p is the filled with lead shape (1: twist, 2: without twist).
ppp is the filled with Total-length codes. (25mm, 30 to 150mm interval 10mm, ex. 050=50mm)
Operating Current for Sensor rises Thermistor's temperature by 0.1°C
Rated Electric Power shows the required electric power that causes Thermistor's temperature to rise to 30°C by self heating, at ambient temperature of 25 °C.
Operating Temperature Range: -40°C to +125°C
NXFT15_1B Type(twist)
NXFT15_2B Type(without twist)
This product is a small flexible lead type NTC Thermistor
with a small head and a thin lead wire.
■ Features
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 (25 mm 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).
■ Applications
1. Temperature compensation for transistor, IC and
crystal oscillator in mobile communications
2. Temperature sensor for rechargeable batteries
3. Temperature compensation of LCD
4. Temperature compensation in general use of electric
circuits
