Speakers Procurement Notes

Verify the specific datasheet version from Knowles Electronics to confirm mechanical tolerances and acoustic performance curves. Ensure compatibility with the target application's acoustic chamber design. Confirm that the 260 Ohm impedance matches the driving circuit requirements. Check for any RoHS compliance documentation if required by the end product regulations.

Speakers Selection Notes

Select this component when a balanced armature receiver with a rectangular form factor is required. The 260 Ohm impedance suits specific driver circuits. Consider the 200 Hz to 6.3 kHz frequency response against the desired audio bandwidth. Evaluate the 100 dB SPL output against the necessary volume levels. Verify physical space constraints against the 5.09 x 2.8 x 2.60 mm dimensions.

Speakers Part Context

This part belongs to the Knowles speaker series, specifically utilizing balanced armature technology. It is designed as a surface mount receiver for integration into small form-factor electronics. The rectangular shape distinguishes it from circular counterparts in the same family.
