Unique-Bargains Mini 2 Pin 66 DB Condenser Pickup Electret Microphone 6mm x 5mm

SKU CH-BATB-A5BGE

A pack of ten miniature electret condenser microphones with a 50 Hz to 20 kHz frequency range and up to 66 dB sensitivity

  • High sensitivity captures quiet sounds at up to 66dB
  • Wide 50 to 20kHz range records full audio spectrum
  • Low 500uA current draw extends battery life
  • Operates from 1.5V to 10V for flexible power options
  • Compact 6mm by 5mm size fits tight spaces

Mini electret microphone for compact audio capture

The Unique-Bargains Mini 2 Pin condenser pickup measures 6mm by 5mm and is supplied in a pack of five. It targets builders who need a tiny, through-hole microphone element for space-constrained prototypes, hobby circuits or replacement work where a standard capsule will not fit.

Two-pin through-hole mount

The element mounts directly on a PCB via its two pins and operates from 1.5V to 10V with a standard 3V bias. Maximum current draw is 500uA, so it can run from a simple resistor-fed supply or a low-power codec without a dedicated regulator stage.

Steady response across the audible band under

Sensitivity spans -48dB to 66dB across a 50Hz to 20kHz range, and the signal-to-noise ratio exceeds 66dB. These figures hold while the microphone is powered continuously, making it suitable for always-on listening nodes or long-duration recording rather than only brief voice prompts.

Questions about this item

How long can the 500 uA current draw run before battery voltage drops below 1.5 V?

At the maximum 500 uA draw a 3 V cell stays above the 1.5 V minimum until the cell itself is depleted; actual run-time depends on the battery capacity you choose.

What is the self-noise level when the microphone runs continuously?

The signal-to-noise ratio is specified as greater than 66 dB, so self-noise remains well below the signal floor during all-day operation.

What voltage source must the circuit already provide for the microphone to operate?

The circuit must supply between 1.5 V and 10 V; standard operation is at 3 V.
