TO38-31019-B21

Overview

The TO38-31019-B21 is an omnidirectional microphone manufactured by Knowles. It belongs to the company's line of acoustic sensors designed for audio signal capture. The component is packaged in a tray and is compliant with RoHS standards, indicating it is lead-free. This specific model is categorized under general microphones within the manufacturer's portfolio.

Feature Summary

Omnidirectional directional properties for uniform sound pickup
RoHS compliant and lead-free construction

Applications

General audio signal capture
Acoustic sensing applications

Procurement Notes

Verify the exact datasheet specifications directly from Knowles or authorized distributors before integration. Confirm that the omnidirectional characteristic aligns with your acoustic design requirements. Ensure the tray packaging format is compatible with your assembly equipment. Check for any specific handling instructions regarding the microphone element.

Selection Notes

Select this component when an omnidirectional response is required for consistent audio input from all angles. Consider the physical dimensions and mounting constraints associated with the TO38 package style. Evaluate if the standard sensitivity and frequency response meet your application needs compared to other Knowles microphone variants.

Part Context

This part is part of Knowles' broader microphone family, which includes various electret and MEMS options. The TO38 designation typically refers to a specific form factor used in their legacy or specialized product lines. It serves as a fundamental acoustic transducer for converting sound waves into electrical signals.

Replacement Considerations

Consult official substitution guides for direct equivalents. Verify pinout compatibility and acoustic performance metrics against alternative models from Knowles or other manufacturers to ensure seamless integration without redesigning the host circuitry.
