AS04008PS-2-R

Overview

The AS04008PS-2-R is an electromagnetic speaker manufactured by PUI Audio, designed for board and frame mounting applications. It features a round shape with a paper cone and ferrite magnet material. The component operates within a temperature range of -40°C to +85°C. Key electrical parameters include an impedance of 8 Ohms, a power rating of 4 W, and a sound pressure level of 90 dBA at 1 meter. The resonant frequency is specified at 250 Hz, with a self-resonant frequency also noted at 250 Hz. Physical dimensions are approximately 71 mm in length, 41 mm in width, and 25 mm in height.

Feature Summary

• Utilizes a ferrite magnet and paper cone construction for acoustic output.
• Supports both frame and board mounting configurations via solder lug terminals.
• Operates reliably across an extended industrial temperature range from -40°C to +85°C.

Applications

• Industrial control panels requiring robust audio signaling
• Medical equipment user interfaces
• Security and fire alarm systems

Procurement Notes

Verify the specific datasheet version before integration, as manufacturing specifications may evolve. Confirm that the solder lug termination type aligns with your PCB or chassis design requirements. Ensure the operating environment stays within the stated -40°C to +85°C limits to maintain performance integrity. Check for any RoHS compliance documentation updates relevant to your region's regulations prior to final procurement.

Selection Notes

Select this model when high power handling (4 W) and wide temperature tolerance are required. The 8 Ohm impedance suits standard amplifier outputs. Consider the physical size constraints carefully due to its larger footprint compared to smaller series variants. The ferrite magnet offers cost-effective performance for non-miniaturized applications where weight is less critical than durability.

Part Context

This component belongs to the AS series of speakers from PUI Audio, which focuses on electromagnetic transducers. The series includes various shapes and sizes tailored for different mounting styles. This specific part represents a higher-power option within the lineup, distinguished by its paper cone and ferrite magnet combination, suitable for demanding environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other models within the AS series based on matching impedance, power rating, and physical dimensions if direct substitution is necessary.
