a certain ambient temperature. The Maximum power dissipation under
ambient temperature 25°C or less is the same with the rated maximum
power dissipation, and Maximum power dissipation beyond 25°C
depends on the right Decreased power dissipation curve.
Thermistor 1°C through self heat generation under stable temperatures.
Multilayer Chip NTC Thermistors (hereafter referred to as “Thermistors”) may fail in a short circuit mode or in an
open circuit mode, when subjected to severe conditions of electrical environmental and/or mechanical stress
beyond the specified “Rating” and specified “Conditions” in the Specification, resulting in burnout, flaming or
glowing in the worst case. The following “Precautions for Safety” and “Application Notes” shall be taken in your
major consideration for use.
Dissipation factor (mW/°C) = Power consumption of Thermistor
(1) Environmental conditions
(2) Mechanical conditions
The specified “Operating Temperature Range” in the Specifications is the absolute maximum and minimum
temperature rating. Every circuit mounting a Thermistor shall be operated within the specified “Operating
Temperature Range”. The Thermistors mounted on PCB shall be stored without operating within the specified
“Storage Temperature Range” in the Specifications.
Thermistors shall not be operated in excess of the “Maximum power dissipation”.
If the Thermistors are operated beyond the specified Maximum power dissipation, it may cause burnout and/or
damage due to thermal run away.
For temperature detection applications, the accuracy may be greatly influenced by self-heat generation and
the heat dissipation of the Thermistor, even if the Thermistor is operated under the specified Maximum Power
Dissipation. Check safety and reliability in your circuit.
The Thermistors shall not be operated and/or stored under the following conditions.
The resistance of the Thermistors varies dependent on ambient temperatures and self-heating. Note the
following points when measuring resistance values of the Thermistors during inspection or when considering
them for circuits.
(1) Measurement temp : 25±0.1°C
(2) Power : 0.10 mW max.
(a) Under direct exposure to water or salt water
(b) Under conditions where water can condense and/or dew can form
(c) Under conditions containing corrosive gases such as hydrogen sulfide, sulfurous acid, chlorine and
Under severe conditions of extreme vibrations or shocks.
ammonia
Measurement in liquid (silicon oil) is recommended for a stable measurement temperature.
4 terminal measurement with a constant-current power supply is recommended.
