What are the key features of TFM-125-12-SM-D-LC?
- 50-position dual-row layout at 0.050" (1.27 mm) pitch packs high contact density into a 1.525 inch body length, ideal for space-constrained SMT designs
- 30 micro-inch gold over 50 micro-inch nickel mating contact finish provides superior wear resistance and low contact resistance for high-reliability applications
- Split board lock mounting option mechanically secures the connector against vibration and lateral stress, enhancing robustness in industrial and aerospace PCB assemblies
What is TFM-125-12-SM-D-LC used for?
The TFM-125-12-SM-D-LC is engineered for high-reliability applications such as aerospace avionics, military electronics, and ruggedized industrial controllers that demand durable 0.050" pitch SMT connectors with gold-plated contact interfaces. Its 50-position dual-row configuration and split board lock are equally valuable in medical imaging equipment, FPGA development platforms, and high-speed data acquisition cards where mechanical stability and signal integrity must be maintained over extended operational lifetimes.

Frequently Asked Questions
What pitch and position count does the TFM-125-12-SM-D-LC offer, and why is this significant?
The TFM-125-12-SM-D-LC provides 50 positions at a 0.050" (1.27 mm) pitch in a dual-row vertical SMT configuration. This fine pitch allows engineers to route 25 signals per row within a 1.525-inch body, delivering twice the density of standard 0.100" pitch connectors in the same board footprint.
How does the gold contact finish on the TFM-125-12-SM-D-LC improve longevity in demanding environments?
Mating contacts carry 30 micro-inches of gold over 50 micro-inches of nickel, while termination contacts use tin with a nickel barrier. The thick gold plating resists oxidation and wear for thousands of mating cycles, maintaining low contact resistance critical for high-speed digital signals in aerospace, defense, and medical equipment.
What does the split board lock on the TFM-125-12-SM-D-LC do for PCB assembly?
The split board lock mechanically anchors the connector body to the PCB, absorbing lateral and shear forces that would otherwise stress the solder joints during vibration or cable insertion events. This feature is especially important in vehicle-mounted electronics and industrial machinery operating under continuous vibration at frequencies up to several hundred Hz.
How does the TFM-125-12-SM-D-LC compare to standard 0.100" pitch connectors for high-density board designs?
Compared to 0.100" (2.54 mm) pitch alternatives, the TFM-125-12-SM-D-LC's 0.050" pitch roughly doubles the signal count per unit length, reducing board real estate requirements by approximately 50% for equivalent pin counts. This trade-off is justified in FPGA mezzanine cards and high-speed data acquisition boards where PCB area is limited and signal count exceeds 40 pins.
