Overview
The SM150908-2 is a dynamic speaker manufactured by DB Unlimited. It features a round shape with a 15 mm diameter and a Mylar cone material. The component has an impedance of 8 Ohms and a power rating of 500 mW. Its sound pressure level is 85 dBA, and the resonant frequency is 920 Hz. The operating temperature range spans from -30 C to +70 C. The unit is designed for flush mounting and has a height of 2.9 mm.
Feature Summary
- Flush mount design suitable for compact enclosures
- Mylar cone construction for dynamic audio output
- Operates within a wide temperature range
Applications
- Electronic devices requiring small form factor audio
- Industrial equipment needing robust environmental tolerance
- Consumer electronics with limited internal space
Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance details and exact packaging quantities. Ensure the application environment stays within the specified -30 C to +70 C operating temperature range. Confirm that the 8 Ohm impedance matches the driving circuit requirements. Check for any specific mounting hole dimensions required for the flush mount configuration.
Selection Notes
Select this component when a low-profile, round dynamic speaker is required. The 15 mm diameter fits tight spaces. The 8 Ohm impedance is standard for many driver circuits. Consider the 500 mW power handling for volume needs. The Mylar cone offers a balance of cost and performance for general purpose audio.
Part Context
DB Unlimited specializes in miniature speakers and transducers. The SM150908-2 belongs to their line of dynamic speakers designed for integration into various electronic assemblies. This series focuses on providing reliable audio solutions in compact physical dimensions.
Replacement Considerations
Check for other DB Unlimited models with similar 15 mm diameter and 8 Ohm impedance. Verify mechanical fit for flush mounting. Ensure electrical parameters like impedance and power rating are compatible with the existing circuit design before substitution.
