Import 30kv 0.5uf Capacitor 500nf 30000v Hv Capacitor — Buy in wholesale FOB from Supplier in China

The 30 kV 0.5 uF high-voltage capacitor from Pluspark Electronics Technolology Co., Ltd stores 500 nF at rated DC voltage up to 30,000 V, with a 10 per cent tolerance, 1 pps rep-rate and design lifetime of 100,000 charge-discharge cycles. Peak current capability is 25 kA and maximum RMS current is 25 A. The dielectric system uses metallised film in a low-inductance plastic case with copper terminals, a construction that reduces equivalent series inductance and improves pulse-shape fidelity in fast-discharge applications. This component is designed for particle accelerators, medical imaging, X-ray equipment and high-voltage power supplies where reliable energy storage and rapid energy release are critical.

Metallised film dielectric offers self-healing characteristics: localised dielectric breakdowns vaporise the thin metal layer around the fault site, restoring isolation without catastrophic failure. The plastic case construction contributes to lower weight and reduced stray inductance compared with oil-filled or ceramic-disk alternatives. Standard industry practice for this voltage class includes partial-discharge testing at elevated voltage, though buyers should confirm whether Pluspark performs 100 per cent screening or batch-level testing. Temperature coefficient, dissipation factor at operating frequency, and insulation resistance after humidity cycling are additional parameters that define real-world performance beyond the headline voltage and capacitance ratings.

Buyers in accelerator physics, radiography and pulsed-power research need capacitors with documented lifetime data under actual rep-rate and voltage-stress conditions. The 100,000-cycle figure is a design target; actual achieved lifetime depends on peak current, reverse voltage, cooling and operating temperature. Importers should request the supplier's accelerated-life test protocol, statistical distribution of failures, and whether individual capacitors carry date codes and batch numbers for traceability. Packaging for international B2B shipment typically uses foam-lined antistatic cartons; confirm with Pluspark whether dry-nitrogen purging or desiccant is included for moisture-sensitive storage.

Pluspark Electronics Technolology Co., Ltd maintains offices at #875 Qiuxing Road, Pudong, and No.188 Zhang Yang Road, Pudong New Area, Shanghai, China 201313. The company holds a harbor trust tier on the platform, with a zero percent response rate and no recorded average response hours, indicating that buyers may need to follow up proactively after initial enquiry. The source material does not state factory floor space, year of establishment, headcount, revenue, ISO certifications or named clients, so any such information must be requested directly and verified.

The listing emphasises immediate shipment availability and positions the capacitor for power electronics, particle accelerators, medical imaging and X-ray systems. No additional product families or custom-engineering capabilities are described in the source. Buyers should clarify whether Pluspark manufactures the film in-house or sources metallised film from a specified vendor, as this affects consistency and failure-mode predictability across production lots.
