Abstract (en)
An organic positive temperature coefficient thermistor comprises a thermoplastic polymer matrix, a low-molecular organic compound, and conductive particles, each having spiky protuberances thereon. The low-molecular organic compound has a melting point of 40 DEG C to 100 DEG C. The conductive particles are interconnected in a chain form. <IMAGE>
