Circuit Examples
The POSISTORr has the
following advantages over
Bimetal devices.
1. Noise free
2. No contact problems
3. Low price
The POSISTORr has the
following additional advantages
over Zener Diodes.
1. Reduced numbers of parts
used in circuits
2. Reduced process costs of
mounting parts on PCBs
3. Reduces occupied space,
helping high density PCB
mounting
More than two pieces of POSISTORr can cover multi
hot spots working with a comparator. Fig. shows basic
circuit idea to connect multiple POSISTORr in series.
When One POSISTORr detects overheat at least, a
comparator can work by the sharp temperature-
resistance characteristic. It easily allows changing a
number of POSISTORr or sensing temperature in the
same basic circuit design.

Temperature Sensor Thermo String Type
1. High accuracy and highly sensitive temperature
sensing is mode possible by the small size and high
accuracy NTC Thermistor.
2. Narrow space temperature sensing is made
possible by the small sensing head and the thin
lead wire.
3. Flexibility and a wide variety of lengths (25mm to
150mm) enables the design of flexible temperature
sensing architectures.
4. This product is compatible with our 0402 (EIA) size
chip Thermistor.
5. Excellent long-term aging stability.
6. This is halogen free product.
* Cl=max. 900ppm, Br=max. 900ppm and
Cl+Br=max. 1500ppm
7. NXFT series are recognized by UL/cUL (UL1434,
File No. E137188).
