Frequently Asked Questions
What does the FM designation mean in TSM-114-03-FM-DH-A-K-TR and how does it affect mating compatibility?
The FM designation in TSM-114-03-FM-DH-A-K-TR indicates a female mating style, meaning the connector accepts male pin headers or terminal pins. This makes it compatible with standard 0.100 inch pitch male headers commonly used on microcontroller boards, development kits, and backplane connectors, supporting 28-pin dual-row board-to-board or wire-to-board connections with straightforward plug-in assembly.
How many signal positions does the TSM-114-03-FM-DH-A-K-TR provide in its dual-row configuration?
The TSM-114-03-FM-DH-A-K-TR provides 28 positions total in a dual-row DH layout with 14 contacts per row at 0.100 inch (2.54 mm) pitch. This configuration supports 28 individual signal or power connections, making it suitable for parallel data bus interfaces, GPIO expansion headers, and mixed signal-plus-power connectors in embedded system designs.
For what PCB manufacturing processes is the TSM-114-03-FM-DH-A-K-TR designed?
The TSM-114-03-FM-DH-A-K-TR is designed for surface mount reflow soldering and ships in tape-and-reel (TR) packaging compatible with automated pick-and-place equipment. The SMD termination eliminates the need for through-hole PCB drilling, reducing board fabrication time and cost. The 0.100 inch pitch is within standard SMD handling tolerances for high-volume production environments.
When would a designer choose TSM-114-03-FM-DH-A-K-TR over a through-hole terminal strip of similar pitch?
A designer would choose the TSM-114-03-FM-DH-A-K-TR over a through-hole alternative when the PCB design requires all components on one side using reflow soldering, eliminating the need for a separate wave soldering or hand-soldering step. The surface mount version also enables denser component placement since no through-hole barrels occupy PCB layers, which is important in 4-layer or 6-layer boards with tight routing constraints at 0.100 inch pitch.
