1206L075/16WR

Ptc Resettable Fuses Overview

The Littelfuse 1206L075/16WR is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the POLYFUSE 1206L series. It provides overcurrent protection with a hold current of 75 mA and a trip current of 180 mA. The device features a maximum voltage rating of 16 VDC, an initial resistance of 0.35 ohms, and a maximum tripped resistance of 1.4 ohms. It withstands fault currents up to 100 A and dissipates 0.6 W. Operating within a temperature range of -40°C to +85°C, it utilizes SMD/SMT termination for PCB integration.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault conditions clear without manual replacement
• Offers dual-mode protection against both overcurrent and excessive temperature events
• Designed for surface mount assembly to optimize printed circuit board space utilization

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact overcurrent protection
• Battery-powered equipment circuits
• Data communication ports and interfaces
• Peripheral connection lines in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation to confirm the exact electrical ratings and packaging configuration. Ensure the procurement documentation matches the required voltage and current specifications for the target application. Confirm compliance with relevant environmental standards before finalizing orders.

Ptc Resettable Fuses Selection Notes

Select this component when circuit design requires a low-profile resettable fuse with a 16 VDC rating. The 75 mA hold current suits sensitive low-power signal lines. Verify that the 100 A maximum fault current capability aligns with the system's potential short-circuit levels.

Ptc Resettable Fuses Part Context

This part belongs to the 1206L family of self-resetting fuses manufactured by Littelfuse. The series is engineered for high-reliability applications where repeated fault exposure occurs. It serves as a robust alternative to traditional one-time fusible links in modern electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct replacements must match the 1206 package dimensions and 16 VDC voltage rating. Substitute parts should maintain equivalent hold and trip current characteristics to ensure proper circuit protection performance.
