he 2.5mm SMD right-angle TRRS audio jack is a compact and versatile connector designed for use in various electronic devices, particularly phones. This specific jack features four poles, making it capable of transmitting both stereo audio signals and an additional function, such as a microphone signal or remote control functionality. Its surface-mount design (SMD) allows for easy integration into circuit boards, reducing both space and assembly complexity.

As an alternative to CUI’s Same Sky audio jacks (models SJ2-25954A-SMT-TR, SJ2-25954B-SMT-TR, SJ2-25954C-SMT-TR, and SJ2-25954D-SMT-TR), this 2.5mm jack offers similar performance and reliability but may provide cost savings or different design aesthetics. The right-angle orientation of the connector facilitates a sleek, low-profile design, ideal for applications where space is limited. Overall, this 4-pole TRRS jack is a reliable and efficient choice for audio and control signal transmission in compact electronic devices
