Save up to 50% on time-delay & fast-acting fuses. We teamed with Edison Fuse(Cooper Industries subsidiary) to offer these fuses/fuse holders. All fuses are cross referenced as replacements for name-brand fuses like Littelfuse, Ferraz, Siemens. Fuses can protect transformers, motors, DC power supplies, lighting circuits, contactors, relays & other electrical equipment. (read more)

Spectrum Sensors and Controls introduces a high power, compact heater design that utilizes proven ceramic PTC technology to act as the heating element. The PTC thermistors used in this high power heater are self-regulating elements that can operate at a nearly constant temperature over a wide range of voltage and environmental conditions.

PPTC resettable fuses are produced with a patented Polymeric PTC (PPTC) material in thin chip form. It provides over current protection. At normal operating condition it remains at a low resistance and allows the electrical current to flow through without restriction. When overcurrent conditions occur, the PPTC material heats up and its resistance increase sharply. (read more)

The Cantherm YGM1 PTC thermistor is designed to function as a motor protector by transmitting the temperature of the windings to a receiving device. The YGM1 exhibits an exponential increase in resistance when the target temperature is reached, please see our website for detailed information. (read more)

Digi-Key is now stocking the complete range of Cantherm SDJ1 15A/250V thermal fuses. (read more)

Function Principle - The PTC (Positive Temperature Coefficient) is a temperature sensitive semiconductor, which is made of doped polycrystalline ceramic on the basis of barium titanate. The resistance of these thermistors increases sharply when a defined temperature is reached. This property is the reason for the self-regulation characteristic, which the PTC heating elements make use of. (read more)
