Description:
The Eaton Resettable Fuse PTSA181216V150 is a Polymer Positive Temperature Coefficient (PPTC) resettable fuse. This means it's designed to protect electronic circuits from overcurrent faults. Unlike traditional fuses that melt and need replacement, a PPTC fuse "trips" to limit current during a fault and then resets itself once the fault is removed and the device cools down.
Key Features:
- Resettable: Eliminates the need for fuse replacement after a fault.
- Surface Mount (SMD): Designed for surface mounting on printed circuit boards.
- Polymer PTC: Uses a conductive polymer that increases in resistance with temperature.
- Overcurrent Protection: Protects circuits from damage due to excessive current.
- Fast Trip Time: Reacts quickly to overcurrent conditions.
- Wide Range of Applications: Suitable for various electronic devices.
- Compact Size: Small footprint due to the 1812 package.
Applications:
- USB Ports: Protecting USB ports on computers and devices.
- Portable Electronics: Used in smartphones, tablets, and other portable devices.
- Battery Packs: Protecting battery packs from overcurrent and short circuits.
- Industrial Control Systems: Protecting sensitive electronic components.
- Automotive Electronics: Used in automotive systems for circuit protection.
- Consumer Electronics: Found in TVs, DVD players, and other home entertainment devices.
