The M4520W Electret Condenser Microphone (ECM) is a precision-engineered electro-acoustic component designed to convert sound waves into clear, stable electrical signals. Featuring a highly sensitive diaphragm paired with premium electret materials, this microphone captures both distinct vocal tones and subtle ambient sounds with exceptional clarity. The physical profile is notably compact, with diameters ranging from 4mm to 10mm, allowing for straightforward integration into space-constrained electronic architectures. Operating efficiently on low voltages between 1V and 10V, it maintains a stable performance footprint suitable for battery-reliant applications.
Encased in a solid metal shell that provides excellent tactile durability and electromagnetic shielding, this component is an essential building block for modern voice input, recording, and noise detection systems. The M4520W offers a standard sensitivity range of -42dB to -25dB, ensuring accurate audio pickup across diverse environments.

The M4520W delivers exceptional sensitivity, precisely calibrated between -42dB and -25dB, to ensure the accurate capture of voice and ambient acoustics. By utilizing a high-precision diaphragm structure, it guarantees clear audio pickup with minimal distortion. Purchasers can select from omnidirectional, unidirectional, or specialized noise-canceling configurations. Combined with an outstanding Signal-to-Noise Ratio (SNR), this microphone excels at extracting human voices while suppressing background noise, making it highly effective in complex industrial settings or outdoor environments where audio clarity is paramount.
Engineered for energy efficiency, these microphones operate smoothly at low voltages ranging from 1V to 10V, drawing minimal current during active use. This ultra-low power footprint is highly advantageous for battery-operated devices, portable electronics, and wireless communication tools, extending the operational life of the final product. The stable electrical performance guarantees a consistent signal output without fluctuation, even during extended, continuous operating periods, thereby reducing the need for frequent maintenance or battery replacements.
Available in miniature dimensions typically spanning 4mm to 10mm in diameter, the M4520W solves space constraint challenges in modern electronic design. To accommodate large-scale automated manufacturing, we provide multiple mounting and soldering options, including Surface Mount Device (SMD), Dual In-line Package (DIP), and wire terminal configurations. Furthermore, the availability of Tape and Reel packaging perfectly aligns with high-speed automated SMT production lines, significantly accelerating assembly processes and reducing labor overhead for large volume runs.
With a broad frequency response range spanning from 50Hz to 16kHz, the microphone effectively captures a full spectrum of low and high-frequency sounds, resulting in a natural, balanced audio reproduction. To protect this pristine audio quality, the M4520W utilizes a premium metal housing that delivers superior electromagnetic shielding. This structural design effectively resists Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI), ensuring that the audio signal remains uncontaminated even when placed near antennas or high-frequency circuitry.
Built to endure, the internal structure and durable materials grant the ECM a remarkable service life exceeding 30,000 to 50,000 hours under standard conditions. Every batch undergoes rigorous quality control, including full acoustic inspections in anechoic chambers, thermal cycling, and accelerated aging tests. This guarantees exceptional acoustic consistency and an extremely low defect rate for bulk orders. Fully compliant with RoHS and REACH international environmental directives, and manufactured under an ISO9001-certified quality management system, these components ensure your finished electronic products can be exported globally without compliance hurdles.
