Ptc relay test
WebThe very high positive temperature coefficient (PTC) of the resistance above the reference tem-perature has given the PTC thermistor its name. Applicable standards are EN 60738-1, IEC 60738-1, DIN 44081 and DIN 44082. 3 Structure and function PTC thermistors are made of doped polycrystalline ceramic on the basis of barium titanate.
