VEK-F-30352-000

Overview

The VEK-F-30352-000 is an analog electret condenser microphone manufactured by Knowles. It features an omnidirectional polar pattern and operates within a frequency range of 100 Hz to 10 kHz. The device exhibits a sensitivity of -53 dB ±2 dB at 74 dB SPL and has an impedance of 4.4 kOhms. It supports a maximum current rating of 50 uA and utilizes PC pins for termination. The physical height is limited to 5.20 mm, making it suitable for compact electronic assemblies requiring reliable audio capture.

Feature Summary

• Omnidirectional acoustic design for uniform sound pickup from all directions
• Analog output signal generation via integrated electret condenser element
• Compact subminiature form factor with low profile dimensions

Applications

• Surveillance and security systems
• General purpose audio recording devices
• Consumer electronics requiring voice input

Procurement Notes

Verify the specific datasheet version provided by Knowles Electronics to confirm mechanical drawing tolerances and electrical characteristics. Ensure that the application circuitry matches the specified 4.4 kOhm impedance and 50 uA current rating requirements. Cross-reference the pin configuration with the target PCB layout to guarantee correct polarity and connection integrity during assembly.

Selection Notes

Select this component when an omnidirectional response is required in space-constrained environments. The fixed sensitivity and impedance values dictate preamplifier gain settings. Consider the operating temperature range and humidity resistance if deployed in non-standard environmental conditions. Validate compatibility with existing board space against the 5.20 mm maximum height constraint.

Part Context

This microphone belongs to the VEK-F series of subminiature electret microphones produced by Knowles. The series is engineered for high-volume consumer applications where size and cost efficiency are critical. It represents a standard solution for basic audio sensing tasks in portable and stationary electronic devices.

Replacement Considerations

Consult official Knowles documentation for direct cross-references. Alternative models may offer different sensitivity levels or impedance values, necessitating circuit adjustments.
