- Safety measure
Conductive products can solve the problem
1. Insufficient capacitance
Quantity/Cost reduction
Quantity/Cost reduction
- Capacitance of MLCC is reduced by Voltage application + Low temperature/High temperature
2. Squeaking / Micro vibration
Rudeness prevention Anti-vibration

(Generation of micro vibrations)
SP-Cap / POSCAP
No vibration 
3. Cracks
Crack prevention measure
Crack prevention measure
- MLCC is cracked by temperature/mechanical impact
4. Fire spreading to board
Safety measure
Safety measure
The red heat continues if MLCC is short-circuited.
- MLCC
- Fire broadly spread to the board around MLCC
- SP-Cap
- No red heat
- SP-Cap/POSCAP swells or burns, but less spreading of fire
Application to be used
SP-Cap is used in the following applications from the lineup of the low ESR.
Of course the conductive polymer characteristic (Temperature characteristics etc.) is included, too.
- A main purpose of use : Low ESR
The CPU power line of Server, Mobile PC and Video game
