Technical Specifications

Application Scenarios

High voltage ceramic capacitors are primarily used in high voltage electric equipment. Specific application areas include:

• 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
• Power plant control equipment
• Transportation equipment (vehicles, trains, ships, etc.)
• Traffic signal equipment
• Disaster prevention / crime prevention equipment
• Data-processing equipment
• Applications of similar complexity and/or reliability requirements.

Cautionary Notes

Users are advised to adhere to the following precautions:

• Operating Voltage: Maintain applied voltage within rated limits, considering AC, ripple, and transient voltages.
• Operating Temperature and Self-Generated Heat: Keep surface temperature below rated limits, accounting for self-generated heat due to dielectric loss, especially in high-frequency or pulse current applications.
• Operating and Storage Environment: Avoid corrosive atmospheres, moisture, and ensure adequate insulating media (3mm or more) when used in insulating media. Store between -10 to 40 C and 15 to 85 % relative humidity. Use within 6 months of delivery.
• Vibration and Impact: Avoid excessive shock or vibration.
• Soldering: Adhere to specified soldering conditions (tip temperature, wattage, time) to prevent damage.
• Limitation of Applications: Contact HVC before using in applications requiring exceptionally high reliability to prevent damage to third-party life, body, or property, such as aircraft, aerospace, and medical equipment.
• Cleaning: Observe ultrasonic cleaning conditions (bath capacity, rinsing time) to prevent lead wire fatigue.

Capacitance Change Characteristics

• Class 1 capacitors: Capacitance may slightly change with surrounding temperature or applied voltage. Contact HVC for strict time constant circuits.
• Class 2 and 3 capacitors: Exhibit aging characteristics (capacitance decrease over time) and significant capacitance changes with temperature and voltage. Not suitable for time constant circuits. Contact HVC for detailed information.
