The Low Insertion Force (LIF) design means the FPC slides into the contact slot without a separate locking actuator — the contact beams grip the FPC pads directly. This keeps the mated profile low at 3.00 mm above the board, useful where z-height is tight. ## Tin-Plated Contacts and LIF Retention Contacts are tin-plated phosphor bronze. The LIF retention relies on the contact beam spring force, not a secondary latch — the FPC is held by the normal force of the contacts against the pads. The housing is black polyamide (PA6T) rated UL94 V-0, and the connector accepts 0.30 mm thick FFC. The contacts are on the top side of the connector. Termination is solder — reflow the SMT pads to the board; no press-fit or crimp option. The base product number is 12FMN-SM — use this for cross-referencing mating FPC part numbers within the FMN series.","metaTitle":"JST 12FMN-SMT-A-TF(LF)(SN) FFC Connector – 1.00mm Pitch","metaDescription":"JST FMN series 12-position FFC connector, 1.00mm pitch, 0.5A, tin-plated contacts, LIF, surface-mount right-angle.
