PUI Audio 8 Ω 0.15 W Miniature Speaker 29.85 mm Dia. 18 mm, 29.85mm

This miniature speaker is a Compact electromechanical transducer designed to provide audible output in low-power electronic systems. It is suitable for installations where space is limited and a clear, single-channel sound source is required, operating across the audio band with a focus on higher-frequency reproduction.

• 8Ω impedance for straightforward driver matching and predictable load
• 0.15W rated power for low-energy signalling and alerts
• 72dB sound level for audible notification at short range
• Mylar cone for stable frequency response and moisture resistance
• 20kHz frequency capability for high-frequency audio content
• RoHS and REACH compliance for use in regulated assemblies

• Suitable for control panels requiring audible feedback
• Ideal for alert tones in automation systems
• Used with handheld test instruments for acoustic signalling
• Can be used for prototype audio in electronics development
• Used for low-power sound alerts in mechanical equipment

Drive the device with a source that sees an 8Ω load and limit input power to 0.15W to avoid thermal stress.

The Mylar diaphragm offers resistance to humidity and provides consistent tonality compared with paper-cone variants.

Allow for a circular footprint of around 29.85mm diameter and clearance for an 18mm depth when installing.

Expect an output near 72dB SPL at close proximity, enclosure acoustics and mounting will influence perceived level.
