Frequently Asked Questions
How many positions does TSM-129-03-TM-DH-A-P-TR provide, and how are they distributed across rows?
TSM-129-03-TM-DH-A-P-TR provides 58 positions arranged in a triple-row (-03) layout at 0.100" (2.54 mm) pitch. The three-row configuration allows engineers to allocate separate rows for power, ground, and signal functions, reducing crosstalk and simplifying PCB routing compared to a single wide-row connector.
What advantage does the polarized (-P) keying provide in high-volume board assembly?
The polarized -P keying feature adds a mechanical asymmetry to the TSM-129-03-TM-DH-A-P-TR housing that physically prevents incorrect insertion orientation during SMT placement or manual rework. In triple-row 58-pin connectors where misorientation could damage all 58 contacts or reverse power supplies, polarization eliminates assembly errors without requiring additional inspection steps.
How does the dual-height standoff in TSM-129-03-TM-DH-A-P-TR affect board-to-board clearance planning?
The dual-height (-DH) standoff elevates the connector body above the PCB surface, creating a defined gap between the host board and any mating board or module. Engineers must verify that the standoff height plus the mated connector depth accommodates all surface-mounted components on the inner-facing sides of both boards, typically requiring a clearance budget of at least 3 mm to 5 mm depending on the tallest nearby components.
For which embedded computing form factors is a 58-position 0.100" triple-row SMT strip the right connector choice?
A 58-pin triple-row 0.100" pitch strip is well-matched to PC/104 expansion bus derivatives, custom SBC edge connectors, and industrial I/O modules where 50 to 64 pins are needed at standard 2.54 mm pitch. The SMT termination style of TSM-129-03-TM-DH-A-P-TR suits modern PCBs that have moved away from through-hole, while the 0.100" pitch allows higher current per pin than finer-pitch alternatives.
