POSISTORr for Circuit Protection
for Overheat Sensing Lead Type
5.0 max.
4.0 max.
PTFM type has been developed for protecting power
transistors, stereo main amplifiers, etc. from
overheating, and also for sensing the temperature of
other components which may be overheated.
The "POSISTOR" offers an excellent temperature sensing
ability, exhibiting a steep change in electrical
resistivity near the temperature setting. PTFL type is
suitable for use as an air temperature sensor.

■ Features
(in mm)
1. PTFM type is a screw-fixing type and PTFL type is a
lead type, therefore mounting is easy.
2. Compact and light design as well as excellent
thermal response

3. Solid-state construction withstands mechanical
vibration and impact sufficiently
4. Contactless operation provides a prolonged service
life, yet permits noiseless operation.
5. The operating point of "POSISTOR" is set on the
steepest point along the resistance-temperature
characteristic curve, thus performing the overheat
protective operation securely.

6. PTFM type and PTFL type have the same temperature
characteristic, providing a selection depending on
the mounting method.
