Key features of PTC Ni-Fe alloy NF60 include:
Applications:
1. **Temperature Sensors**: NF60’s positive temperature coefficient (PTC) behavior makes it ideal for use in temperature sensors, where it helps monitor and regulate temperature changes in automotive, industrial, and HVAC systems.
2. **Thermistors**: The alloy is commonly used in thermistors for applications that require temperature-sensitive resistance, such as in home appliances, medical devices, and industrial equipment.
3. **Self-Regulating Heating Elements**: NF60 is used in heating elements that automatically adjust their heat output based on temperature changes, found in devices like electric heaters, defrosters, and warming systems.
4. **Overcurrent Protection Devices**: The alloy is used in fuses, circuit breakers, and other overcurrent protection devices, where its resistance increases with temperature to limit current flow and prevent damage due to overheating.
5. **Battery Management Systems**: In battery-powered devices, NF60 helps regulate temperature and protect against overheating, ensuring safe and efficient performance in electric vehicles, portable electronics, and other battery-driven systems.
6. **Current Limiting Devices**: NF60 is used in current limiting applications, where its resistance change with temperature helps to prevent excessive current and protect sensitive electronic components.
These applications leverage NF60’s PTC properties, providing reliable, self-regulating thermal management and protection in a variety of industries.
