Conductive Polymer Tantalum Solid Capacitors (POSCAP)

Zoom
POSCAP utilizes sintered Tantalum as an anode sytem and highly conductive polymer created with Panasonic's unique method as a cathode system. This enabled POSCAP to be thin, small and at the same time have low ESR (Equivalent Series Resistance) and superior high frequency characteristics. These features make POSCAP one of the best candidates for digital/high frequency applications. POSCAP also has high reliability and heat resistance.

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

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

4. Fire spreading to board
Safety measure
