What are the key features of TFM-146-04-SM-D-LC?
- 46-position dual-row surface-mount layout at 0.050" (1.27 mm) pitch provides 92 signal contacts in a minimal PCB footprint
- Tiger Eye contact technology ensures reliable wiping action and consistent contact normal force across the full 92-contact interface
- Low-clearance (LC) body minimizes the connector height above the PCB, enabling tight board-to-board spacing in mezzanine stack configurations
What is TFM-146-04-SM-D-LC used for?
The TFM-146-04-SM-D-LC is designed for high-density mezzanine and board-to-board interconnect in networking line cards, telecommunications base-station modules, and industrial control backplanes. The 92-contact surface-mount configuration is compatible with automated SMT assembly, reducing board population costs at volume. Its low-clearance profile makes it a strong candidate for compact multi-board stack designs where strict mechanical height budgets must be maintained.

Frequently Asked Questions
What is the total contact count of TFM-146-04-SM-D-LC and how are the contacts arranged?
The TFM-146-04-SM-D-LC has 92 contacts arranged in a dual-row configuration with 46 positions per row at 0.050" (1.27 mm) pitch. This high contact density allows engineers to route a large number of high-speed digital signals through a compact PCB footprint compared to equivalent 0.100" pitch connectors.
How does the surface-mount termination on TFM-146-04-SM-D-LC benefit high-volume PCB assembly?
Surface-mount (SM) termination allows the TFM-146-04-SM-D-LC to be placed and reflowed in a single SMT pass alongside other PCB components, eliminating the need for secondary through-hole soldering operations. This reduces assembly cycle time and cost in high-volume production, and the fine 0.050" pitch footprint is compatible with standard 0201 to 0603 component placement equipment.
When should a designer choose TFM-146-04-SM-D-LC over a larger-pitch 0.100" connector for a 92-signal interface?
When PCB area and board-to-board stack height are primary constraints, the TFM-146-04-SM-D-LC at 0.050" pitch occupies roughly half the PCB footprint of a 92-contact 0.100" pitch connector. The low-clearance body further reduces the mezzanine stack height compared to standard-height connectors, enabling total assembly heights below 5 mm in compact multi-board modules.
