Procurement Notes
Verify the exact part number against official Knowles documentation to ensure correct specification matching. Confirm availability status with authorized distributors as supply levels may vary. Ensure compliance with relevant regulatory standards for medical device components before integration into final products.
Selection Notes
Select this component when a rectangular balanced armature speaker with specific impedance characteristics is required. Consider the 264 Ohm impedance and 200 Hz to 5.5 kHz frequency response for compatibility with hearing aid amplifiers. Evaluate the physical dimensions relative to the EF receiver standard for enclosure fit.
Part Context
This component belongs to the CI series of speakers from Knowles. It is categorized under audio devices and transducers. The product is RoHS compliant and utilizes balanced armature technology for efficient sound reproduction in small form factors suitable for wearable medical electronics.
Replacement Considerations
Review datasheets for alternative balanced armature speakers with similar impedance and frequency response. Verify mechanical footprint compatibility if substituting with other models in the CI series or comparable EF-sized receivers.
