PSS-20N08SM-YTRQ

Speakers Overview

The PSS-20N08SM-YTRQ is a piezoelectric speaker manufactured by Mallory Sonalert Products Inc. It features a compact form factor with dimensions of 20x20x4.5 mm and delivers a sound pressure level of 90 dB. The device operates within a frequency range of 850 Hz to 20 kHz, making it suitable for audio signal reproduction rather than simple tone generation. It is supplied in tape and reel packaging for automated surface-mount assembly processes.

Speakers Feature Summary

• Wideband frequency response from 850 Hz to 20 kHz for clear audio reproduction
• Compact 20x20 mm footprint with low profile height of 4.5 mm
• High efficiency output delivering 90 dB sound pressure level
• Designed for automated surface-mount technology (SMT) production via tape and reel

Speakers Applications

• Medical equipment audio indicators
• Industrial control panel signaling
• Consumer electronics alert systems
• Transportation vehicle status notifications

Speakers Procurement Notes

Verify the specific suffix YTRQ confirms the tape and reel packaging configuration required for your assembly line. Confirm that the 90 dB rating meets acoustic requirements at the intended operating distance. Ensure the 850 Hz lower frequency limit aligns with the target application's audio spectrum needs. Check for any RoHS or REACH compliance documentation relevant to your region.

Speakers Selection Notes

Select this component when wideband audio clarity is required instead of a single-tone alarm. The small 20x20 mm size allows integration into space-constrained enclosures. The SMT package facilitates high-volume manufacturing automation. Consider the 90 dB output against ambient noise levels to ensure audibility without excessive power consumption.

Speakers Part Context

This part belongs to the Mallory Sonalert family of audio transducers. Unlike standard buzzers that generate fixed tones, this unit functions as a speaker capable of reproducing a broader range of frequencies. It complements their industrial and medical alarm portfolio by providing voice or complex tone capabilities in a miniature form factor.

Speakers Replacement Considerations

Direct cross-references are not explicitly documented in the provided source material. Evaluate alternative speakers based on matching 20x20 mm mounting dimensions, 4.5 mm height constraints, and similar 90 dB SPL performance. Verify impedance and voltage compatibility before substituting.
