AS04016MR-R

Overview

The AS04016MR-R is an electromagnetic speaker manufactured by PUI Audio, featuring a round shape with a 40 mm diameter and 10.6 mm depth. It operates at an impedance of 16 Ohms with a power rating of 1 W. The unit utilizes a Neodymium Iron Boron magnet and a Mylar cone, providing a sound pressure level of 78 dBA. Its frequency response extends up to 5.2 kHz, with a self-resonant frequency of 600 Hz. Designed for board mounting via solder lugs, it functions within a temperature range of -20°C to +60°C.

Feature Summary

• Electromagnetic transduction using a neodymium iron boron magnet assembly
• Mylar diaphragm construction for acoustic output
• Solder lug termination for direct circuit board integration

Applications

• General purpose audio indication in electronic devices
• Voice output in consumer appliances
• Alarm signaling systems requiring moderate volume

Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status through official documentation before finalizing procurement. Check for any recent revisions that may affect mechanical dimensions or electrical characteristics. Ensure the solder lug type matches your PCB layout constraints.

Selection Notes

Select this component when a 16 Ohm impedance is required for the audio path. The 1 W power handling capability suits applications needing higher volume than low-power indicators. The 40 mm form factor must fit within the available enclosure space. Consider the Mylar cone material properties for expected acoustic performance in the target environment.
