1206L016WR

Ptc Resettable Fuses Overview

The Littelfuse 1206L016WR is a surface-mount PolySwitch resettable PPTC fuse designed for overcurrent protection in low-voltage circuits. It features a 30 VDC maximum voltage rating and a 160 mA hold current. The device trips at 370 mA, with a maximum resistance of 4.5 Ohms after tripping. It supports a fault current rating of 100 A and dissipates up to 600 mW. Operating within a -40°C to +85°C range, it measures 3.4 mm x 1.8 mm x 1.45 mm.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by raising resistance as it heats to limit current flow during fault conditions.
• Offers automatic circuit restoration without requiring manual replacement after the fault condition is removed.
• Constructed from polymer technology to ensure consistent performance across specified temperature ranges.

Ptc Resettable Fuses Applications

• Protection of portable electronic devices and battery packs
• Overcurrent safeguarding for telecommunications equipment
• Circuit protection in automotive electronics applications

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix 'WR' corresponds to the required tape-and-reel packaging configuration intended for automated assembly processes. Confirm RoHS compliance status and lead-free soldering compatibility against the most recent manufacturer datasheet to ensure alignment with environmental regulations and manufacturing standards.

Ptc Resettable Fuses Selection Notes

Select this component when circuit design requires a 30 VDC rating and a 160 mA hold current threshold. Ensure the application environment remains within the -40°C to +85°C operating temperature range. Verify that the 100 A fault current rating exceeds potential short-circuit levels to prevent device failure.
