Overview
The SM200508-1 is a round dynamic speaker manufactured by DB Unlimited. It features an 8-ohm impedance and a nominal power rating of 500 mW. The unit has a diameter of 20 mm and operates within a frequency range of 500 Hz to 10 kHz. It delivers a sound pressure level of 94 dBA at 10 cm. The cone material is Mylar, and it utilizes solder eyelets for termination. The device supports flush mounting and functions between -20°C and +60°C.
Feature Summary
- IP54 rated enclosure providing protection against dust ingress and water splashes from any direction.
- Compact round design with flush mount installation style suitable for space-constrained applications.
- Mylar cone construction paired with solder eyelet termination for reliable electrical connection.
Applications
- General purpose audio output in compact electronic devices
- Industrial control panels requiring environmental resistance
- Medical equipment housings needing sealed audio components
Procurement Notes
Verify the specific suffix or revision code on the component marking against the official DB Unlimited datasheet to ensure compatibility with your circuit requirements. Confirm that the IP54 rating meets the environmental exposure standards of your final assembly location before integration.
Selection Notes
Select this model when a small form factor (20 mm) is required alongside basic environmental sealing. The 8-ohm impedance matches standard low-voltage amplifier outputs. Ensure the available 500 mW power handling aligns with the signal levels generated by the driving electronics to prevent thermal damage.
