FAQS
-
Q: What is the optimal PCB hole size and pad layout for soldering this XLR male connector?
A: The long, thin right-angle pins typically require PCB holes ranging from 1.0mm to 1.2mm in diameter, with adequate pad spacing to ensure secure soldering and prevent signal interference.
-
Q: How does the right-angle pin configuration benefit PCB-mounted audio circuits?
A: The right-angle design allows low-profile mounting, reducing strain on the solder joints and optimizing PCB real estate for compact mixer, amplifier, and audio interface designs.
-
Q: What is the maximum current and voltage rating for this PCB-mount XLR male connector?
A: Standard XLR connectors handle maximum voltages of 50V to 250V AC/DC and current ratings between 10A to 15A, depending on the pin thickness and PCB trace design.
-
Q: Is this connector suitable for high-frequency or digital audio transmission?
A: While primarily designed for analog balanced audio signals, it can support AES/EBU digital audio transmission (110Ω impedance) if PCB traces and grounding are optimized correctly.
-
Q: What considerations should be made for EMI shielding in PCB applications with this XLR connector?
A: Since this model features a plastic housing, additional ground planes, ferrite beads, or chassis grounding should be incorporated into the PCB design to minimize electromagnetic interference in professional audio applications.
