PUI Audio Piezo Buzzer Transducer, 12000pF Capacitance, 70 dBA Sound Level - SMT-0940-T-3V-R


This piezo buzzer transducer provides audible signalling for electronics and automation systems, designed for surface-mount integration. It operates across a broad supply range to drive alert tones and status notifications in Compact assemblies, while functioning reliably within typical industrial temperature conditions.

Features and Benefits:


• Operates from 1 to 25V for flexible power arrangements
• Produces 70 dBA sound level for clear audible alerts
• Supports frequencies up to 4500 Hz for high-pitched signalling
• Draws 1 mA supply current for energy-efficient operation
• Integrates via Sn-plated brass termination for robust soldering
• Contains 12 000 pF capacitance piezo element for stable acoustic output

Applications


• Suitable for control panels requiring Compact audible alerts
• Ideal for instrument clusters and handheld diagnostic tools
• Used for rack-mounted equipment status indication
• Can be used for safety annunciation in automation lines
• Used with battery-powered devices needing low-current sounders

What mounting method does it require on a PCB?


It is intended for surface-mount placement with soldered Sn-plated brass terminations to secure electrical and mechanical connection.

How does temperature range affect deployment locations?


The device functions across -30 °C to 85 °C, enabling use in refrigerated, ambient and moderately warm industrial environments.

What electrical characteristic influences resonant behaviour?


The piezo element’s 12 000 pF capacitance affects drive impedance and tone stability under varying drive voltages.

Can it be used in designs with strict regulatory material limits?


The component meets RoHS 2011/65/EU requirements for restricted-substance compliance.

What physical profile should designers allow for in layouts?


The component occupies a Compact footprint with a 9mm length and a 1.9mm height, suitable for space-constrained assemblies.
