CUSTOM PTCR PELLET
DESIGN CAPABILITY
Vishay Cera-Mite will customize
solid state overcurrent protector
PTCRs to your exact requirements
for telecommunication, power
supply, or general electronic
use. Providing great flexibility to
establish specific voltage, hold
current, time-trip characteristic, and
ambient temperature values.
Each device must be evaluated
and ratings established per appli-
cation. Mechanical packaging
influences performance ratings.

TRANSIENT VOLTAGE &
CURRENT
Because of the thermal storage
capacity of the ceramic PTCR,
transient surges do not cause tripping.
The PTCR is considered to be
transparent to these low energy
transients.
Fig P-11
shows a typical
test circuit for such transients.
