Frequently Asked Questions
How many positions and what pitch does the TSM-122-03-FM-DH-A-K-TR provide?
The TSM-122-03-FM-DH-A-K-TR features 44 positions arranged in a dual-row configuration on a 2.54 mm (0.100 inch) pitch. Each contact is rated for up to 3 A current, making it suitable for mixed signal and moderate power distribution applications.
What does the K option (friction-lock keying) mean for the TSM-122-03-FM-DH-A-K-TR?
The K suffix indicates a friction-lock keying feature that physically prevents incorrect mating with non-keyed or differently-keyed mating connectors. This reduces mis-mating risk during assembly and field service, improving reliability in rack systems and modular embedded boards with multiple 44-pin connectors.
Is TSM-122-03-FM-DH-A-K-TR available in tape-and-reel for automated assembly?
Yes, the TR suffix confirms tape-and-reel packaging for the TSM-122-03-FM-DH-A-K-TR. This format is compatible with standard SMT pick-and-place equipment and supports high-volume reflow soldering at peak temperatures up to 260°C per IPC/JEDEC J-STD-020.
What is a suitable mating connector family for TSM-122-03-FM-DH-A-K-TR?
SAMTEC's TSW and SSW series headers on 2.54 mm pitch are typical mating options for TSM series terminal strips. The dual-row 22-position-per-row layout of the TSM-122 mates with corresponding 44-pin headers, enabling reliable board-stacking at contact separations from 8.5 mm to over 20 mm depending on the selected mating part.
