1210L050YR

Ptc Resettable Fuses Overview

The Littelfuse 1210L050YR is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the 1210L series. It features a 1210 (3225 metric) package and operates within a temperature range of -40°C to +85°C. The device has a holding current of 500 mA, a trip current of 1 A, and a maximum voltage rating of 6 VDC. It offers an interrupting rating of up to 100 A and a typical resistance of 0.2 ohms.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions by resetting after cooling
• Utilizes polymer PTC technology for reliable performance in compact surface-mount designs
• Offers bidirectional protection capabilities for various circuit configurations

Ptc Resettable Fuses Applications

• Portable electronic devices requiring overcurrent protection
• Battery packs and battery management systems
• Peripheral interfaces such as USB ports and data lines

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix YR indicates reel packaging when ordering. Confirm that the 6 VDC rating aligns with your system's maximum operating voltage. Ensure the 500 mA holding current meets the continuous load requirements without nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require a 1210 footprint. Choose based on the 500 mA holding current and 6 VDC maximum voltage limits. Consider the 1 A trip current threshold for fault detection sensitivity. Verify compatibility with standard reflow soldering processes for surface mount assembly.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse 1210L series of resettable fuses. These components are designed for circuit protection in low-voltage applications. The series provides a cost-effective alternative to traditional fuses by offering reusable protection against overcurrent events.

Ptc Resettable Fuses Replacement Considerations

Check for equivalent parts from other manufacturers with matching 1210 footprints. Ensure substitute components meet the same 500 mA holding current and 6 VDC voltage ratings. Verify that the replacement maintains similar trip characteristics and thermal performance.
