WP-23502-000

Overview

The WP-23502-000 is an analog omnidirectional electret condenser microphone manufactured by Knowles. It operates within a voltage range of 1.3 V to 10 V and draws a supply current of 50 µA. The device features a rectangular pad termination with dimensions of 5.56 mm in length, 3.99 mm in width, and a maximum height of 2.26 mm. It exhibits a sensitivity of -52 dB ±3 dB at 74 dB SPL and maintains an impedance of 4.4 kOhms. The frequency response spans from 100 Hz to 4 kHz.

Feature Summary

• Waterproof construction suitable for demanding environments
• Omnidirectional acoustic pickup pattern
• Analog output signal generation

Applications

• Audio recording devices requiring waterproof durability
• Voice recognition systems
• Consumer electronics with exposed microphone ports

Procurement Notes

Verify the specific revision status and RoHS compliance level prior to procurement, as manufacturing updates may occur. Confirm that the 1.3 V minimum operating voltage aligns with the target system power supply design. Ensure the physical footprint matches the PCB layout requirements for the 5.56 mm x 3.99 mm package.

Selection Notes

Select this component when a rugged, waterproof microphone solution is required for analog audio applications. The wide operating voltage range allows flexibility in power supply design. Consider the 100 Hz to 4 kHz frequency response limitation if high-fidelity audio reproduction outside this band is necessary.

Part Context

This microphone belongs to the WP series, which specializes in waterproof audio components designed for reliability in harsh conditions. The series targets applications where standard microphones might fail due to moisture exposure. It serves as a specialized alternative to non-waterproof counterparts in outdoor or industrial audio equipment.
