Chip NTC Thermistor Simulation
Why Do You Need This Simulation Tool?
Advantage 1: Save time and money on creating prototype boards
By pairing an NTC Thermistor with a resistor, you can achieve various temperature-voltage curves. This simulation tool can perform 10 different temperature/voltage simulations as shown in the figure on the right.
Advantage 2: Find the right thermistor for your design requirements, reducing potential issues
To use a NTC thermistor safely, you can check its own temperature rise. If self-heating exceeds the specified value within the usage temperature range, the NTC thermistor may heat up, and in the worst case, lead to a malfunction. For safe usage, please verify the recommended NTC thermistor and resistance value for each circuit by simulation in advance.
