Overview
The SMS-1508-2-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a square shape with dimensions of 15 mm in length, 15 mm in width, and 5 mm in depth. The component operates at a frequency of 850 Hz with a sound pressure level of 87 dBA. It has an impedance of 8 Ohms and a power rating of 300 mW. The unit utilizes Samarium Cobalt (SmCo) magnet material and a Mylar cone. It supports board mount installation via SMD/SMT termination types. The operating temperature range spans from -40 C to +85 C.
Feature Summary
- Square form factor designed for compact board mounting applications
- Utilizes Samarium Cobalt magnetic structure for stable performance
- Operates within extended industrial temperature ranges
Applications
- Electronic devices requiring surface-mount audio output
- Industrial equipment needing robust acoustic signaling
- Consumer electronics with limited spatial constraints
Procurement Notes
Verify the specific datasheet version for the SMS-1508-2-R to confirm RoHS compliance details and exact packaging configurations such as reel or cut tape options. Ensure that the PCB footprint matches the SMD/SMT terminal specifications provided in the official documentation. Cross-reference the thermal ratings against the final assembly environment to guarantee operation within the specified -40 C to +85 C limits without derating issues.
Selection Notes
Select this component when a square profile is required for tight spatial layouts on printed circuit boards. The 8 Ohm impedance and 300 mW rating suit low-power signal applications. Consider the Samarium Cobalt magnet if high-temperature stability is critical compared to standard ferrite alternatives. Verify that the 850 Hz resonant frequency aligns with the target acoustic output requirements for the specific device design.
Part Context
This part belongs to the SMS series of speakers from PUI Audio, Inc., which focuses on electromagnetic transducers for various electronic assemblies. The series offers different shapes and sizes to accommodate diverse mechanical constraints in modern electronic products.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Generic replacements may differ in magnetic material, impedance, or physical dimensions.
