MPTS1812L010R

Ptc Resettable Fuses Overview

The MPTS1812L010R is a polymeric PTC resettable fuse manufactured by Meritek Electronics. It features a surface-mount 1812 package with concave geometry and tin terminations. The device operates within a temperature range of -40°C to 85°C and is RoHS compliant. Key electrical parameters include a maximum voltage rating of 60V, a hold current (Ih) of 100 mA, and a trip current (It) of 200 mA. Typical resistance at 25°C is specified as low ohmic values.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient construction for overcurrent protection
• Surface mount design with concave profile for PCB compatibility
• Halogen-free and RoHS compliant material composition
• Tin-plated dual-ended terminations for solderability

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices
• Circuit protection for battery-powered applications
• Protection for data interface lines
• General purpose circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'R' indicates the required tape-and-reel packaging configuration if automated assembly is intended. Confirm that the 1812 footprint matches the target PCB land pattern dimensions. Ensure the 60V rating and 100mA hold current align with the system's operational limits before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a compact, surface-mount overcurrent protector is required for low-voltage circuits. The 1812 size offers a balance between current handling capability and board space efficiency. Consider the trip current threshold relative to the normal operating current to ensure reliable protection without nuisance tripping during transient loads.

Ptc Resettable Fuses Part Context

This part belongs to Meritek's MPTS series of polymeric PTC resettable fuses. These components are designed to replace traditional fusible resistors or standard fuses in applications requiring automatic recovery after fault conditions. The series utilizes polymer technology to provide fast response times and high cycle life.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with MPTS1812L014R for higher current requirements. Verify equivalent ratings from other manufacturers such as Bourns or Littelfuse if supply chain diversification is necessary.
