SM200707-1

Overview

The SM200707-1 is a high-temperature dynamic speaker manufactured by DB Unlimited, designed for robust audio output in demanding environments. It features a nominal impedance of 7 Ohms and a power rating of 200 mW. The device operates within a frequency range of 780 Hz to 5 kHz, delivering a sound pressure level of 87 dB. Its physical construction includes a top port design with a circular shape, facilitating specific acoustic integration. The component supports panel mounting and utilizes wire leads for electrical connection. It is engineered to withstand elevated temperatures, ensuring reliable performance where standard speakers might fail.

Feature Summary

• High-temperature resistant construction for reliable operation in thermal stress conditions
• Top port acoustic design optimized for directional sound projection
• Compact circular form factor suitable for space-constrained panel installations

Applications

• Industrial control panels requiring durable audio feedback
• Automotive electronics exposed to high ambient temperatures
• Medical devices needing reliable signal indication in sterilized environments

Procurement Notes

Verify the specific temperature rating requirements against the official datasheet before procurement, as high-temperature specifications are critical for this model's intended application. Confirm that the 7 Ohm impedance aligns with the driving circuit's output capabilities to ensure optimal power transfer and prevent damage. Ensure the top port orientation matches the enclosure design for proper acoustic coupling. Check for any RoHS compliance documentation if environmental regulations apply to the final assembly. Validate the wire lead length and termination style against the available space in the target housing.

Selection Notes

Select the SM200707-1 when the application demands audio signaling in high-heat scenarios where standard components would degrade. The 200 mW rating is sufficient for clear alert tones but may not support complex audio reproduction. Consider the 7 Ohm impedance for compatibility with common driver circuits. The circular shape and top port design offer flexibility in mounting orientation compared to rectangular alternatives. Evaluate the 87 dB SPL to ensure it meets the audibility requirements of the operating environment without excessive power consumption.

Part Context

This component belongs to DB Unlimited's lineup of specialized audio transducers, focusing on durability and performance in harsh conditions. Unlike general-purpose speakers, this model emphasizes thermal stability and compact integration. It serves as a solution for industries requiring reliable audio indicators in equipment subjected to heat, vibration, or limited space. The design reflects a balance between acoustic efficiency and mechanical resilience, catering to professional and industrial markets rather than consumer entertainment.
