High Voltage MLCC Usage in Compact Power and Filtering Circuits

High voltage multilayer ceramic capacitors are increasingly used in compact power conversion
and signal filtering applications where board space is limited and high dielectric strength is required.
X7R dielectric systems provide stable capacitance across temperature and voltage conditions,
supporting reliable operation in medium-voltage DC circuits.

High Voltage MLCC Characteristics

High voltage MLCCs combine multilayer structure with ceramic dielectric materials
to achieve high capacitance values in small surface mount packages.
Typical applications include snubber networks, DC filtering, and voltage smoothing
in switching power supplies and control circuits.

  • X7R dielectric for temperature stability
  • Surface mount structure for high-density PCB layouts
  • Suitable for medium-voltage DC applications
  • RoHS compliant construction

Package and Assembly Considerations

1206 and 1210 chip sizes are commonly used in high voltage MLCC designs,
providing a balance between capacitance value and voltage handling capability.
Tape and reel packaging supports automated placement in SMT production.

  • 1206 and 1210 chip sizes
  • Tape and reel packaging for SMT assembly
  • High insulation resistance for DC circuits

Applications

  • Snubber and damping networks
  • DC-DC converter filtering
  • Power supply voltage smoothing
  • Industrial control circuits
  • Medium-voltage signal conditioning

Design Considerations

  • Verify DC voltage rating with appropriate derating margin
  • Consider dielectric capacitance variation under DC bias
  • Select package size based on voltage stress and capacitance requirement
  • Ensure proper PCB creepage and clearance for high voltage nodes
