WM-65A103

Overview

The WM-65A103 is a small-size unidirectional electret condenser microphone capsule designed for general audio applications. It features an integrated FET impedance converter to ensure stable signal output. The device operates within a voltage range of 2 V to 10 V and delivers a sensitivity of -50 dB ±4 dB at 94 dB SPL (referenced to 1 V/Pa). Its frequency response spans from 100 Hz to 12 kHz, making it suitable for Hi-Fi sound reproduction and playback systems. The component utilizes solder pads for surface mounting.

Feature Summary

Unidirectional acoustic design for focused sound capture
Integrated FET impedance converter for signal stability
Compact form factor suitable for space-constrained assemblies

Applications

Hi-Fi sound systems
Audio playback devices
General-purpose microphone modules

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to integration. Confirm that the solder pad footprint matches the PCB layout requirements. Ensure operating voltages remain within the specified 2 V to 10 V range to maintain optimal sensitivity and frequency response characteristics.

Selection Notes

Select this component when a compact, unidirectional electret microphone with built-in impedance conversion is required. It is appropriate for applications prioritizing small size and direct soldering capabilities over through-hole mounting. Consider the 100 Hz to 12 kHz bandwidth when evaluating suitability for full-range audio fidelity.

Part Context

This part belongs to Panasonic's line of analog electret condenser microphones. These components are engineered for high reliability in consumer electronics. The series emphasizes miniaturization while maintaining standard electrical interfaces for easy integration into various audio circuits without requiring external pre-amplification stages.
