TM
The CC12H Series Joins an
Extensive Line-up of SMD
Circuit Protection Solutions
• Performance
The Cooper Bussmann® CC12H Series
provides good inrush withstand
performance coupled with the
cycling advantages of a ceramic solid
matrix construction. This fuse solution
offers a five second maximum opening
time at 250% rated current for protection
against harmful overload currents. It’s
a cost-effective solution for applications in
which high inrush currents and/or on-off
cycling are present.
• Extensive Offering
Cooper Bussmann has added a new
series to an already impressive offering of
1206 fuses. The CC12H, available from 1A
to 5A, joins a line-up of fast-acting (3216FF) and
time-delay (3216TD) fuses which provide performance
and ratings that are unique to the industry.
• Space Saving
This compact SMD Chip Fuse offers a significant
space savings over other SMD devices with similar
performance.
• Environmentally Friendly
The full line of CC12H fuses are lead-free and RoHS
compliant, and present no disposal issues at end
of life.

Application Notes
High inrush currents are often linked to the
initial powering up of an electronic device.
The high I2t values of the Cooper Bussmann
CC12H allow the end user to avoid nuisance
openings from high inrush currents and
provides additional protection against
uncertain current surges from the system.
The CC12H allows maximum protection
without oversizing of the fuse rating. In
addition, the solid matrix construction of the
CC12H provides the end user with rugged
cycling performance throughout the life of the
equipment.
