Key Features
- 10-position dual-row Tiger Eye contact design on 0.050" (1.27 mm) pitch for high-density SMT signal interconnects
- Split board lock mounting option ensures mechanical retention with forces typically exceeding 5 N, preventing connector movement under vibration
- Matte tin over nickel contact finish (50 µin minimum) balances cost and solderability for low-current signal applications
Applications
The TFM-105-02-S-D-LC is used in compact embedded systems, portable instruments, and medical devices where high-density 0.050-inch pitch connections are required. The vertical surface mount orientation suits space-constrained PCB designs needing reliable board-to-board or wire-to-board signal routing. The Tiger Eye contact geometry and split board lock provide secure, low-insertion-force mating suitable for frequent connect-disconnect cycles.

Frequently Asked Questions
What contact finish does the TFM-105-02-S-D-LC use, and how does it affect soldering?
The TFM-105-02-S-D-LC uses matte tin over nickel plating with a minimum 50 micro-inch tin thickness. This finish is compatible with standard SAC305 lead-free reflow solder profiles at peak temperatures up to 260°C, providing reliable solder joints without gold embrittlement issues seen with some alternative contact finishes.
How does the split board lock improve mechanical reliability on the TFM-105-02-S-D-LC?
The split board lock feature provides mechanical retention to the PCB by engaging through-board apertures with a holding force typically above 5 N. This prevents the 10-position connector from shifting during assembly reflow and resists vibration-induced contact fretting in applications like mobile industrial equipment or ruggedized instruments.
For which compact signal routing applications is the TFM-105-02-S-D-LC a strong fit?
This 10-position, 0.050-inch pitch Tiger Eye connector is well-suited for embedded microcontroller expansion headers, portable medical diagnostics, and FPGA evaluation boards where board space is limited. Each contact is rated for low-current signals up to approximately 1 A, making it appropriate for logic-level interfaces such as UART, SPI, or I2C at voltages up to 5 V.
How does the body dimension of TFM-105-02-S-D-LC constrain PCB keep-out area?
The connector body measures 0.375 inches in length, 0.225 inches in breadth, and 0.225 inches in depth. These dimensions correspond to a PCB footprint of approximately 9.5 mm × 5.7 mm, allowing designers to fit the 10-position dual-row connector within the keep-out zones typical for 0.050-inch pitch component grids on dense multilayer boards.
