Chip
type Electric Double Layer Capacitor
CPH3225A / CP3225A
CPH3225A/CP3225A is thinnest and
smallest chip-type electric double layer
capacitor.
The unique ceramic packaging with superior
air-tightness is used. As the result, it offers
leakage resistance and humidity resistance.
Also, by optimizing its materials, a 1 minute
rapid charge stores approximately 90% of
full capacity.
Its heat-resistant design allows for Pb-free
reflowable SMT board attachment.
FEATURES
Small and thin size
RoHS directive compliant
Pb free reflowable: 260deg.C peak
WEEE not applicable
Rapid Charge
Long Cycle Life
APPLICATIONS
Backup Power for various devices.
Super small size power supply.
Personal computer, IC card,
Game machine, Handy terminal, Video camera,
various kinds of small appliance, etc.

A few decades ago, we commercialized
a highly reliable silver oxide battery to meet
the requirement of quartz watch
development. Since then, we have
expanded our microbattery offering and
technology to support the increased
diversity in electronic products available
today.
This brochure introduces silver oxide
batteries, manganese silicon lithium
rechargeable batteries, titanium silicon
lithium rechargeable batteries, reflowable
lithium rechargeable batteries, and
reflowable capacitors.
We plan to continuously develop higher
performance microbatteries and widen our
products lineup to keep up with our
emerging technologies.
Please feel free to contact us with any
questions you may have.
FEATURES
1. Superior leakage resistance
Even a slight leakage from a battery may interfere with the connections
made by the battery terminals, resulting in unstable device operation.
Seiko Instruments Inc. offers micro batteries that are highly
leak-resistant due to special sealing materials and processing
technologies.
2. Large capacity
In order to extend the operating time of devices with limited battery
space, the market demands high volumetric efficiency.
We offer large-capacity microbatteries developed with proprietary
technology utilizing high-purity materials.
3. Stable operating voltage
Carefully compounded ingredients allow each of our micro batteries to
have a stable operating voltage over both a wide temperature range
and depth of discharge.
4. High reliability
Our micro batteries are manufactured under an integrated system
featuring strict quality control, which starts with component
manufacturing, through assembly and on to rigorous out-going
inspection.
