FEATURES
• High energy absorption levels up to 240 J
• High number of inrush-power cycles:
> 50 000 cycles
• Highly resistant against non-switching
peak-powers of up to 25 kW
• Can handle high direct voltage up to 800 V
• Self protecting in case of overload
• No risk of over-heating
• Rugged construction
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
Inrush current limiting and load-dump resistor in:
• Smoothing and DC-link capacitor banks
• Power inverters
• Discharge - charge circuits
PTCEL thermistors of similar resistance and size may be
used in series and parallel combinations to obtain higher
energy absorption levels. PTCEL thermistors may not be
used in series connections to obtain higher voltage levels.
DESCRIPTION
These PTC inrush current limiting or energy absorbing
thermistors consist of a medium resistivity doped barium
titanate ceramic with copper clad steel wires lead (Pb)-free
soldered to the Ag metalized pellet. A high temperature
silicone coating covers the ceramic body and is marked with
the cold resistance value, logo, EL and date code.
PACKAGING
PTC thermistors are available in 100 pieces (PTCEL13) or
50 pieces (PTCEL17) bulk packed or tape on reel option
500 pieces on request.
