Measures against problems in ceramic capacitors (MLCC)

  1. Quantity/Cost reduction
  2. Rudeness prevention / Anti-vibration
  3. Crack prevention measures
  4. Safety measure

Conductive products can solve the problem

1. Insufficient capacitance Quantity/Cost reduction

  • Capacitance of MLCC is reduced by Voltage application + Low temperature/High temperature
  • Capacitance of MLCC is reduced by Voltage application + Low temperature/High temperature
  • Quantity of MLCC and SP-cap/POSCAP

2. Squeaking / Micro vibration Rudeness prevention Anti-vibration

  • SP-Cap/POSCAP Rudeness prevention Anti-vibration
  • MLCC
    Expansion and contraction of
    element by Piezo effect
    (Generation of micro vibrations)

    SP-Cap / POSCAP
    No vibration
  • generation of squeals image

3. Cracks Crack prevention measure

  • MLCC is cracked by temperature/mechanical impact
  • MLCC is cracked by temperature/mechanical impact image

4. Fire spreading to board Safety measure

The red heat continues if MLCC is short-circuited.
