PUI Audio 0.3 W Miniature Speaker 15 mm Dia.

This miniature speaker is a Compact acoustic transducer intended for integration into electronic assemblies where a discrete audio output is required. It converts electrical signals into continuous audible tones suitable for signalling and alerting within control panels and small devices. The unit is designed for use in confined spaces where a low-profile audio source is needed.

• 8Ω impedance enables straightforward drive from standard amplifiers
• 0.3W rated power supports low-power signalling applications
• 87dB sensitivity provides high-perceived loudness for its size
• Continuous-tone response ensures consistent alert output
• Mylar cone offers stable acoustic performance over time

• Suitable for alarm and alert circuits in automation equipment
• Ideal for audio indication on control panels and instrumentation
• Used with Compact consumer electronics requiring audible feedback
• Can be used for prototypes and PCB-mounted signalling modules
• Suitable for small-scale industrial sensor alert systems

The device reproduces tones up to 20kHz, covering the full audible range and allowing crisp high-frequency alert signals.

Its small 15mm diameter and 13.65mm height permit direct installation on PCBs or within tight enclosures where minimal footprint is required.

The diaphragm is MADE from Mylar, chosen for its dimensional stability and consistent acoustic response in Compact transducers.

The manufacturing conforms to EC directives and RoHS 2002/95 requirements, reflecting restrictions on hazardous substances in components.
