AS02508CO-2

Overview

The AS02508CO-2 is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features an oval frame with top porting and an 8-ohm impedance. The device operates within a frequency range of 900 Hz to 20 kHz and delivers a sound pressure level of 87 dB. Rated for 500 mW power handling, it utilizes neodymium magnet technology. The component measures 15x25 mm and is designed for surface or board mounting applications requiring reliable audio output in compact spaces.

Feature Summary

• Oval rectangular frame design optimized for space-constrained enclosures
• Top ported acoustic configuration for directed sound projection
• Neodymium magnetic system providing high efficiency in a small footprint

Applications

• Consumer electronics audio indicators
• Industrial control panel signaling
• Medical device status alerts

Procurement Notes

Verify the specific suffix variant required, as PUI Audio offers modified versions such as -WR-R or -R which may differ in packaging or terminal configuration. Confirm that the 8-ohm impedance and 87 dB SPL meet the target circuit requirements. Ensure the oval dimensions (15x25 mm) fit the designated chassis opening. Check for RoHS compliance if environmental regulations apply to the final assembly.

Selection Notes

Select this model when an oval form factor is necessary to maximize diaphragm area within a rectangular boundary. The 8-ohm impedance is suitable for direct drive from standard low-voltage sources without additional matching transformers. Consider the 87 dB SPL sufficient for audible alerts in moderate ambient noise environments. Evaluate the top-port orientation against enclosure baffle placement to ensure optimal acoustic coupling.

Part Context

This component belongs to PUI Audio's general-purpose speaker line, which emphasizes cost-effective solutions for mass-market electronics. The AS series typically denotes standard electromagnetic transducers with fixed parameters. These speakers are engineered for high-volume manufacturing compatibility and consistent performance across diverse consumer and industrial product categories.

Replacement Considerations

The AS02508CO-2-WR-R is a documented variant with similar electrical characteristics but potentially different packaging or lead finish. Verify mechanical mounting hole patterns and terminal types before substitution to ensure physical compatibility with existing PCB layouts.
