PTC Thermistors provide protection  
for large digital switches.Vishay Cera-  
Mite has pioneered this field with  
ceramic PTC thermistors working  
closely with major telephone equip-  
ment and telephone protection  
manufacturers. The requirements are  
dynamic, as switch makers continually  
strive to protect at lower levels.Vishay  
Cera-Mite participates with industry  
standard technical committees to  
establish common definitions and  
understanding of this new tech-  
nology.

INTERRUPTING CAPACITY ESTIMATES  
Under unusual circumstances, telecommunication lines may  
be subjected to high surge currents as might occur from  
lightning effects or accidental crossing with power lines or  
transformer primaries.
