AST-030C0MR-R

Overview

The AST-030C0MR-R is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features an ABS housing with a Mylar cone and Neodymium Iron Boron (NdFeB) magnet. The component has a nominal impedance of 100 Ohms and a maximum power rating of 150 mW. Its frequency response ranges from 1.2 kHz to 10 kHz. The unit utilizes top porting for sound output and employs solder pad termination for board mounting. Physical dimensions are approximately 29.7 mm in diameter.

Feature Summary

• Features an ABS housing for environmental durability
• Utilizes Neodymium Iron Boron magnetic structure
• Designed with top porting configuration
• Employs Mylar cone material for acoustic performance

Applications

• General purpose audio indication
• Consumer electronics devices
• Industrial control panels

Procurement Notes

Verify the specific impedance value against the manufacturer's current datasheet, as sources indicate variations between 8 Ohms and 100 Ohms for similar model numbers. Confirm the exact power rating and frequency range requirements for your application before ordering. Ensure the top-port orientation matches your enclosure design constraints.

Selection Notes

Select this component when a compact, round speaker with top porting is required. The 100 Ohm impedance suits high-impedance driver circuits. The ABS housing provides a cost-effective solution for indoor or protected environments. Consider the physical depth and diameter constraints of the target assembly during selection.
