PUM-3046L-C3310-R

Microphones Overview

The PUM-3046L-C3310-R is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features a unidirectional pickup pattern with a sensitivity of -46dB (±4dB) and a signal-to-noise ratio of 55 dB. The device operates at 2 VDC with a current consumption of 0.5 mA and includes a 2.2 kOhm impedance. It utilizes solder pads for connection and has a diameter of 6 mm.

Microphones Feature Summary

• Unidirectional acoustic design for focused sound capture
• Electret condenser technology for analog audio conversion
• Solder pad termination for direct board integration

Microphones Applications

• Consumer electronic audio input devices
• Voice recognition systems
• Portable communication equipment

Microphones Procurement Notes

Verify the specific suffix C3310-R against official PUI Audio documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing circuit biasing requirements, specifically the 2 VDC supply voltage and 0.5 mA current draw. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Microphones Selection Notes

Select this component when a compact, low-power unidirectional microphone is required for analog audio applications. The fixed 2 VDC operating voltage limits suitability for higher voltage systems without additional conditioning. The solder pad interface necessitates surface-mount assembly processes compatible with the specified package dimensions.

Microphones Part Context

This part belongs to the PUM series of electret condenser microphones from PUI Audio, Inc. The series typically offers various directivity patterns and sensitivity levels. The specific model indicates a standard unidirectional configuration with defined electrical parameters suitable for general-purpose voice capture in consumer electronics.

Microphones Replacement Considerations

Direct substitutes must match the 6 mm diameter, unidirectional pattern, and -46dB sensitivity. Verify pinout compatibility for solder pad connections. Check if alternative manufacturers offer equivalent 2 VDC operation and similar SNR performance.
