SW250808-1

Overview

The SW250808-1 is a standard piezoelectric buzzer element manufactured by DB Unlimited. It operates at a resonant frequency of 3.5 kHz and supports a maximum input voltage of 20 V peak-to-peak. The component features a capacitance of 12,000 pF measured at 1 kHz. Its physical dimensions include a diameter of 27.00 mm (1.063 inches). The device is designed for operation within a temperature range of -20°C to 60°C.

Feature Summary

• Generates audible sound signals using piezoelectric technology
• Standard form factor with through-hole or surface-mount compatibility
• Operates on direct current input with specified voltage limits

Applications

• General purpose audio indication in electronic devices
• Status signaling in consumer appliances
• Alarm systems requiring simple acoustic output

Procurement Notes

Verify the specific ordering suffix and package variant against the official DB Unlimited datasheet before purchase. Confirm that the required operating voltage and frequency match the application design specifications. Ensure the supplier provides genuine components from authorized channels to guarantee performance consistency and reliability standards are met.

Selection Notes

Select this component when a 3.5 kHz acoustic output is required for system alerts. Consider the 27 mm diameter for available board space constraints. Evaluate the 20 V peak-to-peak voltage limit against the driving circuit capabilities. Check the -20°C to 60°C operating range against environmental conditions.

Part Context

This part belongs to the DB Unlimited piezoelectric buzzer family, categorized under passive acoustic indicators. It serves as a basic sound generation element distinct from active buzzers or complex speaker assemblies. The product line focuses on cost-effective, reliable acoustic solutions for industrial and consumer electronics applications.

Replacement Considerations

Cross-reference compatible substitutes such as the SW230704-1 or SP660308-1 from the same manufacturer. Verify that alternative parts match the 3.5 kHz frequency and 27 mm diameter requirements. Ensure electrical parameters like capacitance and voltage ratings remain compatible with the existing circuit design.
