1206L035YR

Ptc Resettable Fuses Overview

The Littelfuse 1206L035YR is a surface-mount PolySwitch resettable fuse designed for overcurrent protection in low-voltage circuits. It features a hold current of 0.35A and a trip current of 0.7A, with a maximum voltage rating of 6VDC. The device utilizes polymer positive temperature coefficient (PPTC) technology to provide automatic reset functionality after fault conditions clear. Packaged in a compact 1206 footprint, it supports reflow soldering and offers reliable circuit protection without requiring manual replacement.

Ptc Resettable Fuses Feature Summary

• Automatic reset capability eliminates the need for manual fuse replacement after tripping events
• Polymer PPTC construction provides stable resistance characteristics across operating temperatures
• Leadless surface mount design enables compatibility with standard reflow and wave soldering processes

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact overcurrent protection
• Battery-powered equipment and power management circuits
• Communication interfaces and data line protection

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix 'YR' matches the required tape and reel configuration for automated assembly lines. Confirm that the 6VDC rating aligns with the target circuit's maximum operating voltage to ensure proper device function. Check RoHS compliance status against current environmental regulations for the intended market. Ensure storage conditions maintain device integrity prior to soldering.

Ptc Resettable Fuses Selection Notes

Select this component when circuit requirements demand a low-profile solution with automatic recovery from overcurrent faults. The 0.35A hold current suits applications with steady-state currents below this threshold but above normal noise levels. Consider the 6VDC limit for low-voltage systems where higher voltage ratings are unnecessary. Evaluate thermal derating curves if ambient temperatures exceed standard room conditions during operation.

Ptc Resettable Fuses Part Context

This part belongs to the 1206L series of resettable fuses, which are widely used in consumer electronics for bus protection. The series offers various current ratings within the same physical package to simplify supply chain management. As a PPTC device, it differs from traditional fusible links by providing reversible protection, reducing maintenance costs in inaccessible installations.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1206 package dimensions, 0.35A hold current, and 6VDC voltage rating. Verify that alternative manufacturers offer comparable trip time characteristics and residual resistance values. Ensure any replacement maintains the same safety certifications and mounting compatibility for existing PCB layouts.
