Measurement direction 3.1 Technical performance Characteristic How to measure resistance <Caution at measuring the resistance value> The resistance value of this product changes very much by the temperature change. (Refer to the following table) Therefore it's important to be small fluctuation of the measurement environmental temperature at measuring the resistance value. POINT1 : Please measure the resistance value without touching a device and a substrate by hand or finger directly. POINT2 : Please install a thermometer at your measuring place in order to recognize the environmental temperature. Murata s website explains it by using video in following URL, so please check it. (For Example) Resistance value changes Murata P/N : FTN18XH103F01RT :10kΩ+/-1%, B-constant : 3380K+/-1%) Resistance value change approx.4% per 1degC difference around 25degC 6 / 15
