PSR-40N08A05-JQ

Speakers Overview

The PSR-40N08A05-JQ is a general-purpose magnetic speaker manufactured by Mallory Sonalert Products Inc. It features an 8-ohm voice coil impedance and a rated input power of 250 mW, with a maximum input capacity of 500 mW. The device operates within a frequency range of 500 Hz to 5 kHz, characterized by a lowest resonance frequency of approximately 500 Hz. It delivers a sound pressure level of 89 dB and utilizes a top round port configuration for acoustic output.

Speakers Feature Summary

• General-purpose magnetic transducer technology
• Top round port acoustic design
• Low resonance frequency operation

Speakers Applications

• General audio indication
• Industrial control panels
• Consumer electronics signaling

Speakers Procurement Notes

Verify the specific suffix JQ against official Mallory documentation to confirm exact packaging or terminal variations. Ensure the 8-ohm impedance matches the target circuit load requirements. Confirm RoHS compliance status through current manufacturer certificates before finalizing procurement specifications.

Speakers Selection Notes

Select this component when a compact, low-power indicator is required. The 250 mW rating suits battery-operated or low-voltage logic circuits. The 8-ohm impedance allows direct interfacing with standard audio drivers without complex matching networks. Consider the 89 dB SPL for audible alerts in moderate noise environments.

Speakers Part Context

This unit belongs to the PSR series of speakers from Mallory Sonalert. The series spans frequencies from 350 Hz to 20 kHz with varying SPL capabilities. This specific model represents the lower-frequency, general-purpose segment of the lineup, designed for reliable tone generation rather than high-fidelity reproduction.

Speakers Replacement Considerations

Direct substitutes must match the 8-ohm impedance, 250 mW power handling, and physical mounting dimensions. Verify that alternative components maintain the 500 Hz minimum resonance frequency to ensure similar acoustic performance characteristics.
