AS02504PR-N50-R

Overview

The AS02504PR-N50-R is a round electromagnetic speaker manufactured by PUI Audio, Inc. It features a paper cone and rubber surround with a 4-ohm impedance and a power rating of 2 watts. The device delivers a sound pressure level of 79 dBA and has a self-resonant frequency of 280 Hz. Its operational frequency range spans from 250 Hz to 20 kHz. The unit measures 22 mm in diameter and 6.7 mm in height, utilizing board mount solder pad termination for installation.

Feature Summary

• Utilizes a paper cone and rubber surround construction for acoustic performance
• Designed for board mount installation via solder pads
• Operates within a wide frequency range from 250 Hz to 20 kHz

Applications

• General purpose audio output devices
• Industrial electronic equipment requiring low latency audio
• Consumer electronics with panel or board mounting requirements

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct configuration. Confirm that the paper cone material and rubber surround specifications match the intended environmental conditions. Ensure the 4-ohm impedance aligns with the driving circuit design. Check RoHS compliance status if required for the target market regulations.

Selection Notes

Select this component when a compact 22 mm round speaker is required for general purpose applications. The 4-ohm impedance suits standard low-voltage audio drivers. The paper cone offers distinct acoustic characteristics compared to polymer alternatives. Consider the 6.7 mm depth constraint for enclosure design. Verify the 2-watt power handling capability against peak signal requirements.

Part Context

This model belongs to the AS series of speakers from PUI Audio, Inc., which are designed for various electronic applications. The series includes variants with different impedances, power ratings, and cone materials. This specific part emphasizes a paper cone and rubber surround combination, distinguishing it from Mylar-cone counterparts in the same product line.

Replacement Considerations

Direct substitutes may include other PUI Audio models with identical 4-ohm impedance and similar dimensions. Cross-referencing the 22 mm diameter and 6.7 mm height is critical for mechanical fit. Ensure the replacement maintains the 2-watt power rating and comparable sensitivity levels.
