What are the key features of TSM-125-04-FM-DH-A-K-TR?
- 50 positions in dual-row .100" (2.54 mm) pitch for broad connectivity on a standard SMT footprint
- Female (FM) contact gender accepts standard 2.54 mm dual-row male headers for secure board-to-board mating
- Gold-plated contacts on phosphor bronze ensure minimal contact resistance and reliable performance over many mating cycles
- Tape-and-reel (TR) packaging and -K keying feature simplify automated assembly and prevent mis-mating
What is TSM-125-04-FM-DH-A-K-TR used for?
The TSM-125-04-FM-DH-A-K-TR is used in backplane-to-daughtercard interfaces, industrial I/O expansion boards, and FPGA carrier cards where 50 dual-row SMT signal and power connections are needed in a standard 2.54 mm pitch footprint. Its keyed female contacts prevent incorrect insertion in field-replaceable module systems such as VME, cPCI, or custom embedded computing platforms. The tape-and-reel format supports high-volume automated PCB production in communications and defense electronics.

Frequently Asked Questions
How much current can each TSM-125-04-FM-DH-A-K-TR contact carry?
The connector is listed for 3 A per contact, subject to contact count, conductor size, temperature rise, and the manufacturer derating guidance.
Can this terminal strip operate across industrial temperatures?
The stated range is -65°C to 150°C, but application qualification should also consider PCB material, solder joints, mating cycles, and environmental exposure.
For automated assembly, what configuration details require verification?
The dual-row strip provides 50 pins on a 2.54 mm pitch with tape-and-reel packaging, so footprint, orientation, and reel setup should be confirmed.
