Import Spraying Gun Capacitor With Diodes — Buy in wholesale FOB from Supplier in China

The Spraying Gun Capacitor With Diodes is a high‑voltage stack capacitor that incorporates silicon diodes to form a voltage‑doubler module for electrostatic spray equipment. It is supplied by Dongguan Amazing Electronic Co., Ltd. in China and features a blue glazed ceramic/polymer composite coating that can withstand rated voltages from 10 kV up to 50 kV. The listed electrical parameters include a capacitance range of 10 pF to 103 pF, tolerance of ±10 %, insulation resistance of at least 10 000 MΩ, and loss tangent not exceeding 0.3 %. The device operates at a typical frequency of 1 kHz and passes a DC 1.5‑times withstand test without flashover.

The capacitor’s construction combines a ceramic or polymer dielectric with copper leads and integrated diodes, giving a compact size - for example the CDM20KV151KB12 model measures 6.1 mm in diameter and 71 mm in length and contains twelve units per stack. Series A models use silver‑fitted connections for improved heat distribution and reliability, while Series B models employ direct welded leads for a more economical solution. In the wider industry, similar high‑voltage stack capacitors are typically sized between 5 and 9 mm in diameter and 60 to 90 mm in length, and they are built to IEC 60068 environmental test standards. The blue glazed coating provides resistance to dust, oil and humidity, which is essential for harsh spray‑gun environments.

These capacitors are used in electrostatic painting systems, powder‑coating rigs, agricultural sprayers, photomultipliers and ionisation chambers that require stable high‑voltage rectification. Buyers such as equipment manufacturers and system integrators normally request bulk packaging, FOB or CIF terms, and they should confirm lead‑time and minimum order quantity directly with the supplier as these details are not disclosed in the listing. The supplier indicates that custom module configurations and multi‑level stacks are available, so importers can discuss specific voltage or capacitance requirements during negotiation. All trade terms, including payment method and inspection rights, should be agreed before shipment.

Dongguan Amazing Electronic Co., Ltd. is located at Shijing Area, 65# Guanzhang Rd, Dongguan, Guangdong, China. The company is listed with a harbor trust tier on the platform, but its response rate is recorded as 0 % and no average response time is provided, indicating that communication may require proactive follow‑up. The profile states that the firm supplies high‑voltage capacitors with integrated diodes for industrial spray‑gun applications, but it does not disclose production capacity, certifications, or pricing information.

The listing highlights that the product can be customized in terms of voltage level, capacitance value and stack configuration, and that the blue glazed coating is intended for operation in dusty or oily environments. No specific MOQ, lead‑time or quality‑assurance certificates such as IEC or RoHS are mentioned, so buyers should request the relevant test reports directly from the supplier. The supplier’s address and trust tier are the only verifiable details available from the public profile.
