Product details

12-Position Vertical FFC – BOM Fit and Board Layout

The 0.5 A per-contact rating and 50 V limit suit low-power signal paths inside a control board or display interconnect. The vertical orientation (contacts, vertical – 1 sided) means the FFC inserts straight down; the 5.10 mm height above board sets the clearance needed under the mating cable or a housing lid.

Vertical vs. Right-Angle – Which FMN for Your Board Edge?

The sibling 12FMN-SMT-A-TF uses the same 1.00 mm pitch and 0.5 A rating but mounts right-angle, bringing the FFC parallel to the board surface at a 3.00 mm height.

Cable Thickness and Termination Check

Tin contact finish on phosphor bronze base. Solder termination – the SMD pads reflow during standard lead-free profiles. No press-fit or through-hole anchor; the board lock relies on the solder joint alone for shear resistance from cable strain.

Frequently asked questions

What is the exact part number for a 12-position JST FFC connector?

Buyers need to confirm the MPN 12FMN-BMT-A-TF(LF)(SN) matches their BOM or replacement need.

Is the 12FMN-BMT-A-TF lead-free?

The (LF) in the part number indicates lead-free, which is critical for RoHS compliance.

What is the mounting type for 12FMN-BMT-A-TF?

Surface mount vs through-hole affects PCB design and assembly process.

Where can I buy 12FMN-BMT-A-TF with fast shipping?

Sourcing buyers need to find a distributor with stock and quick delivery to avoid production delays.

Does 12FMN-BMT-A-TF have a locking feature?

Locking ensures secure cable retention; spec shows none, which may impact application choice.

What is the recommended operating temperature for 12FMN-BMT-A-TF?

Temperature range is essential for reliability in harsh environments – not provided in basic specs, so buyers seek datasheet.
