MPTS1206L010R

Ptc Resettable Fuses Overview

The MPTS1206L010R is a polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Meritek Electronics. Designed in a surface-mount 1206 package, this component functions as an overcurrent protection device with a hold current of 0.1A and a trip current of 0.5A. It supports maximum voltages up to 60V and features a minimum initial resistance of 1.6 Ohms and a maximum post-trip resistance of 15 Ohms. The device exhibits a trip time of approximately 1 second under fault conditions.

Ptc Resettable Fuses Procurement Notes

Verify the specific voltage and current ratings against the target circuit requirements before procurement. Confirm that the 1206 package dimensions align with the PCB footprint design. Ensure the application environment remains within the specified operating temperature range to maintain reliable performance characteristics during normal operation and fault conditions.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable protection solution is required for low-current circuits up to 0.1A holding capacity. Consider the 1206 form factor for space-constrained layouts where standard axial fuses are unsuitable. Evaluate the thermal environment to ensure the device can dissipate heat effectively without nuisance tripping during normal load variations or startup surges.

Ptc Resettable Fuses Part Context

This part belongs to Meritek's MPTS series of polymeric resettable fuses, which utilize conductive polymer technology. These components provide robust overcurrent protection in a small surface-mount footprint. The series is designed to replace traditional fusible links in modern electronics, offering repeated protection cycles while maintaining consistent electrical characteristics throughout the product lifecycle.

Ptc Resettable Fuses FAQ

What is the difference between hold current and trip current for this device?

The hold current (0.1A) is the maximum current the device can carry indefinitely without tripping. The trip current (0.5A) is the minimum current at which the device will switch to a high-resistance state to protect the circuit.

How does the resistance change during operation?

The device has a minimum initial resistance of 1.6 Ohms. Upon tripping due to overcurrent, the resistance increases significantly, reaching a maximum post-trip resistance of 15 Ohms to limit current flow.
