  • 10-piece pack supports multiple builds
  • 3-pin mono design fits standard 3.5mm audio circuits
  • PCB-mount format enables direct board installation
  • Compact 1.6 x 0.85 x 0.5 cm size suits tight enclosures
  • Light 11 g total weight keeps assemblies portable

10-Pack 3.5 mm Mono PCB Jacks

This pack supplies ten 3-pin 3.5 mm mono sockets designed for direct PCB mounting. They suit hobbyists, repair technicians and small-batch builders who need a compact audio connector for portable or embedded devices.

Metal-and-plastic construction runs cool

The all-passive metal-and-plastic body adds no active heat, noise or power draw to a circuit. In normal soldered use the connector simply passes the audio signal without thermal or electrical overhead.

Fits 1.6 × 0.85 cm board footprint

Each jack occupies a 1.6 × 0.85 cm area on the PCB, leaving surrounding board space free for other components. The 3.5 mm bore accepts standard mono plugs, so no special cables or adapters are required.

Questions about this item

How do I install the 3.5mm mono socket on a PCB?

Align the three pins with the board holes, insert fully, then solder each pin. The step people miss is checking pin orientation before soldering — reversing it breaks the audio path.

Will the metal contacts or plastic housing wear out first with repeated plugging?

The metal contacts lose spring tension before the plastic housing cracks, so intermittent sound usually means the jack needs replacement rather than the body.

At what current does the 3-pin connector overheat during continuous audio use?

These sockets are rated for low-level audio signals only; sustained current above a few milliamps causes the pin plating to heat up and degrade signal quality first.
