B59118C1120A-EPCOS

The B59118C1120A is a ceramic-based temperature sensor that exhibits a rapid increase in resistance when it reaches its reference temperature. This behavior makes it ideal for protecting circuits against overheating. It is specifically optimized for applications where high accuracy and long-term stability are required. As of late 2025, this specific part number is often categorized as obsolete by major distributors, with manufacturers recommending modern substitutes such as the B59880C0120A070 for new designs.
