AS02850MR-R

Overview

The AS02850MR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a 50 mm diameter and operates at a frequency of 950 Hz. The device delivers a sound pressure level of 92 dBA and has an impedance of 50 Ohms. Its power rating is 500 mW. The component utilizes a Neodymium Iron Boron magnet and a Mylar cone. It supports board mount installation with top porting and solder pad termination.

Feature Summary

• Electromagnetic transducer design for audio output
• Top porting configuration for directed sound projection
• Board mount style with solder pad connections
• Neodymium Iron Boron magnetic structure

Applications

• Industrial control panels
• Medical equipment indicators
• Consumer electronics audio feedback
• Security system alerts

Procurement Notes

Verify the specific impedance value of 50 Ohms against circuit requirements to ensure proper matching. Confirm the 500 mW power rating aligns with the driving signal capabilities. Check RoHS compliance status if required by project regulations. Ensure the 950 Hz resonant frequency suits the intended acoustic application. Validate the board mount footprint dimensions during PCB layout.

Selection Notes

Select this model when a 50 Ohm impedance is required for the audio circuit. Consider the 92 dBA output level for applications needing moderate volume. The 50 mm diameter fits standard enclosures allowing space for larger drivers. Top porting is suitable for front-facing sound emission needs. Verify thermal limits within the -20 C to +60 C operating range.
