What are the key features of SFM-145-T2-ZZ-D-A-K-TR?
- 90-position dual-row (2x45) socket strip with 0.050" (1.27 mm) pitch providing maximum contact density for complex board-to-board signal interfaces
- Tape-and-reel (TR) packaging enabling continuous automated pick-and-place placement on 1.27 mm pitch SMT pads in high-volume PCB production
- High reliability SAMTEC SFM series design with gold-plated contacts rated for repeated mating cycles in demanding aerospace, defense, and industrial applications
What is SFM-145-T2-ZZ-D-A-K-TR used for?
The SFM-145-T2-ZZ-D-A-K-TR is used in high-density FPGA mezzanine boards, processor carrier cards, and complex embedded computing systems where 90 signals must be simultaneously routed between stacked PCBs at 0.050" pitch. Its surface mount design and tape-and-reel packaging make it a production-ready choice for automated assembly of telecommunications switching modules and high-speed data acquisition systems. Defense avionics and radar signal processing designers rely on this socket strip for its high contact count and reliability in environments requiring operation from -55°C to +125°C.

Frequently Asked Questions
How many contacts does SFM-145-T2-ZZ-D-A-K-TR provide, and what pitch spacing enables its high-density layout?
The SFM-145-T2-ZZ-D-A-K-TR provides 90 contacts in a dual-row (2x45) configuration with 0.050" (1.27 mm) pitch. This high contact density allows 90 individual signal or power lines to be routed across a board-to-board interface in less than 58 mm of connector length, making it critical for FPGA expansion modules, high-speed processor interfaces, and multi-channel data acquisition systems.
Which design requirements make SFM-145-T2-ZZ-D-A-K-TR more suitable than a lower pin count connector for a DSP board interface?
DSP boards running parallel buses, multi-channel ADC interfaces, or FPGA I/O banks often require 64 to 100 connections between main boards and mezzanine modules. The SFM-145-T2-ZZ-D-A-K-TR fills a 90-contact requirement with a single 0.050" pitch connector rather than combining multiple lower-count connectors, reducing PCB assembly complexity, minimizing impedance mismatches across the interface, and maintaining signal integrity at bus frequencies above 200 MHz.
What procurement advantages does the tape-and-reel format of SFM-145-T2-ZZ-D-A-K-TR offer for contract manufacturers?
Tape-and-reel packaging for the SFM-145-T2-ZZ-D-A-K-TR allows contract electronics manufacturers to place this 90-position 0.050" pitch socket strip directly from automated pick-and-place feeders, typically at 500 to 1,000 units per reel. This eliminates manual tube or tray handling that increases placement cycle time and operator error rates on fine-pitch SMT components, resulting in lower assembly cost per board in high-volume runs of telecommunications, industrial automation, and defense electronics products.
