Frequently Asked Questions
What does the STL suffix indicate on TSM-125-03-STL-DH-A-P-TR, and how does it affect solder joint quality?
STL stands for standard-length tails, meaning the SMT pads extend a controlled distance below the connector body for consistent solder fillet formation across all 50 positions at 2.54 mm pitch. Compared to shorter tails, standard-length tails provide a larger solder wetted area and stronger mechanical pull-out resistance, reducing the risk of joint fracture in vibration-exposed industrial PCB assemblies.
How does the 50-position dual-row configuration of TSM-125-03-STL-DH-A-P-TR support high-speed digital backplane routing?
With 50 positions across 2 rows at .100" (2.54 mm) pitch, TSM-125-03-STL-DH-A-P-TR provides 100 signal paths in a compact SMT footprint. This density enables simultaneous routing of data buses, control signals, and power rails from a single connector interface, reducing the number of connector sites on digital backplanes and embedded computing boards operating in industrial environments.
For a production line running tape-and-reel SMT connectors, how does TSM-125-03-STL-DH-A-P-TR reduce placement errors compared to loose-packaged parts?
Tape-and-reel packaging on TSM-125-03-STL-DH-A-P-TR ensures each 50-position connector is precisely oriented in the carrier tape, allowing SMT pick-and-place machines to place parts consistently at 2.54 mm pitch without manual handling. This eliminates the 180-degree rotation errors common with loose-packaged connectors and supports throughput rates exceeding several thousand placements per hour in high-volume assembly lines.
