Supply continuity Lifecycle transition and long-term availability support
Quality requirements Traceable sourcing and quality-management processes

Focused on FPGA and Programmable Logic Supply

FPGAX focuses on helping customers maintain access to critical programmable devices throughout the full component lifecycle. Whether the requirement is for a current design, an established production program, or an older platform facing component obsolescence, our goal is to provide a stable sourcing path and help customers maintain design and manufacturing continuity.

PTC Resettable Fuses FAQ

Can FPGAX source both active and end-of-life PTC Resettable Fuses components?

Yes. FPGAX supports sourcing for both active components and end-of-life or hard-to-find parts, with an emphasis on maintaining supply continuity for engineering and manufacturing programs.

Which programmable logic manufacturers does FPGAX support?

Our core sourcing coverage includes major FPGA and programmable logic manufacturers such as Xilinx, Intel/Altera, Lattice, Microchip, and QuickLogic, subject to specific part requirements and availability.

How does FPGAX help with component lifecycle changes?

We support customers through lifecycle transitions by helping locate current or legacy supply, reducing exposure to supply disruptions, and supporting long-term availability for designs that need to remain in production.

What quality and traceability standards does FPGAX follow?

FPGAX states certification to AS9120B, ISO 9001:2008, and ISO 14001 standards. Our sourcing services are structured around traceability, stable supply, and quality-management requirements.

What information should I provide for a PTC Resettable Fuses sourcing request?

Providing the manufacturer part number, required quantity, target delivery schedule, and any lifecycle or traceability requirements helps us evaluate the sourcing request more efficiently.
