WP-23849-P16

Overview

The Knowles WP-23849-P16 is a waterproof omnidirectional electret condenser microphone designed for analog audio applications. It features an integrated FET amplifier and operates with a sensitivity of -52 dBA ±3dB at 74dB SPL. The device has a frequency response range of 100 Hz to 9.5 kHz and an impedance of 4.4 kOhms. It requires a supply current of 50 µA at a rated voltage of 1.3 V. The component includes 25.4mm litz wires for connection and is engineered to survive immersion in one meter of water, ensuring reliability in wet environments.

Feature Summary

• Waterproof construction capable of surviving immersion in one meter of water
• Omnidirectional acoustic pattern for uniform sound capture from all directions
• Integrated FET amplifier providing high electroacoustic sensitivity
• RFI protection included within the microphone design

Applications

• Wearable electronic devices requiring moisture resistance
• Medical equipment exposed to cleaning fluids or humidity
• Consumer electronics operating in damp environments
• Industrial sensors needing reliable audio input in wet conditions

Procurement Notes

Verify the specific suffix designation against official Knowles documentation to confirm wire length and connector type. Ensure compatibility with existing circuit biasing requirements given the 1.3V rated voltage and 50µA current consumption. Confirm that the 25.4mm litz wire termination meets your assembly specifications. Cross-reference the part number with the latest datasheet to validate performance parameters before integration.

Selection Notes

Select this component when waterproofing is critical for the application environment. The omnidirectional characteristic makes it suitable for general voice pickup where directionality is not required. Consider the small form factor and integrated amplifier for space-constrained designs. Verify that the analog output interface aligns with your system's input requirements.

Part Context

This model belongs to the Knowles WP series of waterproof microphones. The series utilizes electret condenser technology with integral amplification. These components are engineered for durability in harsh environments while maintaining high fidelity audio performance. The WP series is widely used in applications demanding robustness against moisture and physical stress.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific configuration. Evaluate alternative waterproof omnidirectional microphones from the same manufacturer if availability is an issue. Ensure any replacement matches the electrical characteristics and mechanical dimensions.
