Overview
The W-08A is a through-hole piezoelectric buzzer manufactured by East Electronics. It features a diameter of 37.8 mm and operates at a rated voltage of 2.83 V. The device generates an acoustic output of 95 dB when measured at a distance of 50 cm under the rated voltage conditions. It functions at a frequency of 40 kHz. The component is designed for surface mounting via PC pins and supports an operating temperature range from -20°C to 70°C.
Feature Summary
- Generates audible alerts using piezoelectric technology
- Designed for through-hole PCB mounting
- Provides consistent acoustic output at rated voltage
Applications
- Alarm systems
- Buzzer circuits
- Sirens
Procurement Notes
Verify the specific datasheet version for the W-08A, as specifications may vary between manufacturers or revisions. Confirm that the 2.83V rating aligns with your circuit design requirements. Ensure the through-hole package dimensions match your PCB footprint. Check for RoHS compliance status if required by your manufacturing standards. Validate the acoustic performance metrics against your application's noise level needs.
Selection Notes
Select the W-08A when a low-voltage, high-decibel audible indicator is required for through-hole assembly. Consider its 2.83V operating voltage and 40kHz frequency for compatibility with driving circuits. Evaluate the 37.8mm diameter for spatial constraints in the enclosure. Compare its 95dB output against other buzzers if higher or lower volume is needed.
Part Context
East Electronics produces various electronic components, including alarms, buzzers, and sirens. The W-08A belongs to this category of audible signaling devices. It is distinct from resistor networks or LEDs found in other product lines. The component is specifically engineered for direct current or sine wave drive applications requiring clear audio feedback.
Replacement Considerations
No public confirmed substitute part numbers are available for the W-08A. When replacing, ensure the new component matches the 2.83V rating, 37.8mm diameter, and through-hole pin configuration. Verify that the replacement offers similar acoustic output and frequency characteristics.
