2920L600/12MR-A

Ptc Resettable Fuses Overview

The Littelfuse 2920L600/12MR-A is a POLY-FUSE surface-mount polymer PTC resettable fuse designed for high-density circuit protection. It operates within a maximum voltage of 12 VDC and maintains a holding current of 6 A, with a trip current of 12 A. The device features a low initial resistance of 20 mOhms and supports a maximum fault current of 50 A. Housed in a compact 2920 (7450 metric) package measuring 7.98 mm by 5.44 mm with a height of 1.6 mm, it withstands power dissipation up to 2 W. The component functions reliably across an operating temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Self-resetting polymer PTC technology provides automatic circuit recovery after fault conditions clear
• Surface mount construction enables automated assembly on PCBs
• Low impedance design minimizes voltage drop during normal operation

Ptc Resettable Fuses Applications

• Portable electronic devices requiring overcurrent protection
• Consumer electronics circuits
• Battery packs and power management systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'A' against the manufacturer datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to soldering. Confirm availability through authorized distributors as supply status may vary.

Ptc Resettable Fuses Selection Notes

Select this component when a 12 VDC system requires a 6 A holding current with a 2920 form factor. Evaluate thermal derating curves to ensure the 2 W power dissipation rating accommodates ambient temperatures. Compare trip characteristics against load surge profiles to prevent nuisance tripping during startup.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse 2920L series of POLY-FUSE resettable fuses. The series offers various current ratings within the same 2920 surface mount footprint, allowing designers to scale protection levels without altering board layout dimensions significantly.

Ptc Resettable Fuses Replacement Considerations

Consult official Littelfuse documentation for verified cross-reference part numbers. Do not substitute based solely on physical dimensions; verify electrical parameters including holding current, trip current, and voltage ratings match the original design requirements.
