AST-1732MR-R

Overview

The AST-1732MR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a 17 mm diameter round design with a Mylar cone and Neodymium Iron Boron magnet. The unit operates at 32 Ohms impedance with a power rating of 100 mW. It delivers a sound pressure level of 90 dBA and has a resonant frequency of 1.7 kHz. The component utilizes solder pin termination for PCB mounting and functions within a temperature range of -20°C to +60°C.

Feature Summary

• Compact electromagnetic transducer design suitable for space-constrained applications
• High-efficiency Mylar cone construction paired with neodymium magnet technology
• Direct PCB integration via solder pin termination style

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• Medical device acoustic signaling

Procurement Notes

Verify the specific manufacturer part number against official datasheets before procurement. Confirm that the 32 Ohm impedance and 100 mW power rating align with your circuit design requirements. Ensure the solder pin termination method is compatible with your printed circuit board assembly process. Check for RoHS compliance status in the latest documentation.

Selection Notes

Select this component when a compact form factor is required alongside moderate acoustic output. The 32 Ohm impedance suits standard low-power driver circuits. Consider the 1.7 kHz resonance for tone-specific applications rather than wideband reproduction. Verify mechanical clearance for the 12.7 mm height dimension during enclosure design.

Part Context

This model belongs to the PUI Audio AS series of speakers. The series includes various impedances and sizes tailored for different acoustic needs. The AST-1732MR-R specifically targets applications requiring a balance between size and sound pressure level. It represents a standard offering in their electromagnetic transducer lineup.

Replacement Considerations

No public substitute part numbers are confirmed for this specific component. Evaluate other PUI Audio models with similar dimensions and electrical characteristics if direct replacement is necessary.
