Speakers Procurement Notes

Verify the specific datasheet version when sourcing this component, as manufacturer documentation may undergo revisions. Confirm that the 3.63 Ohm impedance and 1 W power rating align with your system's amplifier output capabilities. Ensure mechanical dimensions fit within the intended enclosure constraints. Check for any recent product change notices or end-of-life announcements from Peerless by Tymphany prior to finalizing procurement plans.

Speakers Selection Notes

Select this model for applications requiring a compact full-range solution with aluminum cone characteristics. The 1 W power rating suggests suitability for low-power or passive radiator configurations rather than high-output main drivers. Consider the 250 Hz lower frequency limit when designing crossover networks or enclosure volumes. The top port orientation must be accounted for in the physical layout of the final assembly.

Speakers Part Context

This component belongs to the PMT series of micro-speakers from Peerless by Tymphany. The series typically focuses on small form factor drivers suitable for portable electronics and compact audio devices. The PMT-18N12AL03-04 specifically denotes the 18 mm diameter variant with aluminum construction and neodymium magnetization, distinguishing it from larger or differently constructed models in the lineup.
