Image of Vishay BC Components PTCEL Thermistors - Features and Benefits Continued

A designer can significantly reduce board space and component count by replacing inrush current limiting wirewound or thick film resistors with PTCEL thermistors. The PTCEL has built-in safety for overload, failing short-circuit bypass, or capacitor breakdown. They can be used in series/parallel networks to increase current limitation and energy absorption, but please note, they cannot use the series connections to try to increase the voltage rating. PTCEL can be resistance matched for series/parallel circuits to improve the energy distribution in series/parallel networks.
