Frequently Asked Questions
What mounting method does the B5741-220-F-T-0 use, and how does it improve board retention?
The B5741-220-F-T-0 uses through-hole solder mounting with dedicated solder holding posts for enhanced mechanical retention. The solder posts add anchor points beyond the signal contacts, increasing pull-out strength by typically 2 to 5 times compared to contact-only through-hole connectors, which is essential in vibration-prone industrial environments.
What are the body dimensions of the B5741-220-F-T-0, and how do they affect PCB layout planning?
The B5741-220-F-T-0 has a body length of 0.911 inch (23.1 mm), breadth of 0.215 inch (5.5 mm), and depth of 0.202 inch (5.1 mm). These dimensions define the PCB keep-out zone and component placement clearance requirements, and must be factored into PCB layout to ensure adequate spacing from adjacent components and mating connector clearance.
Which soldering processes are compatible with the B5741-220-F-T-0 board socket connector?
The B5741-220-F-T-0 supports through-hole wave soldering and selective soldering processes. Its Sn/Pb (tin-lead) contact finish on termination pins is optimized for eutectic solder at 183°C melting point. Wave soldering preheat temperatures of 100 to 130°C followed by a wave temperature of 250 to 260°C are typical for reliable joint formation.
For which connector mating applications is the B5741-220-F-T-0 socket shell style best suited?
The B5741-220-F-T-0 socket shell style is designed for board-to-board and wire-to-board mating applications, accepting corresponding male header pins. It is well-suited for modular daughtercard connections, instrument front-panel I/O, and embedded control module sockets where 20 or more mating cycles over the product lifetime are expected.
