Ptc Resettable Fuses datasheet and documents for PTSA181216V150

PTSA181216V150

Ptc Resettable Fuses Overview

The PTSA181216V150 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the Eaton Electronics PTSA1812 series. It features a 1.5 A hold current and a 3 A trip current, designed for circuits operating at a maximum voltage of 16 VDC. The device exhibits a typical resistance of 120 mΩ and can withstand a maximum rated current of 40 A. Packaged in an 1812 (4532 metric) SMD/SMT footprint with dimensions of 4.73 mm length, 3.41 mm width, and 1 mm height, it operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix and packaging configuration against the official datasheet before procurement. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the selected package type aligns with your automated assembly capabilities. Cross-reference the manufacturer part number with authorized distributor listings to guarantee authenticity and traceability.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, surface-mount solution is required for 16 VDC circuits. The 1.5 A hold current defines the continuous operating limit, while the 120 mΩ resistance impacts power dissipation. Evaluate the 1812 package dimensions against available board real estate. Consider the -40°C to +85°C operating range relative to the environmental conditions of the final application.

Ptc Resettable Fuses Part Context

This part belongs to the PTSA1812 series of resettable fuses manufactured by Eaton Electronics. The series utilizes polymeric technology to provide reusable overcurrent protection. These components are distinct from traditional fusible links as they restore conductivity after cooling following a fault event. The PTSA1812 form factor is standardized for high-volume surface-mount production lines.
