High Voltage Coupling Capacitor

These High-Voltage Coupling Capacitors use N4700 material, and they're built for ultra-high-voltage circuits-like, we're talking 50kV and above. They do signal coupling and voltage division when things get extreme. Pretty critical stuff.

You'll find these in power system monitoring setups-they're kind of a core piece there. Also show up in ultra-high-voltage pulse generators and high-end aerospace power supply modules. They work reliably from -40°C to +80°C and meet the IEC 60384-14 ultra-high-voltage standard. Even in environments with nasty electromagnetic interference, they still do their job-signal coupling and voltage division-with decent precision. Keeps your ultra-high-voltage gear running safe.

The core's made with lead-free N4700 ceramic. High dielectric strength, handles voltage really well. Manufacturing follows RoHS, REACH, and even aerospace-grade standards-so yeah, they don't mess around. Raw materials go through multiple purification steps upfront to make sure insulation and voltage endurance are solid from the start. They use this special gradient dielectric lamination process plus high-temperature noble metal electrode sintering-fancy stuff that helps resist corona discharge and dielectric breakdown. Then everything gets sealed up in this custom red epoxy resin with high insulation properties, and they put it through ultra-high-voltage curing and thermal cycling tests to make sure it's tough. Every single capacitor gets tested at over 100kV-just to be sure it won't fail when things get real.

Temperature stability's solid-capacitance only varies within ±22% across the whole operating range. You got options from 500pF to 1000pF, tolerance within 10%, so it covers most ultra-high-voltage circuit needs. Insulation resistance? Over 200,000 MΩ. Leakage current is basically zero. Dielectric loss is super low (≤0.1%), so even under ultra-high voltage, you're not wasting energy as heat. Rated at 50 kV, but dielectric strength goes over 100 kV-that's a 100% safety margin, way above industry standards. So dielectric breakdown? Not happening. Need different capacitance or size? They can customize it. The red casing makes it easy to spot and adds protection. Lead-free too, so it's good for pretty much any market.

Made with quality eco-friendly materials. Lead-free. Meets all the usual international standards.
