PFSM.150.2

Ptc Resettable Fuses Overview

The PFSM.150.2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the PFSM series manufactured by SCHURTER Inc. This component functions as an overcurrent protection device that automatically resets after cooling, eliminating the need for replacement following fault conditions. It is designed for board-level integration in electronic circuits requiring reliable thermal and electrical protection against excessive current flow.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit interruption during overcurrent events to protect downstream components
• Self-resetting functionality restores conductivity after the fault condition clears and the device cools
• Designed for surface-mount technology (SMT) integration onto printed circuit boards

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection of battery-powered equipment circuits
• Surge protection in consumer electronics assemblies

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix codes against official SCHURTER documentation to confirm exact rated current and voltage specifications. Ensure the ordering part number matches the required hold current and trip characteristics for the target application. Confirm RoHS compliance status through the manufacturer's datasheet rather than assuming standard attributes.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current and trip current ratings relative to the operating environment. Consider the maximum voltage rating and the ability to withstand peak pulse currents without permanent damage. Evaluate the physical footprint constraints for surface-mount placement and the thermal management requirements of the host PCB design.

Ptc Resettable Fuses Part Context

This part belongs to the PFSM series of self-recovery fuses produced by SCHURTER Inc. The series utilizes polymeric positive temperature coefficient technology to provide resettable overcurrent protection. These devices are engineered for high reliability in compact electronic designs where space efficiency and maintenance-free operation are critical requirements.

Ptc Resettable Fuses Replacement Considerations

Consult official substitution guides or cross-reference tables provided by SCHURTER for verified equivalent parts. Do not assume compatibility with generic PTC fuses from other manufacturers due to potential differences in trip characteristics and thermal response times.
