SM3604100-1

Overview

The SM3604100-1 is a high-temperature dynamic speaker manufactured by DB Unlimited. It features a round shape with a diameter of 36 mm and utilizes polyetherimide for the cone material. The component is designed for flush mount installation with solder pad termination. Key electrical parameters include an impedance of 100 ohms, a resonant frequency of 450 Hz, and a sound pressure level of 86 dBa. It has a power rating of 250 mW and operates within a temperature range of -40°C to +85°C.

Feature Summary

• High-temperature capability suitable for demanding thermal environments
• Flush mount design for integrated acoustic applications
• Polyetherimide cone material for durability

Applications

• Industrial control panels requiring high-temperature audio feedback
• Medical equipment with strict thermal operating constraints
• Automotive interior systems exposed to elevated temperatures

Procurement Notes

Verify the specific datasheet version for the SM3604100-1 to confirm current RoHS compliance status and exact dimensional tolerances. Ensure that the solder pad termination method aligns with your PCB assembly process capabilities. Cross-reference the 100-ohm impedance requirement with your amplifier output specifications to ensure proper matching and optimal performance under the stated 250 mW power rating.

Selection Notes

Select this component when a compact 36 mm round speaker is required for flush mounting in high-temperature environments up to 85°C. The 100-ohm impedance and 250 mW power handling define its electrical interface. Consider the polyetherimide cone material if long-term stability at elevated temperatures is critical compared to standard Mylar cones found in lower-rated speakers.

Part Context

This part belongs to the DB Unlimited dynamic speaker series, specifically engineered for industrial and commercial applications. The manufacturer specializes in custom acoustic solutions, and this model represents a standardized high-temperature option within their portfolio. It is distinct from general-purpose consumer speakers due to its specialized thermal rating and material composition.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing enclosures due to the specific 36 mm diameter and flush mount requirements.
