• Consumer electronics needing robust waterproof speakers

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct waterproofing ratings and terminal types. Confirm RoHS compliance status through manufacturer documentation prior to integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Ensure mechanical dimensions match enclosure requirements during the design phase.

Selection Notes

Select this model when high acoustic output is required in environments demanding environmental sealing. The 3-watt rating supports higher volume applications compared to standard low-power indicators. Consider the round form factor and board-mount style for space-constrained PCB designs. Evaluate the 4-ohm impedance against amplifier output capabilities for optimal efficiency.

Part Context
