MPTS0805L020R

Ptc Resettable Fuses Overview

The MPTS0805L020R is a polymeric positive temperature coefficient (PTC) resettable fuse manufactured by Meritek Electronics. Designed for surface mount applications in the 0805 package, this component serves as an overcurrent protection device. It operates within a voltage range of up to 9V and features a hold current rating of 0.2A. The device exhibits rapid tripping characteristics compared to standard SMD devices and offers lower resistance values. It is compliant with RoHS standards and halogen-free, suitable for high-density circuit designs.

Ptc Resettable Fuses Feature Summary

• Polymeric PTC technology providing resettable overcurrent protection
• Surface mount construction optimized for high-density PCB applications
• Faster trip time and lower resistance compared to standard SMD fuses
• RoHS compliant and halogen-free manufacturing

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices
• Protection for USB ports and data lines
• Battery pack protection circuits
• General purpose circuit protection in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific hold current and trip current parameters against the official Meritek datasheet for the MPTS0805L020R variant. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS and halogen-free specifications if required by your assembly process. Cross-reference the maximum operating voltage to ensure it meets the circuit design constraints.

Ptc Resettable Fuses Selection Notes

Select the MPTS0805L020R when a compact, surface-mount solution is required for low-voltage overcurrent protection. Consider its faster response time relative to standard fuses for sensitive components. Evaluate the 0.2A hold current against the normal operating current of the protected circuit to prevent nuisance tripping. The 0805 form factor is ideal for space-constrained layouts where through-hole components are not feasible.

Ptc Resettable Fuses Part Context

This component belongs to the Meritek MPTS series of polymeric PTC resettable fuses. The series includes various package sizes such as 0805, 1206, 1210, 1812, and 2920 to accommodate different current and space requirements. The MPTS series is characterized by its ability to automatically reset after fault conditions are cleared, offering a reusable alternative to traditional one-time fuses in modern electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes may include other 0805 PTC fuses with equivalent 0.2A hold current and 9V maximum voltage ratings from manufacturers like Bourns or Littelfuse. Verify that any replacement maintains the same trip time characteristics and package dimensions. Ensure the alternative part also meets RoHS and halogen-free requirements if applicable to your supply chain standards.
