Product Overview
152K-1KV is a blue ceramic disc capacitor rated 1500pF (1.5nF) at 1000V with ±10% tolerance. Through-hole, radial leads, non-polarized. Body diameter approximately 8mm with leads approximately 25mm long per photo observation. Built for high-voltage sections of power supplies, filtering stages, and snubber circuits where a compact, non-polarized, high-frequency-capable component is required.
Key Features
- Capacitance: 1500pF (1.5nF / 0.0015µF)
- Voltage rating: 1000V (1KV)
- Tolerance: ±10% (K designation)
- Dielectric: Class 2 ceramic (Y5P)
- Package: Through-hole disc, radial leads
- Non-polarized - no orientation requirement
- Blue disc body with black ink markings; straight silver leads on cardboard carrier
Applications
- Replacing a failed high-voltage cap in the filter or snubber stage of a power supply - desolder the old disc, drop this in, reflow, and verify output stability
- Swapping a failed bypass capacitor in the high-voltage section of older CRT monitor or TV equipment where a 1KV-rated disc is the correct replacement
- Maintaining motor drives or welding equipment with high-frequency control circuits that depend on a reliable 1500pF 1KV disc in the snubber network
- Prototyping a custom high-voltage power supply or LED driver where a through-hole 1KV ceramic disc fits the PCB footprint and keeps the BOM simple
- Stocking a repair bench with high-voltage ceramic discs for general-purpose substitution across multiple equipment types
Frequently Asked Questions
Is this capacitor polarized?
No. Ceramic disc capacitors are non-polarized. This one can be installed in either lead orientation without affecting performance.
What does the "K" in 152K mean?
"K" indicates ±10% capacitance tolerance. The "152" is the capacitance code: 15 followed by two zeros, giving 1500pF.
Is this suitable for precision timing or resonant circuits?
Not the best choice for those applications. As a Class 2 (Y5P) ceramic, capacitance shifts with temperature and applied voltage - a characteristic of this dielectric class. For stable timing or resonant circuits, a Class 1 (NP0/C0G) capacitor is a better fit. For filtering, bypassing, and snubber use, the Y5P performs well.
Does this fit standard through-hole PCBs?
Yes. Radial through-hole leads on a cardboard carrier. Photos show leads approximately 25mm long and a disc body approximately 8mm in diameter. Verify your PCB hole spacing before ordering if a tight footprint fit is critical.
A 1500pF ceramic disc that has been sitting quietly on a carrier strip, waiting for the circuit that needs exactly this. Find the right footprint, solder it in, and it gets back to the job it was made for.
