SMT connectors are designed for high-speed automated assembly and save PCB space, while through-hole connectors provide superior mechanical retention for high-vibration environments.
Rectangular Connectors Component Intelligence
High-density interconnects for board-to-board and wire-to-board signal and power distribution.
What are Rectangular Connectors components?
Rectangular connectors are the standard for high-density signal and power routing. Selection hinges on contact pitch, mating cycle durability, current rating, and termination style (SMT, through-hole, or press-fit). Always verify mechanical keying to prevent mis-mating.
How to Choose Rectangular Connectors Components
Selecting the right rectangular connector requires balancing electrical performance with mechanical constraints.
Contact Pitch
Match the pitch to your PCB layout density; common standards range from 0.5mm to 2.54mm.
Termination Method
Choose between SMT for automated assembly, through-hole for mechanical strength, or press-fit for high-reliability backplanes.
Current & Voltage
Ensure the contact rating exceeds your peak load; consider derating curves for high-temperature environments.
Mating Cycles
Select gold-plated contacts for high-cycle applications and tin-plated for cost-sensitive, static connections.
Mechanical Keying
Use polarized housings or guide pins to prevent incorrect orientation during field installation.
