Type PTF Series
Thermometrics
PTC Thermistors
Description
Thermometrics PTF Series consists of a range of
radially-wired bare PTC disc thermistors.
Features
• Low cost solid state fuse
• Available in a broad range of resistances,
transition temperatures and voltage ratings
• Exhibits large positive increases in resistance
with temperature
• Resistance/temperature characteristic is
infinitely repeatable and has no hysteresis
associated with its action
• Proven quality and reliability over many years of
manufacturing
Applications
• Designed for general purpose over-current and
short-circuit protection
