2403 260 00098

Overview

The Knowles 2403 260 00098 is a general-purpose rectangular speaker with a 6-ohm impedance and a 1-watt power rating. It features a top port configuration and delivers a sound pressure level of 73.5 dB when tested at 1 watt per 10 millimeters. The device operates within a frequency range of 300 Hz to 10 kHz. Its physical dimensions are 11 mm by 15 mm by 4.0 mm, utilizing a unique silicone membrane for robustness.

Feature Summary

• Utilizes a unique Knowles silicone membrane for enhanced structural robustness
• Features a top port design for directional sound output
• Constructed as a general-purpose rectangular speaker unit

Applications

• General purpose audio output devices
• Consumer electronics requiring compact speakers
• Industrial equipment needing durable audio components

Procurement Notes

Verify the exact part number format, as distributors may list it with or without hyphens (e.g., 2403-260-00098). Confirm that the required specifications match the 6-ohm impedance and 1-watt power rating. Ensure the top port orientation fits the mechanical design constraints. Check for RoHS compliance status if required by specific project regulations.

Selection Notes

Select this component when a compact, robust speaker is needed for general applications. The 11x15x4.0 mm form factor suits space-constrained designs. The 6-ohm impedance should be compatible with the driving circuit's output stage. Consider the 73.5 dB efficiency for volume requirements in the intended enclosure.

Part Context

This model belongs to the COBRA SIDEFIRE series from Knowles Electronics. It is designed as a surface-mountable or board-mounted acoustic transducer. The product line emphasizes durability through specialized membrane materials, targeting environments where standard speakers might fail due to mechanical stress or environmental factors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mounting holes and electrical connections before considering alternative models from other manufacturers.
