NTCG164LH333JT1 - TDK

NTCG164LH333JT1 Frequently Asked Questions (FAQs)

• What is the recommended soldering temperature and time for the NTCG164LH333JT1?
  The recommended soldering temperature is 260°C (500°F) for 10 seconds or less. However, it's essential to follow the soldering profile recommended by TDK Corporation or consult with their application engineers for specific guidance.
• Can I use the NTCG164LH333JT1 in a high-humidity environment?
  While the NTCG164LH333JT1 is designed to operate in a wide range of temperatures, it's not recommended for use in high-humidity environments (>80% RH) without proper protection. TDK recommends using a conformal coating or potting compound to protect the thermistor from moisture.
• What is the self-heating effect of the NTCG164LH333JT1, and how does it affect accuracy?
  The self-heating effect of the NTCG164LH333JT1 is approximately 1°C to 2°C (1.8°F to 3.6°F) at 1 mA current. This means that the thermistor's temperature reading may be affected by its own power consumption. To minimize this effect, use a low current (e.g., 0.1 mA) and ensure good thermal coupling to the target temperature.
• Can I use the NTCG164LH333JT1 for high-precision temperature measurement applications?
  While the NTCG164LH333JT1 has a high accuracy of ±0.5°C (±0.9°F) over a limited temperature range, it's not suitable for high-precision temperature measurement applications (e.g., ±0.1°C or better). For such applications, consider using a more precise thermistor or alternative temperature sensors.
• How do I handle the NTCG164LH333JT1's non-linear temperature response?
  The NTCG164LH333JT1 has a non-linear temperature response, which can be challenging to work with. To overcome this, use a look-up table or a thermistor curve-fitting algorithm to convert the thermistor's resistance reading to a temperature value. You can also use a microcontroller or a dedicated thermistor interface IC to simplify the process.
