ED-30103-000

Speakers Overview

The Knowles ED-30103-000 is a subminiature balanced armature receiver speaker designed for compact audio applications. It features a rectangular form factor with dimensions of 6.32 mm in length, 4.31 mm in width, and 2.97 mm in height. The component operates at an impedance of 33 ohms and delivers a sound pressure level efficiency of 102.5 dB. It is classified under the ED/FED series and is RoHS compliant.

Speakers Feature Summary

• Balanced armature transducer technology for high-fidelity audio reproduction
• Rectangular physical design optimized for space-constrained enclosures
• High acoustic efficiency rating suitable for low-power operation

Speakers Applications

• Mobile communication handsets
• Wireless earpieces and headsets
• Portable medical diagnostic devices

Speakers Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Knowles or authorized distributors before integration. Confirm that the rectangular package dimensions and terminal configuration match the target PCB layout requirements to ensure mechanical compatibility.

Speakers Selection Notes

Select this component when a high-efficiency, small-footprint receiver is required for voice band applications. The 33-ohm impedance matches standard driver outputs, while the 102.5 dB SPL ensures adequate volume in sealed or semi-sealed acoustic chambers without excessive power consumption.

Speakers Part Context

This part belongs to the Knowles ED/FED series of subminiature speakers. These components are engineered for high-volume consumer electronics where size and weight are critical constraints. The series utilizes balanced armature architecture to deliver consistent performance across varying environmental conditions.

Speakers Replacement Considerations

Direct substitutes within the same series include the BF-3037-000, though dimensional and acoustic differences must be evaluated. Cross-referencing impedance and sensitivity specifications is essential when considering alternative manufacturers' offerings.
