What are the key features of TFM-146-04-L-D-LC?
- 46-position dual-row Tiger Eye contact strip on .050" (1.27 mm) pitch providing 92 total signal connections in an ultra-compact surface mount footprint
- Low-clearance (LC) SMT termination enabling minimal board-to-board stack height for thin form-factor and mezzanine card designs
- High-reliability Tiger Eye contact geometry delivering controlled normal force for consistent electrical performance across temperatures from -55°C to 125°C
What is TFM-146-04-L-D-LC used for?
The TFM-146-04-L-D-LC is optimized for high-density mezzanine and stacking applications in FPGA development boards, high-speed data acquisition systems, and compact industrial controllers. With 92 contacts on a .050" pitch, it enables dense signal routing between stacked PCBs with a board separation as low as 4 mm. Its surface mount design is compatible with automated SMT reflow assembly and supports mixed signal, power, and ground routing in a single connector.

Frequently Asked Questions
How many total contacts does the TFM-146-04-L-D-LC provide and at what pitch?
The TFM-146-04-L-D-LC provides 92 total contacts arranged in 2 rows of 46 positions each, all on a .050" (1.27 mm) pitch. This high contact density allows designers to route 92 signals or mixed signal and power lines between PCBs in a connector body less than 60 mm in total length.
Which mezzanine or stacking scenarios make the TFM-146-04-L-D-LC the preferred choice over wider-pitch alternatives?
The TFM-146-04-L-D-LC is the preferred choice when a design must accommodate 92 or more connections between two parallel boards with a stack height under 6 mm. At .050" pitch, it occupies roughly half the board area of a .100" pitch connector with the same signal count, making it ideal for high-layer-count PCBs where routing density is critical.
What is the operating temperature range of the TFM-146-04-L-D-LC and how does that affect material selection for nearby components?
The TFM-146-04-L-D-LC is rated for operation from -55°C to 125°C, which means nearby passive and active components must also tolerate this extended industrial temperature range. Designers should verify that adjacent decoupling capacitors, resistors, and ICs are specified for at least -40°C to 125°C to avoid creating a thermal weak point in the assembly.
