Unique-Bargains 3pcs Electret Condenser Microphone Cartridge 6mm x 3.5mm

SKU CH-R26H-9R4YM

Three electret condenser microphone cartridges with 3.2 mm wires for audio pickup circuits

  • Electret condenser design for sensitive voice pickup
  • Three cartridges included for multiple replacements
  • 2 mm wire length suits compact circuit layouts
  • 6 mm by 3.5 mm metal housing fits standard microphone slots
  • Red and black colour coding simplifies polarity identification

Three-piece electret condenser set

This pack contains three electret condenser microphone cartridges intended for audio pick-up in recording or voice-control circuits. Each unit measures 6 mm by 3.5 mm and includes a 3.2 mm lead wire. The components are aimed at hobbyists, repair technicians and builders of compact audio devices.

Metal housing and short leads for thermal stability

The external metal body helps dissipate the small heat load generated during normal operation. Low self-noise is inherent to the electret design, and the tiny current draw keeps power consumption negligible in battery-powered projects.

Lightweight cartridges with colour-coded wires

Weighing roughly 1 g each, the capsules add minimal mass to portable builds. Red and black wire insulation simplifies polarity identification during soldering. The short 1.26-inch leads suit tight PCB layouts but limit placement flexibility in larger enclosures.

Questions about this item

How do I install the 6 mm × 3.5 mm cartridge and what step is often missed?

Solder the 3.2 mm leads to the circuit board, observing the marked polarity; the step often missed is confirming the correct terminal before applying heat.

What maintenance or replacement will these condenser cartridges need later?

They are passive capsules with no moving parts; replacement is only needed if the diaphragm is damaged or sensitivity drops after extended use.

What limit appears first when the cartridge runs continuously in a voice-control circuit?

The electret element's charge stability sets the practical limit; prolonged high-SPL exposure can cause gradual sensitivity loss before any mechanical failure.
