Unique-Bargains Microphone Cartridge 8 Pcs 2.6mm Wire Electret Condenser Pick-up 4mm x 2mm

SKU CH-QFZP-16QPB

Eight electret condenser microphone cartridges with 2.6 mm wire leads for voice control circuits

  • 8-piece pack supplies multiple microphone cartridges for projects
  • 6mm wire length enables compact circuit integration
  • Electret condenser design captures voice in recorder and control circuits
  • Metal external material protects the capsule in cassette and wireless devices
  • Red and black colour coding simplifies polarity identification during assembly

Eight-piece electret condenser cartridge set

This pack contains eight electret condenser microphone cartridges designed for audio pickup in compact devices. Each unit features a 2.6mm wire lead and a metal housing measuring 4mm by 2mm. The components arrive new and are intended for integration into recording or voice-control circuits.

Consistent sensitivity in voice-control circuits

The electret element maintains stable output during extended recording sessions such as dictation or telemetry logging. Metal shielding around the capsule reduces handling noise when the host device is moved. Performance remains linear across the typical speech bandwidth without the drift seen in unshielded bare capsules.

Verify pad spacing and bias voltage before ordering

Confirm that your PCB provides the correct bias resistor value and that the 4mm by 2mm footprint matches the solder pads. The 2.6mm wire length suits tight enclosures but offers no strain relief, so plan for mechanical support. Buyers needing a pre-wired boom microphone or a USB-ready module should look elsewhere.

Questions about this item

How much power does each electret condenser cartridge draw when running continuously?

Each cartridge is a passive electret condenser element; it requires only a small bias voltage supplied by the host circuit and draws negligible current during all-day operation.

What bias-voltage source and mounting hardware must I already have to use these 4 mm × 2 mm cartridges?

You need a circuit that provides the standard electret bias voltage through the 2.6 mm leads and a PCB or enclosure with 4 mm × 2 mm mounting holes for the metal-bodied capsules.

Will these 4 mm × 2 mm metal capsules fit the same PCB footprint as the older 6 mm cartridges in my cassette recorder?

No — the 4 mm × 2 mm outline is smaller than a typical 6 mm cartridge, so the existing board would need new mounting holes or an adapter plate.
