2920L600/16MR-A

Ptc Resettable Fuses Overview

The Littelfuse 2920L600/16MR-A is a POLY-FUSE surface-mount polymer PTC resettable fuse designed for circuit protection. It features a holding current of 6 A and a trip current of 12 A, rated for a maximum voltage of 16 VDC. The device has an initial resistance of 4 mOhms minimum and a post-trip resistance of 20 mOhms maximum, with a power dissipation rating of 2 W. It operates within a temperature range of -40°C to +85°C and is housed in a 2920 (7351 metric) package measuring 7.36 mm x 5.12 mm x 1.60 mm.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by increasing resistance as it heats during fault conditions
• Surface-mount design allows direct soldering to printed circuit boards for compact integration
• Self-resetting functionality restores normal operation after the fault condition is removed

Ptc Resettable Fuses Applications

• Protection of automotive actuators, screens, and small motors
• Overcurrent safeguarding for telecommunication and networking equipment
• Circuit protection for power supply components and wiring harnesses

Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified suppliers. Confirm that the received parts match the specific 2920L600/16MR-A designation and packaging format. Ensure compliance with RoHS3 standards and check moisture sensitivity level (MSL 2A) handling requirements prior to assembly. Validate datasheet specifications against current manufacturer documentation to confirm performance parameters.

Ptc Resettable Fuses Selection Notes

Select this component when a 6 A holding current and 16 VDC rating are required for surface-mount applications. The low initial resistance of 4 mOhms minimizes voltage drop in normal operation. Consider the 2920 package dimensions for PCB layout constraints. Evaluate thermal management needs given the 2 W power dissipation rating and operating temperature limits between -40°C and +85°C.

Ptc Resettable Fuses Part Context

This part belongs to the POLY-FUSE 2920L series of resettable fuses from Littelfuse. These devices utilize polymer technology to provide solid-state overcurrent protection. The series offers various current and voltage ratings optimized for automotive, telecom, and general electronic circuit protection applications requiring reliable, self-resetting safety mechanisms.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 2920L series variants such as 2920L500/16MR for lower current requirements. Verify that substitute parts maintain identical voltage ratings, package dimensions, and electrical characteristics to ensure compatibility.
