VEK-H-30320-000

Overview

The VEK-H-30320-000 is an omnidirectional electret condenser microphone manufactured by Knowles Acoustics. It features a cylindrical housing with a diameter of 12.7 mm and a depth of 21 mm. The device operates on a supply voltage range of 9 V to 10 V. Its frequency response spans from 100 Hz to 10 kHz, providing analog audio output. The sensitivity is specified as -53 dB ±3 dB at 74 dB SPL. Termination is achieved via wire leads, facilitating integration into various acoustic assemblies.

Feature Summary

• Omnidirectional polar pattern for uniform sound capture
• Electret condenser transducer technology
• Integrated wire lead termination for direct connection

Applications

• Boom microphone configurations
• Rigid microphone assemblies
• Flexible microphone configurations

Procurement Notes

Verify the specific ordering suffix and revision level against the manufacturer's current documentation before procurement. Confirm that the wire lead length and termination style match the design requirements. Ensure the operating voltage range aligns with the target circuit's power supply capabilities to prevent damage or performance degradation.

Selection Notes

Select this component when an omnidirectional response is required within a compact cylindrical form factor. The fixed wire lead termination suits applications where direct soldering or connector attachment is preferred over surface mount options. Consider the 9 V to 10 V operating requirement when designing the biasing circuitry for the internal FET.

Part Context

This model belongs to Knowles' line of boom microphones designed for flexible or rigid configurations. These components are engineered to offer specific performance options such as noise rejection and high-frequency response tuning. The VEK series typically serves professional audio and communication equipment requiring reliable analog signal conversion.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided source material. Verify compatibility with existing mounting hardware and electrical interfaces if considering alternative omnidirectional electret microphones from other manufacturers.
