What are the key features of TFM-105-02-SM-D-LC?
- 10-position dual-row 0.050 inch (1.27 mm) pitch SMT vertical configuration for high-density signal routing in compact PCB footprints
- 30 microinch gold over 50 microinch nickel contact finish on phosphor bronze providing contact resistance below 10 milliohms and 500+ mating cycle reliability
- Split board lock (SBL) mounting feature mechanically secures the connector to the PCB, preventing lift-off under vibration or cable pull forces
What is TFM-105-02-SM-D-LC used for?
The TFM-105-02-SM-D-LC is designed for compact, high-reliability SMT board-to-board interconnect applications requiring 10 positions at 0.050 inch pitch in a vertical orientation. Its gold-plated Tiger Eye contacts and split board lock make it suitable for aerospace, military, and instrumentation PCBs where vibration resistance and low contact resistance below 10 milliohms are required over extended service life. The lead-free (LC) finish ensures RoHS compliance for commercial electronics production.

Frequently Asked Questions
What contact material and finish does the TFM-105-02-SM-D-LC use, and how does that affect mating cycle performance?
The TFM-105-02-SM-D-LC uses phosphor bronze contacts with 30 microinch gold plating over 50 microinch nickel on mating surfaces and tin-over-nickel on termination surfaces. This combination maintains contact resistance below 10 milliohms for over 500 mating cycles, making it reliable for test fixtures and serviceable board-to-board interfaces in instrumentation and aerospace electronics operating between -55°C and 125°C.
How does the split board lock on the TFM-105-02-SM-D-LC improve mechanical retention compared to solder-only SMT connectors?
The split board lock (SBL) on the TFM-105-02-SM-D-LC anchors the connector body to the PCB through two press-fit or solder-in board lock legs in addition to the SMT solder joints. This feature increases the pull-off force resistance to over 10 N per lock, preventing the 10-position 0.050 inch pitch connector from lifting off the PCB under cable tension, vibration loads, or repeated mating forces encountered in avionics, industrial machinery, and portable instrumentation.
For which compact PCB designs is the 10-position 0.050 inch pitch vertical SMT format of the TFM-105-02-SM-D-LC the right fit?
The TFM-105-02-SM-D-LC with a 0.050 inch (1.27 mm) pitch and body dimensions of 0.375 inch length by 0.225 inch breadth is ideal for compact mezzanine boards, RF front-end modules, and sensor interface PCBs where 10 signal connections must fit within a 10 mm by 6 mm footprint. Compared to a standard 0.100 inch pitch 10-position connector occupying roughly 25 mm of board edge, the 0.050 inch pitch saves approximately 15 mm of PCB width, enabling denser circuit integration in size-constrained designs.
