NS28D-0402-07

Speakers Overview

The NS28D-0402-07 is a general-purpose round speaker manufactured by Huizhou N Acoustics Co., Ltd. It features a nominal impedance of 4 Ohms and a power handling capacity of 3 Watts. The frequency response range spans from 400 Hz to 20 kHz, with a sound pressure level (SPL) rating of 91 dB.

Speakers Feature Summary

• Round form factor design suitable for compact audio enclosures
• General-purpose acoustic performance across mid-to-high frequencies
• Standard 4 Ohm impedance matching common amplifier outputs

Speakers Applications

• Consumer electronics audio output modules
• Portable device speaker integration
• General purpose sound reproduction systems

Speakers Procurement Notes

Verify the specific datasheet version for mechanical dimensions and terminal configuration before integration. Confirm RoHS compliance status if required by your manufacturing standards. Ensure the 4 Ohm impedance matches your amplifier's output specifications to prevent damage or distortion. Check packaging quantities directly with the distributor as these may vary.

Speakers Selection Notes

Select this component when a 4 Ohm, 3 Watt speaker is required for applications needing a frequency response up to 20 kHz. The 91 dB SPL rating indicates moderate efficiency. Consider the round shape constraint for your enclosure design. Compare against similar models like NS28D-0402-10 if different power or frequency characteristics are needed.

Speakers Part Context

This part belongs to the NS28D series of speakers from Huizhou N Acoustics. The series typically includes various impedance and power ratings. The NS28D-0402-07 specifically denotes the 4 Ohm, 3 Watt variant within this product line, distinguished by its specific frequency response and SPL characteristics compared to other series members.

Speakers Replacement Considerations

NS28D-0402-10 is a related model in the same series but differs in power rating (2W) and frequency range (160Hz-16kHz). Verify mechanical fit and electrical compatibility before substitution.
