Frequently Asked Questions
Q: What does TRRS mean, and how many contacts does this 3.5mm audio jack have?
A: TRRS stands for Tip-Ring-Ring-Sleeve, which refers to the 4-pole configuration of this connector. It has 4 contacts that carry stereo audio (left and right channels), a microphone signal, and a ground — allowing both headphone output and microphone input through a single 3.5mm jack.
Q: Is this a through-hole or surface-mount (SMD) component?
A: This is a through-hole (DIP) component with a right-angle (horizontal) orientation, designed to be soldered directly through a PCB. It is not a surface-mount device.
Q: Does this audio jack connector have an internal switch?
A: No, this connector does not include an internal switch. It is a straightforward 4-pole TRRS socket without switching contacts, making it suitable for applications where switch detection is not required.
Q: What is the rated voltage for these PCB audio jack connectors?
A: These connectors are rated at 30V, which is suitable for standard audio signal applications in DIY electronics, prototyping, and device repair projects.
