Application Scenarios
These capacitors are primarily used in high voltage electric equipment. Specific application areas mentioned include high-end medical electronic equipment (CT, medical X-ray machines, C-arms, DR machines, dental X-ray machines), airport security, non-destructive testing, and electrostatic dust removal equipment. They are also suitable for applications requiring similar complexity and reliability.
Limitations of Applications
Contact HVC Capacitor before using products for applications requiring especially high reliability, including aircraft equipment, aerospace equipment, undersea equipment, power plant control equipment, medical equipment, transportation equipment (vehicles, trains, ships, etc.), traffic signal equipment, disaster prevention/crime prevention equipment, data-processing equipment, and applications of similar complexity and/or reliability requirements.
Cautionary Notes
- Operating Voltage: Maintain Vp-p or Vo-p within rated voltage range for AC or ripple current circuits.
- Operating Temperature and Self-Generated Heat: Keep surface temperature below rated limits, accounting for self-generated heat (within 5C rise at 25C ambient for high-frequency/pulse current).
- Operating and Storage Environment: Avoid corrosive atmospheres and moisture. Ensure 3mm or more insulating media. Store between -10 to 40C and 15 to 85% RH. Use within 6 months of delivery.
- Vibration and Impact: Avoid excessive shock or vibration.
- Soldering: Adhere to specified temperature, wattage, and time limits to prevent damage.
- Cleaning: Observe ultrasonic cleaning conditions (20W/L or less, 5 min max.) to prevent lead wire fatigue.
Capacitance Change Characteristics
- Class 1 Capacitors: Slight capacitance change with temperature or applied voltage. Contact for strict time constant circuits.
- Class 2 and 3 Capacitors: Exhibit aging (capacitance decrease over time) and significant changes with temperature/voltage. Not suitable for time constant circuits. Contact for detailed information.
