What are the key features of TFM-131-01-FM-D-LC?
- High-reliability Tiger Eye contact design providing superior normal force and retention across 500+ mating cycles at 0.050 inch (1.27 mm) pitch
- Dual-row 62-position layout with low-clearance (-LC) profile enabling high-density interconnect in space-constrained PCB assemblies
- Gold-plated contacts with flush-mount (-FM) termination for reliable SMT reflow soldering and low-profile board attachment
What is TFM-131-01-FM-D-LC used for?
The TFM-131-01-FM-D-LC is engineered for high-reliability board-to-board signal interconnect in defense electronics, aerospace avionics, and industrial control systems requiring long service life at 0.050 inch pitch. Its low-clearance profile makes it ideal for compact multi-board assemblies such as radar signal processors and ruggedized computing modules. The Tiger Eye contact geometry ensures consistent mating force and electrical continuity across the full operating temperature range from -55°C to +125°C.

Frequently Asked Questions
What distinguishes the Tiger Eye contact technology in the TFM-131-01-FM-D-LC from standard cantilever spring contacts?
SAMTEC Tiger Eye contacts use a bifurcated spring design that delivers two independent contact points per pin, maintaining reliable electrical connection even when slight misalignment occurs. This geometry provides a minimum normal force of 100 grams per contact at 0.050 inch pitch, reducing the risk of intermittent connections compared to single-wipe cantilever contacts in high-vibration environments.
For what operating temperature range is the TFM-131-01-FM-D-LC rated, and how does this affect aerospace application suitability?
The TFM-131-01-FM-D-LC is rated for operation from -55°C to +125°C, covering the full military temperature range per MIL-STD-810. This makes it suitable for avionics line-replaceable units (LRUs), satellite subsystem boards, and airborne radar modules where ambient temperatures can swing from cold-soak at altitude to thermal dissipation peaks during high-duty-cycle operation.
How does the low-clearance (-LC) suffix of the TFM-131-01-FM-D-LC reduce stacked board assembly height?
The low-clearance (-LC) profile reduces the connector's standing height to approximately 2.54 mm above the PCB surface after SMT reflow. In a dual-board stack, this means total mechanical clearance between the two boards can be as little as 5 mm, allowing designers to fit the assembly into enclosures with internal height constraints of less than 10 mm.
