Product details

40-position 0.50mm-pitch FPC connector for dense board-level signal routing

The 5027904091: It uses a bottom-contact design with a flip-lock ZIF actuator, accepting 0.30mm-thick FPC cable. The right-angle surface-mount termination keeps the connector low-profile at 0.098" (2.50mm) above the board, suited for compact LCD or camera module interconnects.

0.5A signal-duty rating and bottom-contact orientation

Rated at 0.5A per contact and 50V, this connector is strictly for signal-level circuits—not power delivery. The bottom-contact configuration means the FPC's conductive pads face the PCB when inserted, which affects routing on the board. The 2.00µin gold plating on phosphor bronze contacts supports moderate mating cycles, typical for consumer or industrial display interfaces.

Flip-lock ZIF actuator and solder retention features

The double-contact feature improves reliability by providing two points of contact per pad.

Frequently asked questions

What FPC cable thickness works with the 5027904091?

This connector is specified for 0.30mm-thick FPC. Using a different thickness may compromise contact wipe or retention, leading to intermittent connections.

Is the 5027904091 suitable for high-flex applications?

The connector is designed for static installations—there is no evidence of dynamic flex rating. The ZIF clamp holds the FPC stationary, but repeated flexing of the cable near the connector could stress the solder joints. For high-flex applications, consider a connector with a strain-relief feature or a dedicated dynamic FPC.

What is the difference between bottom-contact and top-contact FPC connectors?

In a bottom-contact connector like the 5027904091, the FPC's conductive pads face the PCB when inserted. This means the circuit traces on the FPC must be on the side that contacts the connector's terminals. Top-contact connectors have the pads facing away from the PCB. The choice affects PCB routing and the FPC's orientation in the assembly.
