• Voice recognition systems
• Consumer electronic devices
• Communication equipment

Microphones Procurement Notes

Verify the complete part number including suffixes to ensure correct noise cancellation and impedance specifications. Confirm package orientation and solder pad dimensions against PCB layout requirements. Check manufacturer documentation for RoHS compliance status and recommended reflow soldering profiles to prevent component damage during assembly.

Microphones Selection Notes

Select this component when a compact analog microphone with specific noise cancellation capabilities is required. Ensure the host circuit provides the necessary 1.4 V to 5 V bias voltage and can accommodate the 500 µA supply current. Verify that the 5.5 kOhm impedance matches the input requirements of the connected amplifier or ADC stage.

Microphones Part Context

This model belongs to the RMIC series of microphones from Raltron Electronics. The series includes various configurations differing in impedance, voltage range, and noise cancellation performance. This specific variant is distinguished by its 5.5 kOhm impedance and 55 dB SNR, differentiating it from other models in the lineup such as those with 2.2 kOhm impedance.

Microphones Replacement Considerations

Direct substitutes may include RMIC-110-5-6015-NS1, though impedance differences (2.2 kOhms vs 5.5 kOhms) require circuit verification. Other RMIC series parts share similar form factors but vary in electrical parameters; always cross-reference datasheets before substitution.
