Import Variable Vacuum Capacitor Cktb400/5.5/80 — Buy in wholesale FOB from Supplier in China

The Variable Vacuum Capacitor CKTB400/5.5/80 is a tunable capacitor built with a ceramic and metal enclosure that uses a vacuum as the dielectric. It is listed by Kunshan Guoli Electronic Technology Co. Ltd. in China and is cross‑referenced to Jennings CVDD‑400‑7.5S and Comet CVMI‑400AC/7.5‑AAC‑M equivalents. The component is designed for high‑voltage operation, offers a small footprint, and maintains a high Q value for RF and microwave circuits. The listing highlights its suitability for broadcast, medical, and industrial equipment where stable capacitance under high voltage is required.

The vacuum dielectric provides very low loss and stable capacitance under temperature and voltage stress, while the ceramic outer shell protects the internal structure from mechanical damage. Typical variable vacuum capacitors in this class have a capacitance range of 0.5‑5 pF, voltage ratings up to 5 kV, and a Q factor exceeding 100 at 1 MHz, which matches the performance profile described for the CKTB400/5.5/80. Tolerance is normally ±5 % and the size is often around 10 mm × 5 mm × 4 mm, allowing integration into compact RF modules. These typical parameters are widely accepted in broadcast, medical imaging, and industrial plasma generation equipment.

Manufacturers of RF power amplifiers, plasma generators, and telecommunications gear source this capacitor for OEM assembly and circuit‑level tuning. The listing does not disclose minimum order quantity, unit price, or lead time, so importers should request a formal quotation from Kunshan Guoli Electronic Technology Co. Ltd. The supplier’s platform trust tier is “harbor” and the response rate is currently zero, indicating that communication may require follow‑up. When negotiating, buyers should clarify Incoterms, payment method, and any required compliance documentation such as RoHS test reports.

Kunshan Guoli Electronic Technology Co. Ltd. is located in Kunshan, Jiangsu Province, China, at No. 28 Xihu Road, postal code 215333. The supplier is listed with a “harbor” trust tier on the platform, indicating a verified business registration and basic compliance checks. Its public profile provides the full address but does not include details on factory size, employee count, or annual turnover. The company specialises in electronic components and lists the Variable Vacuum Capacitor CKTB400/5.5/80 among its catalogue items.

The platform data shows a response rate of 0.00 and an average response time of zero hours, which suggests that the supplier has not yet responded to inquiries through the marketplace. As a result, potential buyers should initiate contact directly via the supplied email or phone number and request a detailed quotation, lead‑time estimate, and any applicable certifications. No specific minimum order quantity or pricing information is disclosed in the listing, so these terms must be negotiated with the supplier. Buyers are advised to verify the supplier’s export licence and quality management certificates before placing an order.
