Frequently Asked Questions
What contact finish does the TFC-145-02-L-D-A use and how does it affect connection reliability?
The TFC-145-02-L-D-A uses gold (10 µin) over nickel (50 µin) on the mating contacts and tin with nickel barrier on the termination side. Gold plating ensures stable contact resistance over thousands of mating cycles, making it ideal for high-reliability board stacking in industrial and communications equipment.
How many positions does the TFC-145-02-L-D-A provide and what board-stacking heights does it support?
The TFC-145-02-L-D-A is a 45-position dual-row male connector with a body length of 4.625 inches and body breadth of 0.225 inches. It is part of SAMTEC's Tiger Eye board stacking connector family, supporting precise stack heights in compact multi-board assemblies with 90 total signal pins.
In what applications is the TFC-145-02-L-D-A Tiger Eye connector typically deployed?
This connector is used in board-to-board stacking applications across industrial control systems, data acquisition hardware, telecommunications backplanes, and embedded computing modules. Its 45-position dual-row layout handles 90 signals simultaneously, while the shrouded Tiger Eye housing protects against misalignment during assembly and field service cycles.
Is the TFC-145-02-L-D-A RoHS compliant and what material is used for its contacts?
Yes, the TFC-145-02-L-D-A is fully RoHS compliant per SAMTEC's Pbfree code. Contacts are made from phosphor bronze, a spring-grade copper alloy offering excellent elasticity and conductivity. Tin-over-nickel termination finish supports standard solder processes at peak reflow temperatures up to 260°C.
