lnsk16 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 lns v 16 g 103 j p 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. series b constant z 3250k k 3435k y 3670k w 3890k a 3970k v 4150k u 4550k t 4750k chip size (mm) 10 1.0 x 0.5 x 0.5 (inches 0402) 16 1.6 x 0.8 x 0.8 (inches 0603) 20 2.0 x 1.2 x 0.8 (inches 0805) resistance at 25 ? 101 10 ?? 10 1 = 100 102 10 ?? 10 2 = 1 k 103 10 ?? 10 3 = 10 k package p paper taping e emboss taping b bulk resistance deviation range f ? 1 h ? 3 j ? 5 k ? 10 ordering information b constant deviation range f ? 1% g ? 2% h ? 3% product specification 1 of 4 4008-318-123 sales@twtysemi.com http://www.twtysemi.com
