Microphones Procurement Notes

Verify the specific suffix NS3 against official Raltron documentation to confirm terminal configuration and sensitivity tolerances. Ensure the operating voltage aligns with the 1.4 V to 5 V specification during system design. Cross-reference the wire lead length and diameter requirements with mechanical constraints before finalizing procurement.

Microphones Selection Notes

Select this model when a unidirectional response is required for voice-frequency applications. The 4.00 mm diameter suits compact enclosures. Confirm that the 500 µA supply current fits the power budget. Compare sensitivity specifications against other Raltron variants if higher gain or different noise characteristics are needed.

Microphones Part Context

This component belongs to the Raltron RMIC series of electret microphones. It shares the Ø4.0 x 1.5 mm form factor with other models in the line but differs in polar pattern and electrical characteristics. The NS3 suffix typically denotes specific termination or sensitivity variations within the product family.

Microphones Replacement Considerations

The RMIC-110-5-4015-NS2 is listed as a related variant, potentially differing in sensitivity or termination. Verify mechanical compatibility and electrical parameters before substitution. No other direct substitutes are confirmed in public data.
