Product details

Board-fit and footprint

The 04FMN-SMT-A-TF is a 4-position, 0.039" (1.00mm) pitch FFC connector from JST's FMN series. 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.

Frequently asked questions

What is the closest functional second-source for 04FMN-SMT-A-TF?

The 04FMN-BMTTN-A-TF and 04FMN-BMT-A-TF(LF)(SN) are vertical-mount variants of the same 4-position, 1.00mm pitch FMN series. 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.

Does 04FMN-SMT-A-TF have a locking feature?

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. For vibration-prone applications, consider a ZIF (zero insertion force) connector with a locking actuator.
