Vishay Intertechnology, Inc. announced the launch has stronger stability, new series of SMD NTC thermistor ---NTCS....E3... SMT, can be used for temperature detection and compensation circuit. NTCS....E3... SMT thermistor capable of measuring temperature in -40 to +125 DEG C temperature range accurately, 10000 hours of work in the whole temperature range, resistance value relative to the initial resistance value under +25 DEG C (R25) of the maximum rate of change only + 0.5%.
SMD NTC thermistor with low initial electrical most tolerance through electrical properties after welding will change, will directly affect the accuracy of temperature measurement. But Vishay BCcomponents NTCS....E3... SMT devices in the series using non standard R25 value, in order to adapt to the ceramic material of thermistor stable resistivity and dimensions. This can keep the electrical characteristics of the initial throughout its life cycle, improve the precision of.
Thermistor today released the suitable thermal counter, thermometer and other medical applications, with 0402, 0603 and 0805 dimensions, each form has a R25 value. High R25 device values from 100k to 210K, reducing the self heating effect, this effect may lead to a temperature reading error.
NTCS....E3... SMT series single chip SMD thermistor with nickel grid and pure tin plating, in compliance with the RoHS, very suitable for wave soldering and reflow soldering. Device is arranged on a punched tape reel, each set was 4000 (0603 and 0805 dimensions) and 10000 (0402 dimensions) resistance.
