TWFK-30195-000

Overview

The Knowles TWFK-30195-000 is a dual balanced armature receiver designed for high-fidelity audio applications. It features a rectangular form factor with solder pad termination for surface mount installation. The component operates within a temperature range of 0°C to +63°C and exhibits an impedance of 43 ohms. Its physical dimensions are 5 mm in length, 2.73 mm in width, and 4.36 mm in depth. The unit delivers a sound pressure level of 117 dBa and has a resonant frequency of 6.5 kHz.

Feature Summary

Dual balanced armature driver architecture for enhanced audio reproduction
Rectangular panel mount design with solder pad termination
High sensitivity output capability for efficient signal conversion

Applications

In-ear monitor systems
High-end audio receivers
Professional hearing aid devices

Procurement Notes

Verify the specific datasheet version for the TWFK-30195-000 to confirm exact electrical tolerances and mechanical drawings before integration. Ensure compatibility with existing PCB footprints regarding the 5x2.73mm outline. Cross-reference the manufacturer's latest documentation for any updates on material composition or RoHS compliance status to meet regulatory requirements.

Selection Notes

Select this component when a compact, high-sensitivity dual balanced armature solution is required for space-constrained audio designs. The 43-ohm impedance and 117 dBa sensitivity make it suitable for low-power driving circuits. Consider the rectangular package and solder pad termination for automated assembly processes requiring precise alignment.

Part Context

This part belongs to the Knowles TWFK series of speakers and transducers. It utilizes balanced armature technology, distinct from dynamic drivers, offering precise control over diaphragm movement. The series is engineered for professional audio and medical applications where size and acoustic performance are critical constraints.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative dual balanced armature receivers by matching impedance, sensitivity, and physical dimensions.
