Thermistors

TDK Thermistors include negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors. The NTC thermistors offer a nickel barrier termination and long-term stability in high-temperature and high-humidity environments. The PTC series features thermally sensitive semiconductor resistors made of ceramic components in which electrical resistance rapidly increases when a certain temperature is exceeded. EPCOS / TDK Thermistors provide voltage and noise suppression as well as temperature measurement and compensation in measurement and control engineering, entertainment, household and automotive electronics, data systems, and telecommunications applications.
