PTC Thermistors Product Index
	Self-Regulating Heaters Positive Temperature Coefficient thermistors are truly remarkable for their ability to function as self-regulating heating elements.		Over-Current Protectors Positive Temperature Coefficient thermistors are used in a wide variety of applications to protect sensitive components against Over-Current conditions.
	Single Sided Heaters With the single sided heater design, the bottom side of the thermistor element is electrically isolated from the top side.		Motor Protection Sensor Designed to provide economic and reliable overtemperature protection for three-phase motors, this assembly utilizes a small PTC disk that has a low base resistance.
	SMD PTC for Overload Protection Spectrum Sensors & Controls' surface mount PTC thermistor for overload protection combines a pair of rugged disk PTC thermistors with a surface mount leadframe that permits reliable and cost effective overload protection in a package that is easy to install with standard pick and place equipment.		PTC High Power Heater This high power heater assembly utilizes one or more PTC heating elements sandwiched between rigid aluminum fins that serve to maximize the heating surface area as well as protect the PTC elements.
	PTC Surface Heater Spectrum Sensors & Controls' PTC Surface Heaters are compact heating devices that utilize proven ceramic PTC technology to act as the heating element.	PTC Technical Notes Application Notes Engineering Notes
