Frequently Asked Questions
What mechanical benefit do the weld tabs provide on TFM-120-01-L-D-WT compared to versions without this feature?
The weld tabs (WT) on the TFM-120-01-L-D-WT are soldered additional anchor points that reinforce the connector's mechanical bond to the PCB, significantly increasing resistance to board pull-off forces beyond those handled by the 40 signal contact pads alone. In vibration-intensive environments rated at 10 G or higher, these tabs prevent connector lift-off during sustained mechanical stress, a critical advantage for industrial, automotive, and telecom rack-mount applications.
How does the 15 micro-inch gold over 50 micro-inch nickel contact finish on TFM-120-01-L-D-WT compare to thinner gold alternatives?
The 15 micro-inch gold plating over 50 micro-inch nickel barrier on TFM-120-01-L-D-WT provides substantially greater wear resistance than 3 micro-inch gold alternatives, supporting 500 or more mating cycles while maintaining contact resistance below 20 milliohms. The thick nickel barrier layer also prevents gold diffusion and substrate corrosion, extending reliable service life across operating temperatures from -55°C to +125°C in high-reliability applications.
For a telecom blade server design requiring 40-pin board stacking with RoHS compliance, how suitable is TFM-120-01-L-D-WT?
The TFM-120-01-L-D-WT is highly suitable for RoHS-compliant telecom blade designs because it uses lead-free tin over nickel termination finish compatible with standard lead-free reflow soldering at up to 260°C. The 40-pin dual-row configuration at 0.050 inch pitch delivers sufficient signal density for telecom line card interfaces, while the weld tabs and rated YTEOL of 9.15 years support the long service life expected in carrier-grade equipment.
What body dimensions should PCB layout engineers use when planning footprints for TFM-120-01-L-D-WT?
The TFM-120-01-L-D-WT body measures 1.263 inches in length, 0.225 inch in breadth, and 0.220 inch in depth, defining the keep-out zone and copper land pattern area on the PCB. Layout engineers should add clearance margins of at least 0.5 mm on all sides of these body dimensions to accommodate solder paste coverage and weld tab pads without violating design rule check constraints on adjacent components.
