AS05404PS

Overview

The PUI Audio AS05404PS is a general-purpose electromagnetic speaker featuring a round cone with a rectangular frame. It operates at a nominal impedance of 4 Ohms and supports a rated input power of 10 Watts, with a maximum input power of 12 Watts. The device exhibits a resonant frequency of 115 Hz and an output sound pressure level of 82 dB. Its operational frequency range extends from 115 Hz to 20 kHz. The unit utilizes SMD/SMT mounting technology for board integration.

Feature Summary

• Round cone design integrated within a rectangular frame structure
• SMD/SMT surface mount technology for automated assembly
• Electromagnetic transduction mechanism

Applications

• General-purpose audio output devices
• Consumer electronics assemblies requiring surface mount speakers
• Industrial control panels with audio feedback needs

Procurement Notes

Verify the specific datasheet version provided by PUI Audio or authorized distributors to confirm exact mechanical tolerances and soldering profiles. Ensure the selected variant matches the required impedance and power ratings for the target circuit. Cross-reference the RoHS compliance status with current regulatory requirements for the destination market before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for space-constrained designs. The 4-ohm impedance aligns with standard low-voltage amplifier outputs. Consider the 115 Hz lower frequency limit when designing enclosures for bass response. The rectangular frame facilitates stable mounting on printed circuit boards compared to purely circular frames.

Part Context

This model belongs to the PUI Audio series of electromagnetic speakers designed for modern electronic manufacturing. It represents a shift toward surface-mount technologies in audio components, allowing for reduced assembly costs and improved consistency in high-volume production environments compared to traditional through-hole alternatives.

Replacement Considerations

Direct substitutes must match the 4-ohm impedance, 10W rating, and SMD form factor. Verify that alternative models maintain the 115 Hz resonant frequency and similar SPL characteristics to ensure acoustic performance parity in the existing enclosure design.
