Key Features
- 44-position dual-row configuration at 0.100" (2.54 mm) pitch for wide parallel bus and multi-rail power connections
- Top-mount (TM) termination style allows vertical component placement on surface mount PCBs
- Dual-height (DH) housing accommodates varied board stacking and clearance requirements
- High pin count in a single connector body reduces the number of discrete connectors needed for wide bus interfaces
Applications
The TSM-122-03-TM-DH-A-K-TR is well suited for wide parallel bus connections, multi-channel signal routing, and power distribution in embedded computing boards, industrial PLCs, and backplane interconnect systems. Its 44-position dual-row layout at 2.54 mm pitch handles high channel count interfaces such as memory buses, GPIO banks, or mixed signal and power headers in a single connector body.

Frequently Asked Questions
What is the total position count and pitch of the TSM-122-03-TM-DH-A-K-TR, and what bus widths does this support?
The TSM-122-03-TM-DH-A-K-TR provides 44 positions arranged in 2 rows at 0.100" (2.54 mm) pitch, giving 22 positions per row. This configuration supports bus widths up to 44 individual signal or power lines in one connector, making it suitable for parallel data buses such as 32-bit address plus control signals, or mixed power and signal headers common in embedded system development boards.
How does the top-mount (TM) termination style of TSM-122-03-TM-DH-A-K-TR affect PCB layout?
The top-mount (TM) termination style means the connector's solder tails land on the top surface of the PCB rather than through-hole leads passing to the bottom side. This enables the 44-position, 2.54 mm pitch terminal strip to be placed and reflowed using automated SMT processes, reducing drilling requirements and allowing routing layers beneath the connector footprint on multilayer PCBs.
When is TSM-122-03-TM-DH-A-K-TR a better choice than using two separate 22-position connectors?
A single TSM-122-03-TM-DH-A-K-TR with 44 positions is preferred over two 22-position connectors when board layout space, connector count, and mating operations need to be minimized. Using one 44-position connector at 2.54 mm pitch also reduces PCB cost by eliminating an extra connector footprint and simplifies the mating assembly step on development or production boards.
Is the dual-height (DH) housing of TSM-122-03-TM-DH-A-K-TR compatible with standard mating plugs?
The dual-height (DH) designation on the TSM-122-03-TM-DH-A-K-TR indicates a housing profile designed to mate with specific plug variants in the TSM and compatible series at 0.100" (2.54 mm) pitch. Designers should confirm that the mating plug's height profile matches the DH socket to ensure proper 44-position engagement; mismatched heights can result in incomplete electrical contact or mechanical interference in stacked board assemblies.
