The NAN0SMDC020F-2 is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse from TE Connectivity. This surface-mount device provides overcurrent protection by increasing its resistance dramatically when an overcurrent condition occurs, effectively limiting the current flow and protecting downstream components. Once the fault is cleared and power is removed, the device cools down and resets to its low-resistance state, allowing normal circuit operation to resume. The "020" in the part number indicates a hold current of 0.20 Amperes.

Applications

• USB ports: Used to protect USB ports from overcurrent conditions caused by faulty devices or short circuits.
• Battery packs: Employed in battery packs to prevent overcurrents during charging or discharging.
• Portable electronics: Implemented in portable electronic devices such as smartphones, tablets, and wearables to protect internal circuits from overcurrents.
• Power supplies: Used in power supplies to protect against overloads and short circuits.
• Automotive electronics: Employed in automotive electronic systems to protect sensitive components from overcurrent events.

Features

• Resettable: Automatically resets after the fault is cleared, eliminating the need for manual replacement.
• Surface-mount design: Allows for easy and efficient assembly on PCBs.
• Small size: Compact size allows for use in space-constrained applications.
• Fast trip time: Quickly responds to overcurrent conditions, providing rapid protection.
• Low resistance: Offers low normal operating resistance, minimizing power loss.

Benefits

• Protects against overcurrents: Prevents damage to electronic components caused by overcurrent conditions.
• Reduces downtime: Automatically resets after the fault is cleared, minimizing downtime.
• Simplifies maintenance: Eliminates the need for manual replacement of fuses, simplifying maintenance.
• Enhances system reliability: Improves the overall reliability of electronic systems by providing robust overcurrent protection.
• Reduces warranty costs: Prevents damage to products caused by overcurrents, reducing warranty costs.

Additional Details

The NAN0SMDC020F-2 has a hold current (Ih) of 0.20A and a trip current (It) significantly higher than the hold current. The trip time depends on the magnitude of the overcurrent. After tripping, the PPTC device will have a much higher resistance, limiting the fault current. It's crucial to select a PPTC device with appropriate voltage and current ratings for the specific application. Consult the manufacturer's datasheet for detailed electrical characteristics, tripping curves, and recommended soldering profiles. The component complies with RoHS requirements.
