or industrial power supply design where a 1KV-rated capacitor handles voltage suppression or high-frequency filtering
- Prototyping RF or snubber circuits on a breadboard or custom PCB where the 1KV headroom keeps the design from hitting voltage breakdown during testing
- Makers and hobbyists building or repairing high-voltage power supplies for tube amplifiers, Tesla coil drivers, or other high-voltage projects
Frequently Asked Questions
The listing says 152K-1KV but the photos show "22K / 1KV" on the disc. Which is correct?
The photos show the specific units you will receive, and the disc face is visibly marked 22K / 1KV. The listing part number 152K-1KV comes from the seller's sourcing records. Both sources confirm the 1KV voltage rating. Buyers should examine the photos closely and confirm the visible markings match what their application requires before ordering.
Is this a through-hole or surface-mount component?
Through-hole. The units have straight radial wire leads visible in the product photos.
Are these suitable for AC pulse circuits?
Ceramic disc capacitors of this type are generally not recommended for AC pulse circuits, as they can be susceptible to breakdown from impulse voltage. Best suited for DC and high-frequency filtering applications.
A solid 1KV-rated disc capacitor is the kind of part that sits in a drawer for years and then saves the day when a vintage power supply finally gives out. These are in clean, unused condition - ready to go back to work.
