PTC Thermistors, Application Notes. bility of these ceramic PTC thermistors. Figure 5 Switching times tS of some PTC thermistors (parameter: different geometries) versus switching current IS (measured at 25 °C in still air) Application notes Please read Important notes Page 5 of 16 and Cautions and warnings.
Positive Temperature Coefficient. A PTC thermistor is a thermally sensitive resistor whose resistance increases significantly with temperature. Characteristics of PTC thermistors. Switching PTC thermistors are usually made of poly-crystalline ceramic materials that are highly resistive in their original state and are made semi-conductive by the addition of dopants. They are

Inrush Current Limiter 1. Brief of product A switching power supply has large inrush current when it turns on. If CPTC thermistor is used instead of a resistor or
PTC Thermistors. PTC ceramic thermistors have been proven reliable and effective over many years of use in a variety of over-current applications. Ceramic PTCs, unlike other PTC technologies, return to their same initial. R25 after being subjected to a fault condition. Ceramic PTCs can be switched again and again and will return to their initial value and are
PTC Thermistors For Switching Applications. Insufficient preheating may cause ceramic cracks. Rapid cooling by dipping in solvent is not recommended. Complete removal of flux is recommended. Standard PTC heaters are not suitable for soldering. Switching applications PTC thermistors in plastic case, 110 V and 230 V Please read Cautions and warnings and Page 8 of 12
Inrush Current Limiters. Ceramic Switching PTC thermistors are manufactured using a polycrystalline ceramic material that contains barium titanate, which has been doped with rare earth materials to give it positive temperature coefficient resistance.
