SPM0404HE5H-PB-6

Overview

The SPM0404HE5H-PB-6 is a mini surface-mount silicon microphone manufactured by Knowles Acoustics, distributed under the Syntiant brand. It features an analog output type and omnidirectional polar pattern with a sensitivity of -42dB ±3dB at 94dB SPL. The device operates within a supply voltage range of 1.5V to 3.6V and supports a frequency response from 100Hz to 10kHz. Its physical dimensions are 4.72mm in length, 3.76mm in width, and a maximum height of 1.35mm, utilizing solder pad termination.

Feature Summary

• Enhanced RF protection for reliable operation in high-interference environments
• Miniature surface-mount design suitable for space-constrained applications
• Analog output signal processing

Applications

• Handheld telecommunication devices
• Telecom modules
• Portable consumer electronics

Procurement Notes

Verify that the ordering suffix '-6' corresponds to the specific tape-and-reel packaging configuration provided by the distributor. Confirm that the component is sourced from Knowles Acoustics as the original manufacturer, despite the Syntiant branding on certain distribution channels. Ensure compatibility with the required operating voltage range of 1.5V to 3.6V for your specific circuit design.

Selection Notes

Select this component when enhanced radio frequency interference protection is critical for audio integrity in mobile or telecom applications. The analog output interface requires appropriate amplification and filtering stages in the signal chain. Consider the small form factor of 4.72mm x 3.76mm for integration into compact handheld devices where space optimization is a primary constraint.

Part Context

This microphone belongs to the SPM series of mini surface-mount silicon microphones designed for portable electronics. It represents a specialized variant optimized for telecommunications environments requiring robust performance against electromagnetic noise. The product line emphasizes reliability and compactness for modern mobile communication hardware.

Replacement Considerations

SPM0404HE5H-PB is the base part number without the reel suffix. Verify mechanical footprint compatibility before substituting other omnidirectional MEMS microphones with similar sensitivity ratings.
