Speakers Procurement Notes

Verify the specific port configuration required for your design, as datasheets indicate variations between side port (96 dB) and top port (99 dB) options. Confirm RoHS compliance status and lead time availability directly with authorized distributors, as stock levels fluctuate. Ensure the 237 Ohm impedance matches your driver circuit requirements before finalizing procurement orders.

Speakers Selection Notes

Select this component when a balanced armature receiver is needed for frequencies between 200 Hz and 6.6 kHz. The choice depends on whether a side or top port is preferred for acoustic coupling. Consider the 237 Ohm impedance load against your amplifier capabilities. This part is suitable for applications prioritizing compact size and specific mid-range fidelity over wideband response.
