Vishay PTCEL series PTC thermistors

These directly heated ceramic-based doped barium titanate thermistors have a positive temperature coefficient and are primarily intended for inrush current limiting and overload protection. They consist of a ceramic pellet soldered between two tinned CCS wires and coated with a UL 94 V-0 compliant high temperature silicone lacquer. The body is marked with the logo, cold resistance value, EL on one side and date code on the opposite side.

Features

• High energy absorption levels up to 150J and 240J
• High number of inrush-power cycles: > 100000 cycles
• Highly resistant against non-switching peak-powers of up to 25kW
• Can handle high direct voltage up to 1200V
• Self protecting in case of overload with no risk of over-heating
• AEC-Q200 qualified
• C-UL-US recognized under file E148885 for AC and DC use

Applicationst

• Inrush current limiting and load-dump resistor in:
  • AC-DC and DC-DC converters
  • Load dump and DC-Link circuits
  • Emergency discharge circuits
  • OBC, battery charging equipment
  • Motor drives
  • Welding equipment
• PTCEL thermistors have resistance values that can change instantly based on the applied voltage levels and varying body temperatures
