Key Features
- 90 dual-row positions at 0.050" (1.27 mm) pitch for maximum connection density in a single connector
- Tiger Eye contact design for low insertion force and reliable signal integrity over extended mating cycles
- Standard FM-height through-hole mounting compatible with common PCB assembly workflows
- No keying (open A designation) allowing flexible orientation in symmetric board layouts
Applications
The TFC-145-02-FM-D-A is used in applications requiring extremely high pin counts in a compact 1.27 mm pitch footprint, such as FPGA mezzanine cards, high-speed data acquisition boards, and multi-axis servo drive controllers. With 90 positions across dual rows, it enables comprehensive I/O and power distribution in a single connector. The absence of a polarizing key suits symmetric interface designs where orientation is managed by the PCB layout itself.

Frequently Asked Questions
What is the maximum pin count and pitch of the SAMTEC TFC-145-02-FM-D-A terminal strip?
The TFC-145-02-FM-D-A provides 90 total positions in a dual-row configuration, with 45 pins per row and a 0.050-inch (1.27 mm) pitch, making it among the highest-density connectors in the SAMTEC TFC series and suited for applications requiring extensive simultaneous signal routing in a minimal PCB footprint.
How does the absence of a polarizing key (A designation) affect system design with this connector?
The A (no-key) designation means the TFC-145-02-FM-D-A has no polarizing slot, requiring the PCB layout to enforce correct mating orientation through mechanical alignment features or silkscreen markings. This increases layout flexibility for symmetric 90-position interfaces but demands careful design attention to prevent reverse insertion in field-assembly environments.
What procurement benefits does the SAMTEC TFC-145-02-FM-D-A offer for high-volume production?
The TFC-145-02-FM-D-A is part of SAMTEC's Cost-Effective TFC series, which uses a standard 1.27 mm pitch and 90-position dual-row format supported by a broad distributor network with global stock, enabling volume buyers to maintain short lead times and consistent pricing across production runs without single-source risk.
