TWFK-30017-000

Overview

The TWFK-30017-000 is a balanced armature receiver manufactured by Knowles Corporation. It features a rectangular form factor with side porting and an impedance of 43 Ohms. The component delivers a sound pressure level of 95dB and operates within a frequency range extending up to 6.5 kHz. Its physical dimensions are 5 mm in length, 2.73 mm in width, and 4.36 mm in height. The device is RoHS compliant and lead-free, designed for integration into compact audio systems requiring precise mid-range reproduction.

Feature Summary

• Utilizes balanced armature technology for high-fidelity audio reproduction
• Rectangular housing design with side port configuration
• Optimized for compact integration in miniature audio devices

Applications

• In-ear monitors and hybrid earphones
• Hearing aids and assistive listening devices
• Mobile phone receivers and communication headsets

Procurement Notes

Verify the specific revision and packaging format directly with authorized distributors or Knowles sales representatives. Confirm that the 43 Ohm impedance specification aligns with your circuit design requirements. Ensure compliance with RoHS standards if required by your manufacturing regulations. Request official datasheets to validate mechanical tolerances before finalizing procurement decisions.

Selection Notes

Select this component when a compact balanced armature driver with side porting is required. The 43 Ohm impedance suits circuits designed for moderate load driving. Consider the 95dB sensitivity for applications needing efficient acoustic output. Verify that the 6.5 kHz upper frequency limit meets the target audio bandwidth specifications for the intended product application.

Part Context

This component belongs to the Knowles SPEAKR series of balanced armature speakers. It is part of the company's portfolio of micro-acoustic solutions developed for consumer electronics and medical devices. The TWFK series represents standard off-the-shelf options for OEMs integrating high-quality audio transducers into space-constrained products.

Replacement Considerations

Direct substitutes require matching the 43 Ohm impedance and rectangular side-port form factor. Evaluate alternative Knowles models such as the SWFK series for similar acoustic performance. Verify mechanical footprint compatibility to ensure seamless integration into existing PCB layouts without redesign.

FAQ

What is the primary acoustic architecture of the TWFK-30017-000?

It utilizes a balanced armature architecture optimized for mid-range frequency reproduction.

Does the TWFK-30017-000 support high-frequency extension beyond 6.5 kHz?

No, the documented frequency response extends up to 6.5 kHz, making it suitable for mid-range tasks rather than full-range audio.
