F05054FA012M1WLJ9

Product Overview

This model is part of the “Ultra-Narrow Version” series, which utilizes a compact body width of only 4.9mm to save valuable PCB real estate. It is engineered with a front-flip (actuator) locking mechanism and a bottom-contact interface. To ensure mechanical stability and signal integrity, the assembly includes integrated left and right grounding clips.

Product Specifications

Pitch: 0.50 mm.
Height: 2.1 mm.
Body Width: 4.9 mm (Ultra-Narrow Version).
Number of Positions: 12 Pins.
Housing Material: White LCP (Liquid Crystal Polymer).
Actuator Material: Black LCP.
Terminal Material: Phosphor Copper.
Grounding Clips: Copper Alloy.
Contact Area Plating: Gold plating (1u” Min) over a Nickel underplate (50~100u”).
Solder Area Plating: Matte Tin (80~160u”).

Product Features

ZIF Flip-Lock Design: The front-flip actuator allows for zero-force insertion of the FPC, protecting delicate conductive gold fingers from mechanical wear during assembly.
Integrated Shielding: Features grounding clips on both sides to provide a secure grounding path for EMI reduction and increase mechanical solder strength.
Ultra-Narrow Profile: The 4.9mm width is ideal for high-density placement on multi-layered PCBs where space is extremely limited.
High-Temperature Reliability: Constructed with LCP thermoplastic, making it fully compatible with standard lead-free reflow soldering processes.
Superior Conductivity: Selective gold plating in the contact area ensures low contact resistance and long-term environmental durability.

Applications

Given its 12-pin configuration and ultra-narrow profile, this connector is commonly used in:

Wearable Technology: Smartwatches, fitness trackers, and miniature medical sensors.
Compact Displays: Connecting small LCD or OLED panels to main control boards.
Mobile Devices: Internal signal routing for smartphones and handheld digital cameras.
Automotive Sensors: High-density sensor interfaces within dashboard or infotainment modules.

Packing Details

Packaging Type: Vacuum Packaging.
Function: The vacuum seal protects the gold-plated terminals and LCP housing from environmental moisture and oxidation during transit and storage.

FAQ (Frequently Asked Questions)

1. Does the F05054FA012M1WLJ9 provide grounding for signal integrity?

Yes, this connector is designed “with grounding functionality” and includes integrated left and right copper alloy clips to provide a secure grounding path and help manage electromagnetic interference.

2. Which direction should the FPC conductive gold fingers face during insertion?

This model utilizes a bottom-contact design, meaning the conductive traces of the FPC must face downward toward the PCB surface upon insertion.

3. What is the benefit of the “Ultra-Narrow” body width?

The 4.9mm ultra-narrow width (compared to the 6.0mm narrow or 8.0mm wide versions) allows designers to save significant PCB space, making it perfect for ultra-slim mobile and wearable electronic designs.
