AS08304CR-R

Overview

The AS08304CR-R is an electromagnetic buzzer manufactured by PUI Audio, Inc. This component operates at a nominal voltage of 3V DC and produces a sound pressure level of 85 dB at a distance of 10 cm. The device features a resonant frequency of 3.0 kHz and draws a current of 25 mA during operation. It utilizes a through-hole mounting configuration with two pins for electrical connection. The unit is designed for compact electronic applications requiring audible signaling.

Feature Summary

• Electromagnetic transduction mechanism for reliable acoustic output
• Through-hole pin configuration for standard PCB integration
• Compact form factor suitable for space-constrained enclosures

Applications

• Consumer electronics audible alerts
• Home appliance status indicators
• Industrial control panel signaling

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure compatibility with required voltage and frequency specifications. Confirm that the through-hole pin spacing matches the target printed circuit board layout. Check for RoHS compliance requirements if applicable to the end product. Ensure the operating temperature range aligns with the intended environmental conditions of the assembly.

Selection Notes

Select this component when a low-voltage, high-volume production buzzer is required. Consider the 3V DC operating requirement and 25 mA current draw for power budget calculations. Evaluate the 85 dB SPL output against ambient noise levels in the application environment. Verify mechanical dimensions fit within the designated housing constraints before finalizing the design.

Part Context

This part belongs to PUI Audio's line of electromagnetic buzzers. These components are distinct from piezoelectric alternatives by their use of a coil and diaphragm system. The series typically offers consistent performance across various consumer and industrial sectors. The model number indicates specific electrical and mechanical characteristics defined by the manufacturer.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Ensure substitute parts match the 3V DC rating, 3.0 kHz frequency, and 85 dB SPL output. Verify identical pinout and mechanical footprint to avoid PCB redesign. Confirm equivalent current consumption to maintain power supply stability.
