VISHAY PTCEL67R501TTE305

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 homogeneous high energy ceramic with increased switching temperature, 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, HEL on one side and date code on the opposite side.

• Higher energy absorption levels up to 340 J
• High number of inrush-power cycles: > 100 000 cycles e3
• Highly resistant against non-switching peak-powers of up to 25 kW
• RoHS COMPLIANT
• Can handle high direct voltage up to 1200 V
• Self protecting in case of overload with no risk of over-heating
