What are the key features of TFM-121-03-STL-D-RA?
- 0.050" (1.27mm) pitch dual-row layout accommodates 42 positions in a compact footprint ideal for dense PCB interconnects
- Tiger Eye contact design provides high-reliability wiping action and low insertion force for consistent electrical performance
- Right-angle through-hole orientation enables board-to-board and board-to-cable mating in space-constrained enclosures
What is TFM-121-03-STL-D-RA used for?
The TFM-121-03-STL-D-RA is used in high-density board-to-board interconnect applications where reliable signal integrity across 42 positions at 0.050" pitch is required. It suits test and measurement equipment, industrial control systems, and telecommunications hardware that demand robust mating cycles. The right-angle configuration allows edge-mounting, simplifying panel assembly and cable routing in tight enclosures.

Frequently Asked Questions
How many positions does the TFM-121-03-STL-D-RA provide and what is its contact pitch?
The TFM-121-03-STL-D-RA provides 42 positions arranged in a dual-row configuration at a 0.050" (1.27mm) pitch, enabling high-density signal routing across multiple channels in compact PCB designs.
What makes the Tiger Eye contact design reliable for repeated mating cycles?
SAMTEC Tiger Eye contacts use a wiping-action beam that displaces debris on mating, maintaining low contact resistance below 20 milliohms even after hundreds of insertion cycles, making it suitable for field-serviceable assemblies.
In which orientation is the TFM-121-03-STL-D-RA mounted on a PCB?
This connector uses a right-angle (RA) through-hole mounting orientation, allowing the mating direction to run parallel to the PCB surface, which is ideal when vertical clearance is limited inside an enclosure or chassis.
What current rating is appropriate for each pin on this terminal strip?
Each pin on the TFM series terminal strip is rated for up to 1.4A per contact at 0.050" pitch, making the connector suitable for mixed signal and low-power supply distribution across all 42 positions.
