Frequently Asked Questions
What contact finish does the TFM-140-22-L-D use and why does it matter for high-cycle applications?
The TFM-140-22-L-D uses 15 microinch gold over 50 microinch nickel on the mating contacts, which provides very low and stable contact resistance over many insertion and extraction cycles. Gold plating at 15 microinch is the industry-standard minimum for connectors expected to withstand repeated mating in test fixtures and hot-swap mezzanine card slots.
How many positions and at what pitch does the TFM-140-22-L-D support for dense signal routing?
The TFM-140-22-L-D provides 80 positions in a dual-row configuration at 0.050 inch (1.27 mm) pitch across a 2.125 inch body length. This high density makes it a practical choice for routing 64-bit buses plus control signals in a single connector without the larger board footprint required by 0.100 inch pitch alternatives.
How does the Tiger Eye contact design in the TFM-140-22-L-D reduce insertion force compared to standard pin headers?
The Tiger Eye contact geometry features a multi-beam spring structure that distributes the normal force across 2 or more contact points per pin while maintaining low insertion force per contact. For an 80-position connector, this means the total mating force stays manageable even with all 80 pins engaging simultaneously, reducing the risk of PCB flexure damage during connector installation and removal in production environments.
