Overview

The Visaton BF 45 is a miniature full-range loudspeaker featuring an aluminum diaphragm. It operates with an impedance of 8 ohms and supports a maximum power handling of 4 watts, with some sources indicating up to 8 watts. The frequency response spans from 90 Hz to 20 kHz. Designed for panel mounting, it requires a cutout diameter of 45 mm. This component is suitable for applications requiring compact audio reproduction within the specified acoustic range.

Feature Summary

• Utilizes an aluminum diaphragm for driver construction
• Designed as a miniature full-range unit
• Supports panel mounting with a 45 mm cutout requirement

Applications

• Miniature audio devices
• Compact speaker enclosures
• General purpose full-range sound reproduction

Procurement Notes

Verify the specific power rating (4W vs 8W) and impedance tolerance against the official manufacturer datasheet before integration. Confirm that the mechanical panel cutout dimensions align precisely with the 45 mm specification to ensure proper installation and acoustic sealing.

Selection Notes

Select this component when a small form factor is required alongside broad frequency coverage. Ensure the application environment stays within the operating temperature range of -25°C to 70°C. Verify that the driving circuit can handle the 8-ohm load without exceeding the rated power limits.

Part Context

This model belongs to the Visaton BF series of miniature speakers. It is distinct from larger rectangular or bipolar capacitor products in the manufacturer's catalog. The BF designation typically indicates a specific line of compact drivers optimized for space-constrained audio projects.
