AS04008PS-4W-WR

Overview

The AS04008PS-4W-WR is an electromagnetic general-purpose speaker manufactured by PUI Audio. It features a rectangular shape with dimensions of 40 mm in length and 20 mm in width, and a depth of 5.8 mm. The unit operates at an impedance of 8 Ohms with a power rating of 2 W. Its resonant frequency is specified at 380 Hz, and it delivers a sound pressure level of 84 dBA. The cone material is cloth, and the magnet utilizes Neodymium Iron Boron (NdFeB). Electrical connections are made via solder pads, and the device supports board mounting within an operating temperature range of -20°C to +60°C.

Feature Summary

• Utilizes a neodymium iron boron magnetic structure for efficient audio transduction
• Features a cloth cone diaphragm designed for durability and acoustic performance
• Constructed with an ABS frame to provide structural rigidity for panel or board integration

Applications

• Medical equipment audio signaling
• Industrial control panel indicators
• Consumer electronics output devices

Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet, as variations such as WR may denote specific waterproofing or terminal configurations. Confirm RoHS compliance status directly with the supplier documentation prior to procurement. Ensure that the required sound pressure level and frequency response align with the specific acoustic requirements of the target enclosure design.

Selection Notes

Select this component when a compact rectangular form factor is required for space-constrained designs. The 8 Ohm impedance matches standard low-voltage driver circuits commonly found in battery-operated portable devices. Consider the cloth cone material for applications requiring moderate durability over high-frequency extension. Validate that the 2 W power handling capacity meets the peak signal demands of the intended application environment.

Part Context

This model belongs to the AS series of speakers from PUI Audio, which focuses on providing versatile audio solutions for industrial and commercial markets. The series includes various shapes and sizes, with this specific variant offering a balance between compact dimensions and sufficient output for general purpose signaling tasks. PUI Audio leverages decades of experience to ensure reliability in these standardized components.

Replacement Considerations

The AS04008C0-R is a similar oval-shaped electromagnetic speaker from the same manufacturer but features different physical dimensions and a cloth cone. Verify mechanical fitment and electrical parameters before substitution. Other rectangular variants in the AS series may offer different power ratings or impedance values.
