ASX03308-SM-R

Overview

The ASX03308-SM-R is a magnetic exciter manufactured by PUI Audio. It features an 8 Ohm impedance and a rated power of 2 W. The self-resonant frequency is specified at 420 Hz, with a sound pressure level of 77.00 dBA measured at 1W/100mm. The unit has a circular shape with a diameter of 33.00 mm (1.300 inches) and a maximum installation height of 6.50 mm (0.256 inches). It utilizes Neodymium Iron Boron (Nd-Fe-B) magnet material and employs solder eyelet termination for board mounting.

Feature Summary

• Designed as a magnetic exciter for direct surface coupling
• Utilizes high-strength neodymium iron boron magnets
• Features solder eyelet termination for secure electrical connection

Applications

• Direct panel vibration audio generation
• Enclosure resonance excitation
• Compact electronic device audio output

Procurement Notes

Verify the specific suffix 'SM' against official datasheets to confirm exact terminal configuration and mounting variations. Ensure the 2 W power rating aligns with the target application's thermal constraints. Confirm that the 33 mm diameter fits within the designated enclosure space while allowing for proper adhesive or mechanical attachment surfaces.

Selection Notes

Select this component when a low-profile magnetic exciter is required for direct panel coupling rather than air-coupled speaker applications. The 8 Ohm impedance matches standard amplifier outputs. Consider the 77 dBA efficiency for volume requirements in small enclosures. Verify that the operating temperature range meets environmental conditions.

Part Context

This part belongs to the ASX series of exciters from PUI Audio. Exciters differ from standard speakers by transferring vibrational energy directly to a solid surface. This series typically offers compact dimensions suitable for integration into thin consumer electronics or industrial control panels where traditional speaker housings are impractical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, resonant frequency, and physical dimensions with other manufacturer catalogs.
