Overview
The EPCOS B59901D0090A040 is a high-precision Positive Temperature Coefficient (PTC) thermistor designed for critical temperature monitoring applications. Its primary function is to exhibit a significant, non-linear increase in resistance above a defined Curie temperature, enabling robust over-temperature detection. A key design consideration for engineers is the trade-off between response time and self-heating; while a lower thermal mass can improve speed, it also increases susceptibility to measurement errors caused by the thermistor’s own power dissipation, necessitating careful current limiting in the sensing circuit.
Key Features
- PTC Thermistor Type
