PTSA120616V035

Ptc Resettable Fuses Overview

The PTSA120616V035 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Eaton Electronics. It belongs to the PTSAHT1206 series and features a 1206 (3216 metric) package with SMD/SMT termination. The device maintains a holding current of 350 mA and trips at 950 mA, operating within a maximum voltage of 16 VDC. It exhibits an initial resistance of 1.6 Ohms and withstands fault currents up to 50 A. The component operates reliably between -40°C and +125°C, dissipating 1 W of power, with physical dimensions of 3.5 mm length, 1.8 mm width, and 1.14 mm height.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through self-resetting PPTC technology upon cooling after fault conditions.
• Designed for surface mount integration using standard SMD/SMT PCB mounting techniques.
• Engineered for high reliability in automotive and industrial environments with extended thermal stability.

Ptc Resettable Fuses Applications

• Overcurrent protection for low-voltage DC circuits
• Protection of portable electronic devices and battery packs
• Automotive electronics and sensor circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required electrical ratings, particularly the 16 VDC maximum voltage and 350 mA holding current, to ensure compatibility with the target circuit design. Confirm compliance with RoHS directives and check for any specific automotive qualification requirements if the application demands it. Ensure the procurement source provides official documentation to validate the component's authenticity and manufacturing origin.

Ptc Resettable Fuses Selection Notes

Select this component when the application requires a compact, low-resistance overcurrent protector for 16 V systems. The 1206 footprint allows for space-constrained designs, while the 1.6 Ohm resistance minimizes voltage drop during normal operation. Consider the 50 A maximum fault current rating to ensure the device can handle potential surge events without permanent damage, ensuring long-term circuit integrity.

Ptc Resettable Fuses Part Context

This component is part of the PTSAHT1206 series from Eaton Electronics, specialized for high-temperature and high-reliability applications. Unlike standard PPTC fuses, this series is optimized for automotive use, offering enhanced performance under extreme thermal conditions. It serves as a reusable alternative to traditional one-time fuses, reducing maintenance costs and system downtime in critical electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other Eaton PTSAHT1206 series variants with matching 350 mA holding current and 16 VDC ratings. Cross-brand replacements require careful verification of trip characteristics and package dimensions to ensure board compatibility and equivalent protective performance.
