Speakers Procurement Notes

Verify the specific ordering suffix and terminal configuration against the manufacturer's current datasheet before procurement. Confirm that the 3.91 Ohm impedance and 1.5 W power handling align with the target amplifier output capabilities. Ensure mechanical mounting dimensions match the intended enclosure design to prevent interference.

Speakers Selection Notes

Select this component when a high-efficiency, small-form-factor full-range driver is required. The aluminum cone offers distinct transient characteristics compared to paper or composite cones. Consider the 3.91 Ohm impedance for matching with low-impedance amplifier stages. Evaluate the 78.5 dBA sensitivity for efficiency requirements in passive designs.

Speakers Part Context

This model belongs to the PMT series of micro full-range drivers. It utilizes a round shape and top-mount configuration. The series is designed for integration into consumer electronics where size and weight are critical constraints. The neodymium magnet provides strong magnetic flux density within a minimal volume.

Speakers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 30 mm diameter, 3.91 Ohm impedance, and 1.5 W power rating. Mechanical compatibility must be verified independently.
