PSR-57F08S02-JQ

Speakers Overview

The PSR-57F08S02-JQ is a general-purpose speaker manufactured by Mallory Sonalert Products Inc. It features an 8 Ohm voice coil impedance with a tolerance of ±15% at 800 Hz and 1.0 V. The device has a rated input power of 0.25 W and a maximum input power handling capability of 0.50 W. Its frequency response ranges from 350 Hz to 5 kHz, with a lowest resonance frequency (Fo) of 350 Hz ±20%. The speaker delivers a sound pressure level of 90 dB and utilizes top port mounting.

Speakers Feature Summary

• General-purpose audio output component suitable for standard signal reproduction applications.
• Capable of handling up to 0.50 W maximum input power while maintaining a rated operation at 0.25 W.
• Features an 8 Ohm impedance design compatible with common driver circuits.

Speakers Applications

• Industrial control panel audio indicators
• General purpose alarm systems requiring moderate volume output
• Consumer electronics audio feedback modules

Speakers Procurement Notes

Verify the specific impedance tolerance and resonance frequency requirements against your circuit design before ordering. Confirm that the 0.25 W rated power and 0.50 W maximum power handling are sufficient for your intended duty cycle and acoustic environment. Ensure the top round mounting style and physical dimensions fit within the designated enclosure space. Check for any specific RoHS or REACH compliance documentation if required by your manufacturing standards.

Speakers Selection Notes

Select this model when a compact, general-purpose speaker is needed for mid-range frequency reproduction between 350 Hz and 5 kHz. It is appropriate for applications where 90 dB SPL is adequate for audible alerts. Consider the 8 Ohm impedance for compatibility with standard amplifier outputs. Evaluate the thermal limits given the 0.25 W rated power to prevent damage during continuous operation.

Speakers Part Context

This component belongs to the Mallory Sonalert products line, which specializes in audio devices including buzzers, sirens, and speakers. The PSR series typically offers robust construction for industrial and commercial environments. This specific unit is designed as a versatile replacement or primary component for various audio indication needs across different electronic assemblies.

Speakers Replacement Considerations

When substituting, ensure the new speaker matches the 8 Ohm impedance and similar frequency range. Verify that the replacement can handle at least 0.25 W continuously. Physical mounting constraints must be identical due to the specific top round form factor.

Speakers FAQ

What is the lowest resonance frequency of the PSR-57F08S02-JQ?

The lowest resonance frequency (Fo) is specified as 350 Hz with a tolerance of ±20%.

Can this speaker handle continuous full-power operation?

The rated input power is 0.25 W. The maximum input power is 0.50 W, but continuous operation should generally adhere to the rated power to ensure longevity.
