1.Introduction
MF52 Pearl-Shape Precision NTC Themistor
is ethoxyline resin-enveloped thermistor in
Small size which is made from new material
and by new technique,so we have researched
and developed several kinds of products,
.according to the different application
fileds.2.Application：
·Air-condition Equipments ·Heating Apparatus ·Electric
Thermometer ·Liquid level Sensor ·Automobile
Electricity ·Electric Table-board ·Battery
of Mobile Telephone
3.Characteristics：
·High Testing Precision ·Small size,Fast Rasponse ·Steady
Operating For Long Time ·Good Quality of
Coherence And lnterchange
·Scale production ,high ratio of Features to
cost

Remark： ·The
first pane fills whith cade of
different diamension.The second pane
fi8lls with
Raed Resistance ,the third fills
with its precision symbol.
·B value（25/50℃）error：the
corresponding error is ±1%for which
the precision of the rated
resistance is ±1%,others is ±2%
·Besides,our corporation can
supply products according to the
demands of users.
Notice：
·The two ends of the lead wire
cannot endure too big pull because
of the Small size and soldered spot
in series of MF52.
·While solding,please soldering at
the distance of 5mm from the bottom
of wrie at least and the periodof
solding should be as short as
possible. |
