PTCEL Series Inrush Current-Limiting PTC Thermistors
Vishay's PTC thermistors provide safe repetitive inrush current limitation and protection in many high-power applications
Vishay's inrush current-limiting positive temperature coefficient (PTC) thermistors are designed to increase performance in active charge and discharge circuits for automotive and industrial applications. PTCEL high-energy series devices combine maximum energy handling of 340 J with a wide range of resistance at +25°C (R25) values and high-voltage capabilities. The devices’ increase in thermal capacity reduces the number of components required to save space, simplify designs and product development, reduce costs, and increase efficiency.
Features
