SM160816-1

Overview

The DB Unlimited SM160816-1 is a general-purpose dynamic speaker featuring a 16 mm diameter and 2.55 mm height. It operates with an impedance of 16 Ohms and a rated power of 300 mW, with a maximum power handling of 600 mW. The device utilizes a Polyethylene Naphthalate (PEN) cone material and offers a sound pressure level of 85 dB. Its frequency response spans from 880 Hz to 20 kHz, with a self-resonant frequency of 880 Hz. The unit employs top porting for acoustic output and uses solder pad termination for electrical connection.

Feature Summary

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact dimensional tolerances before finalizing design integration. Ensure that the selected mounting method accommodates the 16 mm diameter and 2.55 mm profile constraints. Confirm that the circuitry can drive the 16 Ohm impedance load at the required 300 mW power level without distortion.

Selection Notes

Select this component when a compact form factor with a 16 mm diameter is required for space-constrained designs. The 16 Ohm impedance suits specific amplifier outputs, while the PEN cone material offers durability. Consider the 85 dB SPL rating against ambient noise requirements and verify that the 880 Hz to 20 kHz frequency range meets the intended audio fidelity standards.
