9200-153299

Overview

The Knowles 9200-153299 is a high-performance electret condenser microphone capsule designed for precision audio capture. It features a back-electret design with a pre-amplified output stage integrated directly onto the PCB. The component offers a consistent frequency response suitable for voice and general acoustic sensing applications. Key electrical characteristics include a nominal sensitivity of approximately -42 dBV/Pa and an operating voltage range typically supported by standard biasing circuits. The physical construction utilizes a durable metal housing to protect the internal diaphragm and electronics from environmental factors while maintaining acoustic transparency.

Feature Summary

• Integrated pre-amplifier for direct signal interfacing
• Back-electret transducer technology for stable performance
• Metal housing construction for mechanical durability

Applications

• Voice recognition systems
• Consumer electronic audio input devices
• Industrial acoustic monitoring sensors

Procurement Notes

Verify the specific datasheet revision corresponding to part number 9200-153299 before integration, as manufacturing updates may alter pinout configurations or sensitivity tolerances. Confirm compatibility with your target circuit's bias voltage requirements and impedance matching specifications. Ensure that the procurement source provides authentic components with traceable origin documentation to guarantee acoustic consistency and long-term reliability in final assembly processes.

Selection Notes

Select this component when a compact, pre-amplified electret solution is required for voice-band applications. Evaluate the need for its specific sensitivity level against alternative microphones in your design. Consider the mounting constraints imposed by its metal housing dimensions. Verify that the available supply chain supports the required volume for your production timeline without compromising component authenticity or quality standards.

Part Context

This model belongs to Knowles' broader portfolio of electret condenser microphones, which are widely utilized in consumer electronics and industrial equipment.
