Selection Guidelines
High-voltage ceramic capacitors require careful selection and handling. Consider these critical factors:
Voltage Margin: Operating voltage must be significantly below rated voltage, accounting for peak pulse conditions
Thermal Management: Proper heat dissipation is essential for high-frequency/high-current applications
Frequency Characteristics: Performance varies by dielectric material - consult detailed specifications
Safety Compliance: All design, installation and operation must follow strict safety regulations by qualified personnel
