PF-140 PCB RFID Tag, 18 × 18 mm F08

PF-140 is a square PCB RFID tag for an OEM assembly that needs a small, rigid identifier inside its housing. The specified footprint is 18 × 18 mm, with an F08 chip operating at 13.56 MHz. The PCB form gives the mechanical designer a defined square area to accommodate, unlike a flexible inlay that can be shaped around a curve.

A phone reading distance of 25 mm is listed. The record does not identify a phone, exact RF protocol or application commands for that measurement, so validate the intended transaction on the target device. The chip designation alone is not a complete reader or software compatibility statement, and this listing does not assign an inferred memory size or security level.

The description permits embedding in silicone or plastic and mentions resistance to heat, pressure and corrosion. It provides no numerical limits for those conditions, no thickness and no ingress grade. Establish the physical build and encapsulation process with the supplier before setting an industrial operating requirement around the tag.

Use the 18 × 18 mm footprint when planning a sample fit, then test with the final covering material and reader position. The available information does not state how the tag is attached or what gap is needed behind it, so include those mechanical details in the sample specification. Approve the exact chip identification and data format alongside the mechanical design, since those details determine whether the completed object will work in the intended identification workflow.
