AS020100MR-R

Overview

The AS020100MR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a diameter of 20 mm and a height of 5.2 mm. The component operates at a resonant frequency of 700 Hz and delivers a sound pressure level of 90 dBA. It has an impedance of 100 Ohms and a power rating of 250 mW. The cone material is Mylar, and it utilizes a rare earth magnet. Electrical connections are made via top solder pads. The unit weighs approximately 3.5 grams and is designed for board mounting applications.

Feature Summary

• Electromagnetic transducer design utilizing a rare earth magnet and Mylar cone
• Top-mounted solder pad termination for surface or through-hole integration
• High impedance configuration suitable for specific driver circuits
• Compact circular form factor optimized for space-constrained enclosures

Applications

• Medical devices requiring audible feedback
• Industrial control panels and instrumentation
• Consumer electronics and home appliances
• Security systems and fire alarms

Procurement Notes

Verify the exact mechanical dimensions and terminal configuration against the official datasheet before finalizing PCB layout. Confirm that the 100 Ohm impedance matches the driving circuit requirements to ensure optimal performance. Check RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range meets your application's environmental conditions.

Selection Notes

Select this model when a high-impedance, low-power speaker is needed for compact designs. The 100 Ohm impedance distinguishes it from standard 8 Ohm speakers, requiring appropriate drive voltage considerations. The top-mount pads facilitate easy assembly in automated processes. Consider the 90 dBA output level relative to the enclosure size and ambient noise levels of the target application.

Part Context

This component belongs to PUI Audio's general-purpose speaker line, which offers various impedances and sizes. The AS series typically includes electromagnetic transducers designed for reliable audio indication. PUI Audio specializes in custom and standard audio solutions for medical, industrial, and consumer markets, providing components that meet rigorous quality standards.

Replacement Considerations

Direct substitutes must match the 100 Ohm impedance, 20 mm diameter, and top-mount termination style. Verify that alternative models maintain similar acoustic output and physical dimensions to fit existing footprints without modification.
