Enamelled Wire NTC Thermistor Electronic Thermometer and Battery
Brief Instruction:
The enamelled wire NTC thermistor is manufactured from Hefei Jingpu
Sensor Technology Co.,Ltd. The enamelled wire NTC thermistor is
consist of enamelled wire, NTC chip and epoxy resin. The optional
resistance value range from 0.3kΩ to 2000kΩ, and beta value range
from 2500K to 4500K. The enamelled wire NTC thermistor apply for
the electronic clinical thermometer, electrical medical device and
temperature measurement in battery.
Features:
Comply for RoHS standard
Miniature design
Fast thermal response time
Excellent long-term stability
Alternative lead lengths on request
Application:
Electronic clinical thermometer
Electric medical device
Temperature measurement in battery

Standard packing (inner packing): 500pcs/polybag
Operation Notice
1.Application:Temperature measure and control；
2.The current flowing through the NTC is controlled within the Pmax
range to avoid the measurement error caused by the self-heating of
the component.
3.Avoid excessive heat shock,The hot air blow should beat least 30mm
to the probe in case heat shrink protection tube need to be
attached.
4.Storage Temperature -10℃～40℃,≤75%RH；Avoid in a corrosive gas and
sunlit environment; After opening the package, it needs to be
sealed again.
5. According to the structure of Glass coating NTC thermistor, when
end user install, to avoid the epoxy head subjected too much
tensile force and bending force from the lead wire,The lead wire
shall be controlled at a bending point or a force point on a lead
wire 6mm or less below the sealing head.So as not to hurt the chip,
resulting in resistance drifting and even open circuit, esepcially
when the component is heated.
