P4020004NM67WER

Speakers Overview

The Stetron P4020004NM67WER is a general-purpose dynamic loudspeaker with dimensions of 40 x 20 x 9.0 mm. It features a nominal impedance of 4 Ohms and a rated power handling capacity of 2.5 W. The frequency response spans from 650 Hz to 10 kHz, with a resonant frequency (Fo) of 650 Hz. The unit utilizes a top round design within a rectangular frame and complies with RoHS standards.

Speakers Feature Summary

• General-purpose dynamic loudspeaker construction
• RoHS compliant environmental standard
• Top round driver configuration in rectangular frame

Speakers Applications

• Consumer electronics audio output
• Industrial control panel indicators
• General purpose alarm systems

Speakers Procurement Notes

Verify the specific suffix 'WER' against the manufacturer's current datasheet to confirm material composition and termination type. Ensure the 4-ohm impedance matches the amplifier output requirements. Confirm RoHS compliance documentation is available for regulatory adherence in the target market.

Speakers Selection Notes

Select this component when a compact 40x20mm form factor is required for space-constrained enclosures. The 4-ohm impedance suits low-voltage audio circuits. Consider the 2.5W power rating for moderate volume applications where high-fidelity reproduction is not the primary objective.

Speakers Part Context

This part belongs to Stetron's general-purpose loudspeaker series, designed for cost-effective audio solutions. It shares dimensional similarities with other models in the P-series but differs in impedance and power ratings. The product line focuses on reliable performance for mass-market electronic devices.

Speakers Replacement Considerations

Direct substitutes must match the 40x20x9mm footprint and 4-ohm impedance. Verify that alternative speakers maintain similar sensitivity and frequency response characteristics to ensure acoustic compatibility without circuit modification.
