Product Description: 3.5 mm SMT Right-Angle Audio Jack (TRS, 3 Poles, with Tip Switch)
This component is a compact, surface-mount (SMT) 3.5 mm audio jack, engineered for right-angle placement on printed circuit boards. It is ideal for space-constrained applications such as portable media players, laptops, communication equipment, and consumer audio devices where low-profile, horizontal insertion is required.
The jack features a 3-pole TRS (Tip-Ring-Sleeve) configuration, supporting standard unbalanced stereo audio signals plus a common ground. A critical functional element is the integrated Tip switch (normally closed). This switch detects plug insertion by opening the circuit at the tip contact, enabling functions like automatic speaker muting or signal routing detection.
Constructed for durability and performance, the housing uses high-temperature PPA (Polyphthalamide) insulation material, providing excellent mechanical strength, thermal resistance for SMT reflow soldering, and reliable electrical isolation. The contact system is fabricated from bronze, chosen for its superior spring properties, corrosion resistance, and low contact resistance. Electrical ratings are DC 12V, 1A, making it suitable for low-power switching and signal lines.
The jack is rated for a minimum of 5,000 cycles of plug insertion and extraction, ensuring reliable operation over the expected lifespan of most portable devices. Its robust bronze contacts and PPA housing guarantee consistent contact force and signal integrity throughout this cycle life.
