PTS120630V012

Ptc Resettable Fuses Overview

The PTS120630V012 is a surface-mount polymer PTC resettable fuse from the PTS1206 series, manufactured by Eaton Electronics. Designed for circuit protection in compact electronic assemblies, this component operates within a voltage range of up to 30 VDC and maintains a holding current of 120 mA. It trips at a current of 390 mA and features a maximum resistance of 15 Ohms. The device supports a maximum fault current of 10 A and functions reliably across an operating temperature range of -40°C to +85°C. Housed in a standard 1206 (3216 metric) SMD package with dimensions of 3.4 mm length, 1.8 mm width, and 1 mm height, it offers robust overcurrent protection for sensitive downstream components.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault conditions without manual replacement
• Offers reliable overcurrent protection through positive temperature coefficient behavior
• Compatible with standard surface-mount assembly processes for high-volume manufacturing

Ptc Resettable Fuses Applications

• Portable consumer electronics protection
• Automotive infotainment and sensor circuits
• Industrial control board input/output stages
• Communication equipment interface protection

Ptc Resettable Fuses Procurement Notes

Verify that the ordered part number matches the specific electrical ratings required for the target application, particularly the 30 VDC maximum voltage and 120 mA holding current. Confirm compliance with relevant safety certifications such as UL or TUV if mandated by the end-product design. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering to maintain component integrity during assembly.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require a 1206 footprint and the circuit demands protection against moderate overcurrent events up to 390 mA. Consider the 15 Ohm initial resistance impact on signal lines or low-voltage power rails. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range under worst-case load conditions.

Ptc Resettable Fuses Part Context

This part belongs to the PTS1206 family of self-resetting fuses, which are widely used in modern electronics for replacing traditional one-time fuses. The series provides various current and voltage combinations to suit different circuit densities. Eaton Electronics utilizes polymer technology to achieve fast response times while maintaining low profile dimensions suitable for dense PCB layouts.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 1206 PPTC devices with matching 120 mA hold current and 30 VDC rating, such as Bel Fuse 0ZCH0012FF2E or Littelfuse equivalents. Verify trip current and resistance values closely match to ensure identical protection characteristics.
