3.5mm (1/8″) for consumer audio, laptops, smartphones, gaming headsets, and multimedia devices. 2.5mm (3/32″) sub‑miniature size for compact wearables, portable communication radios, embedded modules, and space‑constrained portable electronics where board real estate is at a premium.
TRS (3‑conductor) configuration for standard stereo audio (left / right / ground) – ideal for headphones, speakers, and line‑out applications. TRRS (4‑conductor) adds a microphone channel plus remote control button support (play/pause/volume), compatible with both CTIA and OMTP wiring standards for universal smartphone headset compatibility.
SMT (tape‑and‑reel) for automated pick‑and‑place assembly. DIP Through‑Hole for maximum mechanical retention and wave soldering. Right‑Angle (90°) for edge‑mount PCB designs. Mid‑Mount (recessed) for ultra‑thin devices reducing height above board. All termination styles support automated and manual assembly processes.
Phosphor bronze contacts with standard gold plating deliver contact resistance ≤ 50mΩ initial, ensuring clean signal transmission and long‑term reliability. Gold plating provides superior corrosion protection against oxidation, maintaining signal integrity in humid or challenging environments.
Internal switch contacts (normally closed) actuated by plug insertion enable automatic speaker disconnect when headphones are plugged in, accessory detection, mode selection, and remote button‑press sensing. As documented in CUI Devices‘ audio jack technical guide, switched configurations allow designers to implement intelligent accessory interfaces without additional ICs.
All Vistar phone jack connectors are manufactured under ISO 9001:2015 and fully comply with RoHS 3 (EU Directive 2015/863) and REACH SVHC regulations. Dimensional and performance characteristics align with IEC 60603‑11 for LF concentric audio connectors – suitable for export to EU, North America, and all regulated global markets.

Shenzhen Vistar Electronics Co., Ltd. is a professional phone jack manufacturer based in Pingshan District, Shenzhen, China – the global electronics manufacturing hub. Since 2009, we have specialized in the design, manufacturing, and global supply of audio interconnect solutions, including phone jack connectors, audio jack connectors, DC power jacks, USB connectors, and electromechanical switches for OEM and ODM customers in 50+ countries.
Our phone jack connector portfolio covers both 3.5mm (1/8″) mini‑plug and 2.5mm (3/32″) sub‑miniature sizes, available in TRS (3‑conductor stereo) and TRRS (4‑conductor stereo + microphone + remote control) configurations. Termination styles include SMT (tape‑and‑reel for automated pick‑and‑place), DIP Through‑Hole, Right‑Angle (90°), and Mid‑Mount (recessed) for ultra‑thin device integration. All models feature gold‑plated phosphor bronze contacts (contact resistance ≤ 50mΩ) and are rated 1A at 12VDC with 5,000 mating cycles minimum.
All Vistar phone jack connectors are manufactured under an ISO 9001:2015 certified quality management system, fully compliant with RoHS 3 (EU Directive 2015/863) and REACH SVHC environmental regulations. Dimensional and performance characteristics align with IEC 60603‑11 for concentric connectors used in low‑frequency (LF) audio applications such as the interconnection of headphones and microphones in sound system components.
For authoritative technical background, we recommend consulting the CUI Devices audio jack technical library (available through DigiKey) for detailed documentation on 2.5mm and 3.5mm audio jacks across multiple mounting styles and internal switch configurations, as well as the CECA (China Electronic Components Association) technical guide on 3.5mm plug connectors for PCB layout design considerations, ESD protection strategies, and grounding best practices for audio interface circuits. These resources validate Vistar‘s alignment with internationally recognized audio interconnect specifications and reliability standards.
