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
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.
APPLICATIONS
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
