Overview
The Knowles SWFK-33108-000 is a commercial receiver transducer featuring a miniature balanced armature architecture. It utilizes a stationary coil and low-mass diaphragm design to achieve high acoustic efficiency, enabling strong output at low power levels. The component operates with an impedance of 16 ohms and delivers a sensitivity of 111 dB/mW. Its frequency response spans from 5 kHz to 40 kHz. The unit is equipped with a 3.5mm L-shaped gold-plated stereo jack for connection.
Feature Summary
- Miniature balanced armature architecture with stationary coil
- Low-mass diaphragm construction for high acoustic efficiency
- Strong output capability at low power levels
Applications
- Commercial audio receivers
- Transducer assemblies requiring high efficiency
- Low-power audio output devices
Procurement Notes
Verify the specific application requirements against the component's frequency range and impedance specifications. Confirm that the 3.5mm L-shaped connector aligns with the system interface needs. Ensure the commercial grade rating meets the operational environment standards. Cross-reference the manufacturer documentation for any updated compliance or packaging details before finalizing procurement decisions.
Selection Notes
Select this component when a compact solution with high acoustic efficiency is required for commercial applications. The balanced armature design suits environments where low power consumption is critical. Consider the 16-ohm impedance and 111 dB/mW sensitivity for matching with compatible driver circuits. The wide frequency response up to 40 kHz supports detailed audio reproduction needs in specialized receiver systems.
Part Context
This part belongs to the Knowles transducer portfolio, specifically designed for commercial audio applications. It represents a specialized solution within the broader category of speakers and transducers, focusing on miniaturization and efficiency. The product line emphasizes performance in constrained spaces while maintaining high fidelity output characteristics suitable for professional or industrial use cases.
Replacement Considerations
Direct substitutes include other Knowles balanced armature receivers such as the SWFK-31736 or TWFK-31082, which offer similar architectural benefits. When replacing, verify compatibility regarding impedance, sensitivity, and physical connector type to ensure seamless integration without circuit modification.
