This component is designed for surface mount applications, providing acoustic output suitable for compact electronic devices requiring precise audio reproduction.

Feature Summary

Balanced armature transducer technology
Side rectangular port design
250 Ohms nominal impedance

Applications

Hearing aids
Medical monitoring devices
Compact communication equipment

Procurement Notes

Verify the specific revision level and packaging format with the manufacturer or authorized distributor before ordering. Ensure that the 250 Ohms impedance matches the target circuit requirements. Confirm RoHS compliance status if required by your manufacturing standards. Check for any recent supply chain updates regarding lead times.

Selection Notes

Select this component when a high-fidelity, low-power audio solution is needed in a small form factor. The balanced armature design offers superior sound quality compared to dynamic drivers at similar sizes. Consider the 250 Ohms impedance for compatibility with existing driver circuits. Evaluate the side port orientation against available PCB space constraints.

Part Context

This part belongs to Knowles' portfolio of precision audio components. Balanced armature receivers are widely used in hearing assistance devices due to their efficiency and size. The CI series represents specialized acoustic solutions tailored for medical and consumer electronics markets.

Replacement Considerations

Check for direct equivalents from Knowles such as the CI-30120-A42, noting differences in impedance (41 Ohms) and sensitivity (124.5 dB). Verify mechanical footprint and electrical characteristics before substitution.
