KTR03EZPJ333 - ROHM Semiconductor

KTR03EZPJ333 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ROHM recommends a thermal pad size of 2.5mm x 2.5mm with a minimum of 1oz copper thickness and a thermal via diameter of 0.3mm to ensure optimal thermal performance.
• How do I ensure the reliability of the thermistor in high-humidity environments?
  To ensure reliability in high-humidity environments, ROHM recommends conformal coating, potting, or encapsulation of the thermistor, and following proper storage and handling procedures.
• What is the maximum allowable voltage for the thermistor?
  Although the datasheet doesn't specify a maximum voltage, ROHM recommends limiting the voltage to 5V or less to prevent damage to the thermistor.
• Can I use the KTR03EZPJ333 for high-temperature applications above 150°C?
  While the thermistor is rated for operation up to 150°C, ROHM recommends consulting with their application engineers for high-temperature applications above 150°C, as the thermistor's accuracy and reliability may be affected.
• How do I calibrate the thermistor for high-accuracy temperature measurement?
  ROHM recommends using a 3-point calibration method, where the thermistor is calibrated at 0°C, 50°C, and 100°C, to achieve high-accuracy temperature measurement.
