Instructions for Use:

1. Handling:

   • Handle with care to avoid mechanical damage.
   • Avoid exposure to corrosive environments.

2. Mounting:

   • Ensure proper mounting to maintain thermal contact with the environment or heat sink.
   • Use appropriate mounting hardware to secure the component.

3. Electrical Connection:

   • Connect the NTC thermistor in series or parallel as required by your application.
   • Ensure that the voltage across the thermistor does not exceed its maximum ratings.

4. Thermal Management:

   • The dissipation constant (δ) indicates the power dissipation capability. Ensure that the power applied to the thermistor does not exceed this value to prevent overheating.
   • The thermal time constant (τ) is the time it takes for the thermistor to reach 63.2% of the temperature change. This should be considered in dynamic temperature measurement applications.

5. Storage:

   • Store in a dry, cool place away from direct sunlight and sources of heat.
   • Keep in original packaging until ready for use to protect against static and physical damage.

6. Testing:

   • Measure resistance at room temperature (25°C) to verify the nominal value.
   • Use a beta calculation to determine the resistance at different temperatures if needed.

7. Application:

   • Suitable for temperature sensing, compensation, and protection in various electronic circuits.
   • Can be used in temperature control systems, overtemperature protection, and temperature monitoring applications.
