High Voltage Chip Ceramic Capacitors for Compact Power and Filtering Circuits

High voltage chip ceramic capacitors are used in circuits requiring elevated DC voltage ratings while maintaining compact surface mount dimensions.
They support filtering, coupling, and energy buffering functions in power conversion and communication equipment.
The TS18H series provides multiple chip sizes to accommodate different voltage and layout requirements.

Voltage and Package Options

High voltage MLCC structures enable operation from hundreds of volts to several kilovolts depending on capacitance and dielectric design.
The TS18H series is available in standard chip dimensions for high-density PCB assemblies.

• High voltage ratings from 500 V to 5 kV
• Chip sizes: 0603, 0805, 1206, 1210, 1808, 1812, 2225
• Surface mount configuration for automated assembly
• Suitable for compact high-voltage layouts

Electrical Function in Power Circuits

In DC-DC converters, high voltage ceramic capacitors are used for input and output filtering as well as snubber networks.
They provide low impedance at high frequency and support suppression of switching noise.
Stable dielectric performance is required to maintain capacitance under applied DC bias.

• Filtering in DC-DC converter stages
• Snubber and damping networks
• High-frequency noise suppression
• Coupling and decoupling in high-voltage nodes

Applications

• DC-DC converters
• Telecommunication circuits
• Electrographic equipment
• Modems and signal processing systems
• High-voltage filtering networks

Design Considerations

• Verify voltage derating for long-term reliability
• Consider capacitance variation under DC bias
• Ensure adequate creepage distance on PCB layout
• Select package size based on voltage and capacitance requirements
