Important Cautions

• Operating Voltage: Maintain Vp-p or Vo-p within rated voltage range for AC/ripple circuits. Account for transient voltages during power application/removal.
• Operating Temperature and Self-Generated Heat: Keep surface temperature below the upper limit. Consider self-generated heat due to dielectric loss, especially with high-frequency or pulse currents. Applied voltage should limit self-generated heat to within 5C at 25C ambient.
• Operating and Storage Environment: Avoid corrosive atmospheres (chloride gas, sulfide gas, acid, alkali, salt) and moisture. Ensure at least 3mm of insulating media for cleaning, bonding, or molding. Store between -10C to 40C and 15% to 85% relative humidity. Use within 6 months of delivery.
• Vibration and Impact: Avoid excessive shock or vibration.
• Soldering: Adhere to solder heat resistance specifications (400C max. tip temp., 50W max. wattage, 3.5s max. time). Failure to comply may result in short circuits or product damage.
• Limitation of Applications: Contact HVC before using in applications requiring extremely high reliability for the prevention of defects that could cause damage to third-party life, body, or property. These include aircraft, aerospace, undersea, power plant control, medical, transportation, traffic signal, disaster prevention/crime prevention, and data-processing equipment.
• Cleaning: For ultrasonic cleaning, observe conditions: 20W/liter max. rinse bath capacity, 5 min max. rinsing time. Do not vibrate PCB/PWB directly.
• Capacitance Change: Class 1 capacitors may have slight capacitance changes with temperature/voltage. Class 2 and 3 capacitors (e.g., B, E, F temperature characteristics) exhibit aging and significant changes with temperature/voltage, making them unsuitable for strict time constant circuits.
