Key Features
- High-reliability Tiger Eye contact design engineered for thousands of mating cycles with consistent low contact resistance across dual-row configurations
- Ultra-fine 0.050" (1.27 mm) pitch enables high pin-count connectivity with 40 pins in a minimal PCB footprint
- Dual-row surface mount (SM) configuration provides twice the contact density versus single-row alternatives at equivalent board length
- LC low-contact-force design reduces mating and unmating forces while maintaining reliable electrical connections in demanding environments
Applications
The TFM-120-03-SM-D-LC Tiger Eye terminal strip is used in high-reliability board-to-board and mezzanine interconnect applications in aerospace, defense, and high-end computing systems requiring 0.050" pitch density. Its precision contacts and dual-row SMT design make it suitable for data acquisition equipment, test and measurement modules, and military electronics where long cycle life and signal integrity are critical. The surface mount format also supports automated PCB assembly in both high-reliability and high-volume production environments.

Frequently Asked Questions
What pitch and pin count does the TFM-120-03-SM-D-LC provide in its dual-row configuration?
The TFM-120-03-SM-D-LC uses a 0.050" pitch in a dual-row surface mount layout providing 40 pins total across 2 rows. This ultra-fine pitch allows approximately twice the contact count per inch compared to standard 0.100" pitch connectors, making it ideal for space-constrained high-density PCB interconnect applications.
Which high-reliability applications benefit most from the Tiger Eye contact design in TFM-120-03-SM-D-LC?
The Tiger Eye contact design withstands thousands of mating cycles while supporting more than 20 signal channels per linear inch of PCB edge, making it ideal for aerospace, defense avionics, and military electronics. Its reliable performance under repeated mating and harsh environmental conditions suits high-bandwidth data acquisition and instrumentation systems demanding long service life.
When should a designer choose TFM-120-03-SM-D-LC over a standard 0.100" pitch connector?
The TFM-120-03-SM-D-LC is the preferred choice when PCB space is limited but a high pin count is needed, offering 40 pins in a dual-row SMT footprint much smaller than equivalent 0.100" pitch connectors. It excels in FPGA interface boards, high-speed data buses, and compact test equipment where dense signal routing must fit within tight board dimensions.
