PTC Radial Lead Types

NTE's PTC thermistors are small−sized radial lead organic silicon resin thermistors designed for overcurrent and overload protection.

Thermistors are available in two types: those with Negative Temperature Coefficients (NTC Thermistors, NTE 02-Nxxx series) and those with Positive Temperature Coefficients (PTC Thermistors, NTE 02-Pxxx series). An NTC Thermistor's resistance decreases as its temperature increases. A PTC Thermistor's resistance increases as its temperature increases. NTC Thermistors are more commonly used for temperature measurement while PTC Thermistors are primarily used for circuit protection.

Product Applications:

• Overload and Current Protection of Mini Voltage Transformer Primary Loops, Chargers, Safe Guard Unit and Thunder Surge Protection Circuit for Telecom Apparatus, and Industry−Controlling Exchangers
• Overcurrent Protection for Ammeters, Digital Multimeters, Micro−Electric Machinery, and Transistors
