Speakers Procurement Notes

Verify the specific revision status and manufacturing date code upon order confirmation, as component specifications may evolve. Confirm that the 625 Ohm impedance rating aligns with the target amplifier output stage requirements. Ensure mechanical clearance matches the 5.19 mm length and 3 mm depth constraints during final enclosure design validation.

Speakers Selection Notes

Select this model when high acoustic clarity and low distortion are prioritized over raw sound pressure level output. The high impedance characteristic requires compatible driver circuitry or specific matching networks. Consider the rectangular geometry for integration into slim-profile wearable devices where standard round drivers do not fit.

Speakers Part Context

This component belongs to Knowles' portfolio of balanced armature speakers, which are widely utilized in premium audio solutions. The EH series represents specialized transducers engineered for distinct form factors, enabling manufacturers to achieve superior audio fidelity within the stringent size limitations of modern consumer electronics and medical devices.

Speakers Replacement Considerations

Direct substitutes require identical 625 Ohm impedance and rectangular dimensions. Verify acoustic sensitivity and frequency response curves against original design specifications to ensure seamless integration without re-engineering the audio path.
