Description
The TDK-Lambda DFP10112 is a high-performance, integrated Thermal Cut-off / Resistor Assembly designed to provide mission-critical overheat protection. By combining a durable cement resistor with a precise, fusible alloy-type thermal cut-off, this device ensures reliable circuit interruption in the event of malfunction.
Engineered for robustness, it utilizes precision coil-winding technology, allowing it to withstand significant inrush currents without degradation. Upon reaching its activation temperature of 139°C, the unit permanently opens the circuit, preventing thermal runaway and secondary damage. Post-activation, the assembly maintains exceptional electrical insulation and voltage-withstanding properties, ensuring maximum safety and no risk of re-continuity or residual resistance issues.
Key Features
- Dual-Function Protection: Integrated cement resistor and fusible alloy thermal cut-off in a single, space-saving assembly.
- High Surge Tolerance: Coil-wound resistor design offers superior resilience against high inrush currents.
- Reliable Thermal Shutdown: Precisely calibrated to open the circuit at 139°C, providing a definitive safety barrier.
- Robust Post-Activation Safety: Maintains excellent dielectric strength after functioning, with zero risk of intermittent re-continuity.
- Industrial Grade: High-performance construction suitable for demanding applications requiring both resistance and thermal protection.
Package Includes
- 1 x TDK-Lambda DFP10112 Thermal Cut-off Resistor Assembly (10R, 139°C)
