Speakers Procurement Notes

Verify component authenticity through authorized Knowles distribution channels or certified distributors. Confirm RoHS compliance status and specific lot traceability requirements prior to procurement. Ensure storage conditions meet manufacturer specifications to preserve acoustic integrity. Cross-reference datasheet revisions to confirm terminal plating and packaging details match project requirements.

Speakers Selection Notes

Select this model when high acoustic efficiency is required within strict dimensional constraints. The 160 Ohm impedance suits driver circuits designed for higher voltage swings rather than low-impedance power amplifiers. Evaluate the 200 Hz to 6.3 kHz bandwidth against target application frequency responses. Consider the balanced armature mechanism for durability compared to dynamic counterparts in vibration-prone environments.

Speakers Part Context

This component is part of the Knowles EF/FEF series of miniature receivers. These devices are engineered for high-reliability applications where size and acoustic performance are critical. The series typically utilizes advanced magnetic materials and precision diaphragms to maintain consistent performance across temperature variations and operational lifespans.

Speakers Replacement Considerations

Direct substitutes include other Knowles EF-series receivers with matching 160 Ohm impedance and similar dimensional footprints. Verify mechanical compatibility and acoustic equivalence before substitution. Consult official Knowles documentation for approved alternative part numbers within the same product family.
