Conductive Polymer Aluminum Electrolytic Capacitors (SP-Cap)

Zoom
"SP-Cap" is a rectangular chip-shaped aluminum electrolytic capacitor that uses a polymer as its electrolyte. SP-Cap has several features including low ESR, low ESL, long life span, small size, low profile, and high characteristic stability.

Topics

Features

  • Ultra-low ESR capacitor, top class in the industry
  • Stable temperature characteristics / Frequency characteristics
  • Lineup of 1.0-mm (max.) thick low-profile products
  • High safety made possible by self-recovery function (no ignition)
  • Low ESL type adopting three-terminal structure available

Measures against problems with electrolytic capacitors and general tantalum capacitors

  1. Noise measure
  2. Ignition measure
  3. Low profile / Space-saving

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.
