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.

TRANSIENT VOLTAGE &  
CURRENT  
Fig P-11  
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.
