Seiko's thinnest and smallest chip-type electrical double-layer capacitor

CPH3225A is Seiko's thinnest and smallest chip-type electric double-layer capacitor. The unique ceramic packaging with superior air-tightness is used. As a result, it offers leakage and humidity resistance. Also, by optimization of the materials, max. 3.3 V charging is possible.

Heat-resistant design allows for Pb-free reflowable SMT board attachment.
