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 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.

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 ¡⁄ : thermistor temp, 85¡ 0.1oC T1 Maximum power rating P This is the maximum handling power, keeping its temperature not exceeding the allowed maximum temperature for operation. ¡⁄Pmax = ¥(Tmax - Ta) ¡⁄¥:dissipation constant ¡⁄Ta:25oC ¡⁄ max:125oC T 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.
