Technical Specifications

Application Scenarios

High voltage electric equipment, high-end medical electronic equipment (CT, medical X-ray machines, C-arms, DR machines, dental X-ray machines), airport security, non-destructive testing, electrostatic dust removal equipment. Also used in aircraft equipment, aerospace equipment, undersea equipment, power plant control equipment, transportation equipment (vehicles, trains, ships, etc.), traffic signal equipment, disaster prevention/crime prevention equipment, data-processing equipment, and applications with similar complexity and/or reliability requirements.

Cautionary Notes

Operating Voltage: Maintain Vp-p or Vo-p within rated voltage range for AC/ripple circuits. Account for irregular voltages during power transitions. Operating Temperature and Self-Generated Heat: Keep surface temperature below rated limits, consider self-generated heat from dielectric loss (aim for <5C rise at 25C ambient). Use appropriate thermocouple for measurement. Operating and Storage Environment: Avoid corrosive atmospheres (chloride gas, sulfide gas, acid, alkali, salt) and moisture. Ensure 3mm insulating media for each direction. Verify cleaning, bonding, or molding processes do not affect performance. Storage: -10 to 40C, 15 to 85% RH. Use within 6 months of delivery. Vibration and Impact: Avoid excessive shock or vibration. Soldering: Adhere to solder heat resistance specifications (Iron-tip: 400C max., Wattage: 50W max., Time: 3.5s max.) to prevent internal damage. Limitation of Applications: Contact manufacturer before using in applications requiring especially high reliability (aircraft, aerospace, medical, etc.). Cleaning: Observe ultrasonic cleaning conditions (20W/L, 5min) to prevent lead wire fatigue. Capacitance Change: Class 1 capacitors may show slight changes with temperature/voltage. Class 2/3 capacitors (e.g., B, E, F characteristics) have aging and significant changes with temperature/voltage, making them unsuitable for strict time constant circuits.

Company Profile

HVC Capacitor Manufacturing Co., Ltd. is a Hong Kong-funded enterprise established in January 2012, operating as an export brand of a Taiwanese manufacturer with over 20 years of experience in high-voltage ceramic products. The production base is located in Dongguan Humen, with 95% of products exported. HVC specializes in high-voltage ceramic capacitors, including blue ceramic disc and bolt types. Their ceramic disc capacitors range from 2KV to 50KV, featuring the unique patented N4700 military-grade ceramic dielectric material (6KV to 40KV). Bolt-type ceramic disc capacitors, primarily using N4700 material, cover voltages from 10KV to 150KV and are encapsulated in black epoxy resin. Key clients include global leaders like General Electric, Konica Minolta, Hitachi ABB, Nikon, Siemens, Johnson & Johnson, and Baker Hughes. HVC aims to produce high-quality electronic components meeting international industrial standards using Chinese military-grade materials. Since 2017, HVC has successfully filled market gaps left by other brands due to commercial considerations and the pandemic. In 2018, HVC expanded its product lines to include high-voltage diodes and thick-film resistors through acquisitions and collaborations. The company has international distributors in Germany, France, the UK, the USA, Japan, South Korea, India, and Russia, and also established Chinese distributors to serve foreign-funded factories in the Chinese market. HVC's goal is to become a recognized emerging brand in the high-voltage electronic components industry.

International Distribution

Distributors are located in Germany, France, the UK, the USA, Japan, South Korea, India, and Russia. China distributors are also available to cater to the needs of foreign-funded factories in China. Distributors are appointed by HVC to follow up with key local customers.
