FH-23605-000

Speakers Overview

The Knowles FH-23605-000 is a miniature balanced armature receiver designed for high-fidelity audio applications. It features a rectangular top port configuration with side porting to optimize acoustic output in compact enclosures. The unit operates within a frequency range of 200 Hz to 6.8 kHz and presents an impedance of 500 Ohms. With a sensitivity rating of 100 dB, this component delivers efficient sound pressure levels suitable for demanding wearable and portable electronics where space constraints are critical.

Speakers Feature Summary

• Balanced armature transducer technology for precise audio reproduction
• Rectangular form factor with side port design for directional sound projection
• High sensitivity output optimized for low-power mobile devices

Speakers Applications

• In-ear monitors and high-end earphones
• Wearable audio devices requiring compact drivers
• Portable hearing assistance equipment

Speakers Procurement Notes

Verify the specific suffix and packaging format when ordering, as distributors may list variations in reel quantities or tape specifications. Confirm that the procurement includes only the bare driver element, as accessories such as housings, wires, or crossover networks are not integrated into this part number. Ensure compatibility with your assembly process regarding solder pad dimensions and thermal requirements during reflow.

Speakers Selection Notes

Select this component when a 500 Ohm impedance matches your amplifier output stage and a 100 dB sensitivity meets your volume requirements. The 200 Hz to 6.8 kHz bandwidth defines its tonal character; ensure this range aligns with your target audio profile. Consider the physical dimensions and side-port orientation relative to your enclosure design to maintain acoustic integrity and prevent blockage.

Speakers Part Context

This model belongs to Knowles' extensive portfolio of micro-speakers and receivers. It utilizes balanced armature technology, distinct from dynamic drivers, offering superior transient response and efficiency in small form factors. The FH series is engineered for integration into tight spaces typical of modern consumer electronics and specialized medical audio devices.

Speakers Replacement Considerations

Direct substitutes must match the 500 Ohm impedance, 100 dB sensitivity, and rectangular package dimensions. Verify that alternative models support the same 200 Hz to 6.8 kHz frequency response and side-port configuration to ensure acoustic performance consistency without redesigning the housing.
