Overview
The AS05004MR-3-R is a general-purpose piezoelectric speaker manufactured by PUI Audio, Inc. It features a round shape with SMD/SMT termination and top porting. The device operates within a frequency range of 280 Hz to 20 kHz, with a self-resonant frequency of 350 Hz. Key electrical parameters include an impedance of 4 Ohms, a sound pressure level of 100 dBA, and power ratings of 1.5W to 2W. Dimensions are 50 mm in length and 7.2 mm in width.
Feature Summary
- Round piezoelectric transducer design for compact integration
- Surface mount termination style for automated assembly
- Top port configuration for direct sound projection
Applications
- General purpose audio signaling
- Buzzer applications in consumer electronics
- Industrial control panel indicators
Procurement Notes
Verify the specific datasheet version from PUI Audio or authorized distributors to confirm current RoHS compliance status and exact power rating specifications (1.5W vs 2W). Ensure that the 4 Ohm impedance matches the driving circuit requirements. Check lead times as they may vary significantly between suppliers due to manufacturing schedules.
Selection Notes
Select this component when a low-profile, surface-mountable piezo speaker is required. The 4 Ohm impedance and 100 dBA sensitivity suit standard driver circuits. Consider the 50 mm x 7.2 mm footprint for space-constrained designs. Verify thermal limits against the maximum operating temperature of +60°C for the intended environment.
Part Context
This part belongs to PUI Audio's line of piezoelectric speakers and transducers. It is designed for bare mount installation in electronic assemblies. The product is distinct from their MEMS microphone lines, serving specifically as an output transducer rather than an input sensor.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, frequency response, and physical dimensions with other manufacturers' piezo speakers.
