PB-3020-2

Alarms, Buzzers, And Sirens Overview

The PB-3020-2 is a piezo buzzer manufactured by Soberton Inc., designed for audio indication and alert applications. It operates on a DC input with a rated voltage of 3V and supports a functional range of 2 to 5V. The device generates a single tone at a frequency of 3.5kHz. It delivers a sound pressure level of 90dB measured at 3V and a distance of 30cm. The component utilizes externally driven transducer technology and features through-hole mounting for integration into electronic circuits.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric transducer technology for reliable acoustic signal generation
• Externally driven design requiring no internal driver circuitry
• Single-tone operating mode for consistent audio alerts
• Through-hole termination method for secure board attachment

Alarms, Buzzers, And Sirens Applications

• Audio indicators in consumer electronics
• Alarm systems requiring audible alerts
• General-purpose buzzer applications in control panels

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix and package configuration against the official Soberton Inc. datasheet before finalizing procurement. Ensure that the required voltage range and sound pressure level specifications align with the target application's acoustic requirements. Confirm lead times and availability directly with authorized distributors, as stock levels may fluctuate. Cross-reference the part number with the manufacturer's current lifecycle status to ensure long-term supply stability.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a simple, cost-effective piezo buzzer is required for basic tone generation. The 3.5kHz frequency and 90dB SPL provide adequate audibility for standard alerting tasks. Consider the through-hole form factor if surface-mount options are not suitable for the mechanical constraints of the assembly. Evaluate the 2 to 5V operating range to ensure compatibility with the system's power supply rails without additional regulation.

Alarms, Buzzers, And Sirens Part Context

The PB-3020-2 belongs to the audio products category within Soberton Inc.'s portfolio, specifically under alarms, buzzers, and sirens. It serves as a fundamental active or passive piezo element depending on drive circuitry, though it is specified as externally driven. This model is distinct from speaker series like the SP-1510, focusing instead on discrete tone generation rather than wide-frequency audio reproduction.

Alarms, Buzzers, And Sirens Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing footprints and electrical parameters if considering alternative manufacturers.
