As leading manufacturer for polymer capacitor technology, Panasonic has developed "SP Cap" since 1984.
Its full name is "Conductive Polymer Aluminium Electrolytic Capacitor" or "Specilty Polymer Aluminium Electrolytic Capacitor". However, we usually prefer its nick name "SP Cap".
What is SP Cap?
Simply speaking, SP Cap uses solid polymer electrolyte instead of commen liquid electrolyte.
Why SP Cap?
Thanks to high conductivity of the polymer, SP Cap has excellent following characteristics.
Super low ESR down to 2 mOhm
High ripple current up to 4 Arms
Stable characteristics at high frequencies
No dry out
No voltage derating
No short circuit
No ignition
...
Tantalum Replacement with SP Cap
Because of above-mentioned excellent technical points and especially stable pricing compared with tantalum, SP Cap is ideal solution for tantalum replacement.
