FEH-26796-I02

Speakers Overview

The Knowles FEH-26796-I02 is a board-mount piezoelectric speaker designed for audio signal applications. It features a ferrite magnet and operates at a resonant frequency of 4.5 kHz. The device delivers a sound pressure level (SPL) of 98.5 dBA and presents an impedance of 725 Ohms. Its physical dimensions are 5.18 mm in length by 3.55 mm in width, with a side port configuration.

Speakers Feature Summary

• Side port acoustic design for directional sound projection
• Ferrite magnet construction for stable magnetic performance
• Piezoelectric transduction mechanism

Speakers Applications

• Audio signaling devices requiring high SPL output
• Electronic equipment with limited space constraints
• Industrial control panels and alarm systems

Speakers Procurement Notes

Verify the specific laser marking specifications prior to procurement, as Knowles has issued updates regarding marking standards for this Ferrofluid model series. Confirm that the 725 Ohm impedance matches the driving circuit requirements. Ensure the 98.5 dBA SPL rating meets the audibility needs of the target environment. Validate the 4.5 kHz resonant frequency against system bandwidth limitations.

Speakers Selection Notes

Select this component when a compact form factor is required alongside high acoustic efficiency. The 725 Ohm impedance necessitates compatible driver circuits or matching networks. Consider the 4.5 kHz resonance peak for tone generation rather than wideband audio reproduction. The side port orientation must align with the enclosure's acoustic path.

Speakers Part Context

This component belongs to the Knowles Syfer piezoelectric speaker family. It utilizes a ferrofluid damping process to enhance thermal handling and mechanical stability. The design integrates a ferrite magnet within a small surface-mountable footprint, distinguishing it from larger through-hole alternatives.
