It mounts surface-mount, right-angle, so the FFC cable enters parallel to the board surface — a common layout for tight z-height enclosures. The connector accepts 0.30mm thick FFC with contacts on the top side. The 0.118\" (3.00mm) height above board keeps the assembly low-profile. ## Rated for signal duty The housing is UL94 V-0 rated polyamide (PA6T, Nylon 6T), and the operating temperature range is -25°C to 85°C. The 04FMN-SMT-A-TF uses a Low Insertion Force (LIF) contact design — no actuator lever. The FFC is inserted straight into the top-contact slot and held by the contact spring force. Termination is solder to the board pads.","metaTitle":"04FMN-SMT-A-TF JST FFC Connector, 4 Pos, 1mm Pitch","metaDescription":"04FMN-SMT-A-TF JST FMN series FFC connector, 4 positions, 0.039\" (1.00mm) pitch, SMT right angle, tin contacts, 0.5A, 50V.

They share the same current rating, voltage, and FFC thickness, but the contact orientation is vertical (1-sided) rather than right-angle top-contact. They are not drop-in replacements — the board footprint and cable entry angle differ."},{"question":"Does 04FMN-SMT-A-TF have a locking feature?","answer":"No actuator or locking latch. The connector uses a Low Insertion Force (LIF) contact design where the FFC is held by spring tension from the tin-plated contacts.
