PUI Audio 3 W Miniature Speaker 25 mm, 41mm

This miniature speaker is a Compact audio transducer designed for integration into embedded devices and small enclosures where space and moderate audio output are required. It uses a paper cone to reproduce audio up to the upper treble range and is suited to electronic and automation equipment requiring a low-profile sound source that balances size with audible level.

• 4Ω impedance enables efficient drive from low-voltage amplifiers
• Rated at 3W for Compact systems requiring modest power handling
• Frequency response to 20kHz for clear high-frequency reproduction
• High sensitivity delivering 86dBA for audible alerts in noisy areas
• Paper cone construction offering predictable acoustic behaviour
• RoHS-compliant design supporting regulated manufacturing practices

• Suitable for audible alarms in control panels and PLC enclosures
• Ideal for status tones in handheld test equipment
• Used with embedded audio boards in industrial controllers
• Can be used for notification sounds in vending or kiosk devices

The driver requires a nominal 4Ω load, amplifiers and drivers must be specified to drive this impedance without instability.

It is rated for 3W handling under recommended operating conditions, thermal and mechanical limits should be observed for duty-cycled signals.

The device produces around 86dBA sensitivity, which denotes sound pressure level per input and is useful for audible signalling at close proximity.

The low-profile construction simplifies mounting in shallow cavities, designers should verify available cut-out and mounting support to avoid mechanical stress.
