WBFK-30095-000

Overview

The Knowles WBFK-30095-000 is a balanced armature transducer designed for high-fidelity audio applications. It operates within a frequency range of 1,800 Hz to 20,000 Hz and features a sensitivity of 106 dB SPL/mW at 1 kHz. The device has an impedance of 16 ohms and handles a maximum power input of 1 mW. It utilizes a standard MMCX connector interface for secure attachment. The component is constructed with a ceramic housing and includes a built-in acoustic filter to optimize sound reproduction.

Feature Summary

• High-frequency response optimized for clarity and detail in the treble range
• Compact balanced armature design suitable for dense multi-driver arrays
• Integrated acoustic filter for precise frequency shaping
• Standardized MMCX connection for reliable modular integration

Applications

• High-end in-ear monitor (IEM) headsets
• Multi-driver custom earpieces requiring dedicated treble units
• Professional audio monitoring equipment
• Premium consumer hearing protection devices

Procurement Notes

Verify that the specific suffix matches the required acoustic tuning and housing configuration. Confirm compatibility with existing driver arrays regarding impedance matching and phase alignment. Ensure the MMCX connector type aligns with the cable assembly specifications. Check for any regional compliance certifications required for the end product.

Selection Notes

Select this unit when a dedicated high-frequency driver is needed to extend bandwidth beyond mid-range capabilities. Consider its placement in the crossover network to ensure seamless blending with adjacent drivers. Evaluate the physical dimensions to confirm fit within the target earpiece shell. Assess the total harmonic distortion characteristics against the system's noise floor requirements.

Part Context

This component belongs to the Knowles Balanced Armature family, widely used in precision audio transducers. It serves as a specialized driver for frequencies above 1.8 kHz. The model is part of a broader ecosystem of transducers designed for various frequency bands, allowing engineers to construct complex multi-way speaker systems with optimized performance across the audible spectrum.

Replacement Considerations

Direct substitutes include other Knowles models such as the SWFK series for super-treble roles or different WBFK variants with adjusted sensitivity. Cross-manufacturer replacements require careful evaluation of impedance curves and mechanical mounting constraints to maintain acoustic integrity.
