Ptc Resettable Fuses Procurement Notes

Verify the specific voltage rating requirements, as datasheets indicate both 30 V and 60 V variants exist within the series. Confirm that the 60 V specification aligns with your system design before procurement. Ensure the radial lead spacing matches your printed circuit board layout constraints. Cross-reference the manufacturer part number to distinguish between different voltage ratings in the PFRX family.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable protection mechanism is required for low-voltage DC circuits. The 1.35 A holding current suits moderate load protection needs. Consider the 60 V rating if operating above standard 30 V levels. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range. Verify compatibility with reflow soldering processes if applicable.

Ptc Resettable Fuses Part Context

This component belongs to the PFRX series of resettable fuses from Schurter. The series includes various current ratings and voltage options. The PFRX.135 specifically addresses the 1.35 A requirement within the higher voltage segment of the lineup. It serves as a reusable alternative to traditional one-time fuses in consumer electronics and industrial control systems.
