Speakers Procurement Notes

Verify the specific revision level and packaging configuration against the manufacturer's latest datasheet before finalizing procurement orders. Ensure that the receiving facility's handling procedures align with the electrostatic discharge sensitivity requirements typical for balanced armature receivers. Confirm compliance documentation matches the intended regulatory standards for the target market.

Speakers Selection Notes

Select this component when a low-profile, high-efficiency audio solution is required for portable devices. The 110 Ohm impedance allows for direct interfacing with standard audio amplifiers without additional matching networks. Consider the rectangular footprint constraints during PCB layout to ensure adequate clearance for adjacent components and acoustic venting paths.

Speakers Part Context

This model belongs to Knowles' portfolio of precision audio components, specifically engineered for consumer electronics and industrial applications. The balanced armature design distinguishes it from dynamic speakers by offering superior clarity and power efficiency in small enclosures. It represents a specialized solution for OEMs prioritizing acoustic performance within strict spatial limitations.

Speakers Replacement Considerations

Direct substitutes must match the 110 Ohm impedance, 200 Hz–6.3 kHz frequency response, and rectangular SMD package dimensions. Verify pinout compatibility and acoustic output specifications to ensure seamless integration without redesigning the host circuit board or enclosure.
