Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'YR' against official Littelfuse documentation to confirm halogen-free status and tape/reel specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the datasheet revision date to confirm compliance with current regulatory requirements before finalizing orders.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, surface-mount resettable fuse is required for 15V systems. The 350 mA hold current suits moderate load protection needs. Verify that the 1206 footprint aligns with PCB layout constraints. Consider the 85°C upper temperature limit for thermal management in enclosed designs compared to higher-rated automotive variants.

Ptc Resettable Fuses Part Context

This part belongs to the PolySwitch® picoASMD family, which focuses on miniaturized circuit protection solutions. It complements other 1206L series fuses by offering specific electrical ratings tailored for low-voltage digital logic and peripheral protection. The series is widely recognized for its reliability in consumer-grade electronics manufacturing.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 1206L series fuses with matching 15V and 350mA ratings, such as the 1206L035/15HT-ND. Verify physical dimensions and electrical characteristics before substitution.
