Frequently Asked Questions
How many positions and what pitch does the TFM-144-11-S-D provide?
The TFM-144-11-S-D features 144 total positions arranged in a dual-row layout with a 0.050" (1.27 mm) pitch, making it one of the highest-density Tiger Eye terminal strips available from SAMTEC for compact PCB designs.
What current rating does each pin of the TFM-144-11-S-D support?
Each contact in the TFM-144-11-S-D is rated for approximately 1 A continuous current at room temperature. With 144 pins in the connector, aggregate current capacity can be distributed across multiple pins for power rails in addition to signal lines.
Which board-level applications benefit most from using the TFM-144-11-S-D instead of wider-pitch alternatives?
Applications requiring very high signal density in limited PCB area benefit most, including 10G Ethernet line cards, FPGA mezzanine modules, and SSD controller boards. The 1.27 mm pitch saves up to 40% board space compared to 2.00 mm pitch connectors while maintaining reliable contact force across -55°C to +125°C temperature range.
What is the mating cycle life of the TFM-144-11-S-D Tiger Eye contacts?
SAMTEC Tiger Eye contacts in the TFM series are rated for a minimum of 1000 mating cycles. The beryllium copper alloy contacts maintain controlled 30 g normal force per pin after repeated insertions, ensuring consistent contact resistance below 20 mΩ throughout the rated life.
