PHF-23854-000 is listed in the Speakers range at ChipApex. The manufacturer field lists Knowles. Its product description is SPEAKER 155OHM TOP PORT 110DB. Review the specifications below when checking this part for your BOM.
The PHF-23854-000 is a balanced armature receiver manufactured by Knowles. It features an impedance of 155 Ohms and operates within a frequency range of 200 Hz to 6 kHz. The component delivers a sound pressure level efficiency of 110.0 dB. It utilizes a top rectangular port configuration with dimensions of 0.310 inches (7.87mm). This magnetic technology device is designed for high-fidelity audio reproduction in compact electronic assemblies.
Verify the specific revision code and packaging format directly with the manufacturer or authorized distributors before ordering. Ensure that the acoustic requirements match the application's sensitivity needs. Confirm compliance with relevant environmental standards such as RoHS if required by the end product specifications.
Select this component when a high-efficiency, low-profile receiver is required for voice or narrowband audio applications. The 155 Ohm impedance should be matched to the driving circuitry for optimal power transfer. Consider the physical dimensions and port orientation during the mechanical layout phase to ensure proper acoustic coupling.
This part belongs to Knowles' portfolio of precision audio components, specifically their balanced armature receivers. These components are engineered for reliability and consistent performance in miniaturized form factors. The PHF series is commonly integrated into devices requiring clear audio transmission in space-constrained environments.
Consult official substitution lists from Knowles for direct equivalents. Verify that any alternative component matches the impedance, frequency response, and physical footprint to maintain system integrity.
