Vishay PTCEL series precharge protection PTC thermistors

Vishays PTCEL series PTC thermistors offer a 60Ω to 1000Ω resistance range, 1000V high voltage, and 40A maximum inrush current. PTCEL thermistors are AEC-Q200 qualified and have a positive temperature coefficient and are primarily intended for inrush current limiting and overload protection. These thermistors are self protecting in case of overload with no risk of overheating and have high energy absorption levels up to 240J. Vishay PTCEL PTC Thermistors are ideal for power inverters, discharge - charge circuits, and smoothing and DC-link capacitor banks.

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.
