What are the key features of TFM-109-03-F-D-RA?
- 18-position dual-row contact array at 0.050 inch (1.27 mm) pitch for compact, high-density signal connections
- Flat right-angle (F-RA) tail style routes signals horizontally along the PCB plane to minimize vertical stack height
- Tiger Eye stamped contact design provides consistent wiping action and low contact resistance across 500+ mating cycles
- High-reliability construction suitable for defense, industrial, and telecom applications requiring long service life
What is TFM-109-03-F-D-RA used for?
The TFM-109-03-F-D-RA is well-suited for edge-mounted signal breakout in embedded computing modules, test and measurement interfaces, and industrial I/O panels where the right-angle orientation routes 18 signals parallel to the board surface. Its 0.050 inch pitch keeps the connector footprint small enough for dense multi-connector panel layouts. The Tiger Eye contact reliability makes it a strong choice for field-serviceable boards in defense avionics and telecom equipment.

Frequently Asked Questions
How many positions does the TFM-109-03-F-D-RA provide, and how are they arranged?
The TFM-109-03-F-D-RA provides 18 positions in a dual-row configuration at 0.050 inch (1.27 mm) pitch, placing 9 contacts per row. This compact arrangement fits high-density signal routing for embedded module edge connectors and I/O panel breakout boards.
What benefit does the flat right-angle (F-RA) tail style provide in PCB system design?
The flat right-angle tail routes all 18 signal lines horizontally along the PCB surface, reducing the overall height above the board by the length of a vertical tail and enabling the connector to exit signals through panel slots in enclosures with vertical clearance limits below 10 mm.
How does the TFM-109-03-F-D-RA's Tiger Eye contact compare to standard press-fit or machined-pin alternatives?
SAMTEC Tiger Eye contacts use a stamped leaf geometry that wipes the mating surface during insertion, clearing oxide layers and achieving contact resistance below a few milliohms for more than 500 insertion cycles, which exceeds the typical 200-cycle rating of standard press-fit or low-cost machined-pin connectors used in similar 0.050 inch pitch applications.
In what industries and system types is the TFM-109-03-F-D-RA most commonly deployed?
The TFM-109-03-F-D-RA is most commonly used in defense avionics, industrial programmable logic controllers, and telecom small-form-factor blades, where 18-position dual-row right-angle connectivity at 0.050 inch pitch delivers robust signal paths in compact chassis and panel-mount assemblies with long service-life requirements.
