The recommended PCB layout involves keeping the thermistor pins away from high-current paths and using a solid ground plane to reduce thermal resistance. A thermal pad or heat sink can be added to improve heat dissipation. Consult the application note AN9313 from Littelfuse for more details.
To ensure accurate temperature measurement, ensure the thermistor is properly calibrated, and the measurement circuit is designed to minimize noise and thermal gradients. Use a high-precision analog-to-digital converter and consider using a thermistor with a built-in thermocouple for higher accuracy.
The GTCA25-750M-R02 has an operating temperature range of -40°C to 150°C, but the accuracy and stability of the thermistor may degrade above 125°C. Consult the datasheet for specific temperature-related specifications.
The GTCA25-750M-R02 is designed to withstand moderate vibration and shock, but it's essential to ensure proper mounting and mechanical support to prevent damage. Consult the application note AN9313 from Littelfuse for guidance on mechanical design and testing.
To minimize EMI and RFI, use proper shielding, grounding, and filtering techniques in the circuit design. Ensure the thermistor leads are properly routed and terminated to reduce electromagnetic radiation.
