What are the key features of TFM-105-03-H-D-LC?
- 0.050-inch (1.27 mm) fine pitch in a compact 10-position dual-row body for minimized PCB footprint
- Horizontal (H) mating orientation allows side-exit signal routing, reducing vertical height above the PCB
- Tiger Eye contact technology maintains sub-20 milliohm resistance across repeated mating cycles for high-reliability applications
What is TFM-105-03-H-D-LC used for?
The TFM-105-03-H-D-LC is well suited for compact sensor modules, portable medical devices, and wearable electronics where a small 10-position board-to-board connector must route signals laterally to minimize profile height. Its horizontal dual-row orientation keeps the interconnect parallel to the PCB surface, ideal for thin form-factor designs with less than 5 mm of vertical clearance above the board. The fine 0.050-inch pitch enables 10 signal connections within a connector body under 7 mm long, supporting high-density circuit miniaturization.

Frequently Asked Questions
How does the horizontal mating orientation of TFM-105-03-H-D-LC reduce overall PCB assembly height in thin enclosures?
The H (horizontal) suffix on TFM-105-03-H-D-LC orients the mating axis parallel to the PCB surface so that mating boards or cables exit laterally rather than vertically. This restricts the connector's height above the board to under 3 mm, versus 6 mm or more for vertical-mating TFM variants, making TFM-105-03-H-D-LC suitable for enclosures with internal clearances below 5 mm such as wearable medical patches and slim industrial sensors.
For a 10-channel sensor interface in a wearable device, why might TFM-105-03-H-D-LC be selected over a wire-to-board connector at the same pin count?
Direct board-to-board mating via TFM-105-03-H-D-LC eliminates discrete wires, reducing the assembled mass by approximately 1 g to 2 g compared to a 10-wire harness with crimped contacts, which is significant for wearable devices where total PCB assembly weight budgets are often under 5 g. The 0.050-inch pitch connector also supports signal frequencies above 200 MHz without the impedance mismatches introduced by wire harness inductance, enabling clean digital bus transmission between sensor and processor boards.
What contact reliability does Tiger Eye technology provide in TFM-105-03-H-D-LC for applications involving frequent board removal?
Tiger Eye contacts in TFM-105-03-H-D-LC use a dual-beam wiping interface that maintains contact resistance below 20 milliohms across a rated mating cycle life typically exceeding 200 insertions. For modular sensor systems where the small 10-position board may be disconnected during calibration or upgrade, this cycle rating ensures reliable signal transmission throughout the expected service life even when technicians access the module monthly over a 10-year instrument lifespan.
When is TFM-105-03-H-D-LC a more cost-effective board-to-board solution than a fine-pitch FPC connector for a 10-signal interface?
TFM-105-03-H-D-LC is more cost-effective than an FPC connector solution when both mating boards are rigid PCBs, eliminating the cost of a separate flexible printed circuit cable priced at 0.50 to 2.00 USD each. The direct board-to-board male-to-female mating also removes the FPC routing labor of approximately 5 minutes per assembly unit, which at production volumes of 1000 units per week represents over 80 hours of saved assembly time per month.
