NTC Thermistor SMD
DESCRIPTION
The LNS series is manganese oxide based NTC thermistor,
which shows non-linear resistance-temperature behavior.
Multilayered structure has as high reliability as monoblock type,
even without protective glass coating, since the active electrode
and sensor layer is buried inside the ceramic body.
FEATURES
APPLICATIONS
Multilayer structure allows diverse resistance value in the
same B constant
Multilayer structure allows lower resistance at high B
constant.
Solder plating with Ni barrier gives high reliability for both flow
and reflow soldering.
Unified shape and tightly controlled dimension is fit to high
mounting speed.
Temperature compensation for crystal oscillator (TCXO)
Temperature compensation for Personal computer
Temperature detection for CPU and memory device
Temperature detection for battery pack
Temperature compensation for contrast of LCD

Resistance @ 25oC
The zero-power resistance at the standard temperature of 25oC. The zero-power resistance means the value of DC resistance of a thermistor measured at a specified temperature,
with electric load being kept so small that there is no noticeable change in the measured resistance by the influence of the applied electric load.
Bconstant 25 / 85
B = ln(R0/R1) / (1/T0 - 1/T1) Without special note, B constant is calculated from the resistance values at 25oC and 85oC [B25/85], which is the most common.
¥)‰
Dissipation constant (¥
Dissipation factor is defined as the ratio at a specified ambient temperature of a change in power dissipation in a thermistor to the resultant body temperature change.
¡⁄¥ = P/( T1 - 25oC ) mW/ oC
¡⁄P : dissipated power
¡⁄T1 : thermistor temp, 85¡ 0.1oC

Thermal Time Constant
The time necessary for an unloaded thermistor to vary its temperature by 63.2% of the difference between its initial and final temperatures. Initial temperature is 85¡ 0.1oC and final
temperature is 47.1¡ 0.1oC.
