Frequently Asked Questions
How many positions does the TFM-125-02-S-D connector have and what is its pitch?
The TFM-125-02-S-D is a 50-position (25 per row) dual-row connector with a 2 mm pitch. Its body measures 1.375 inches in length and 0.225 inches in breadth, making it suitable for high-density board stacking applications.
What contact finish does the TFM-125-02-S-D use and why does it matter for reliability?
The TFM-125-02-S-D uses Tin (Sn) plating over a Nickel (Ni) barrier on the termination contacts. This 2-layer finish provides corrosion resistance and reliable electrical contact, ensuring consistent performance across the connector's rated lifecycle in industrial and commercial applications.
In which stacking PCB designs can the TFM-125-02-S-D be used instead of higher-pitch alternatives?
The TFM-125-02-S-D's 2 mm pitch and 50-pin dual-row configuration make it a compact alternative to 2.54 mm pitch connectors in space-critical designs. It suits embedded modules, modular telecom cards, and test equipment motherboards where a smaller footprint is needed without sacrificing pin count.
Is the TFM-125-02-S-D RoHS compliant and suitable for environmentally regulated markets?
Yes, the TFM-125-02-S-D is fully RoHS compliant, meaning it is free of restricted hazardous substances such as lead. This makes it suitable for deployment in Europe and other markets with strict environmental regulations, supporting compliance with EU Directive 2011/65/EU across industrial and commercial product lines.
