Additional Details

The B59008C0060A040 typically has a Curie temperature around 125°C. At temperatures below the Curie temperature, the resistance is low, allowing normal current flow. When the temperature exceeds the Curie temperature due to an overcurrent condition, the resistance rapidly increases, limiting the current and protecting the circuit. Once the fault is cleared and the thermistor cools down, the resistance returns to its low value, allowing normal operation to resume. The flame-retardant coating provides additional safety by preventing the thermistor from catching fire in the event of a severe overload. It is important to consult the manufacturer's datasheet for precise electrical characteristics, dimensions, and operating conditions to ensure proper application and performance. The leaded design allows for easy mounting and connection to the circuit board.

Important Note: Always refer to the official EPCOS (TDK) datasheet for the most accurate and up-to-date specifications before using this component in any application.
