Web1.1 PTC Thermistors The silicon-based PTC thermistors, also known as silistors, are much more linear than the switching PTC or NTC thermistors. The linear PTC temperature coefficient (also known as α) ranges from 0.6%/K to 0.8%/K. As shown in Figure 2, the switching PTC’s resistance increases exponentially at the Curie temperature. WebPTC thermistors are available in 100 pieces (PTCEL13) or 50 pieces (PTCEL17) layered bulk packed or tape on reel option 500 pieces on request.
