Test Methods
11 Free Fall
12 Vibration
· Resistance (R25°C) fluctuation rate: less than ±1%.
· B-Constant (B25/50°C) fluctuation rate: less than ±1%.
· No visible damage at resin part.
NTC Thermistor shall be dropped without any force onto
concrete floor from 1 meter height one time.
NTC Thermistor shall be fixed to the vibration test equipment.
Vibration of total 1.5 mm amplitude, Frequency sequence of
10Hz - 55Hz - 10Hz in 1 minute, shall be applied for right
angled 3 directions for each 2 hours duration.

* · R25 is zero-power resistance at 25°C.
· B25/50 is calculated by zero-power resistance of Thermistor in 25°C -50°C.
· After each test, NTC Thermistor should be kept for 1 hour at room temperature (normal humidity and normal atmospheric pressure).
