WD11903Y8H-WPDAP

Overview

The Seltech WD11903Y8H-WPDAP is a general-purpose flat speaker with an 8-ohm impedance and 500 mW power handling. It features a round shape with top porting and solder post termination. The frequency range spans from 450 Hz to 8 Hz, and it offers an efficiency of 86.5 dBA. The unit has a maximum seated height of 6.00 mm and carries an IPX7 ingress protection rating.

Feature Summary

• IPX7 water resistance for durability in wet environments
• Top ported acoustic design for directional sound projection
• Solder post termination for direct board integration

Applications

• Automotive audio systems
• Industrial equipment feedback
• Consumer electronics alerts

Procurement Notes

Verify the exact suffix WPDAP against official Seltech documentation to confirm terminal type and packaging specifications. Ensure compatibility with existing PCB footprints for solder posts. Confirm IPX7 rating requirements match the deployment environment. Cross-reference datasheet revisions for any changes in acoustic performance or physical dimensions before finalizing procurement orders.

Selection Notes

Select this component when high water resistance and compact form factor are required. The 8-ohm impedance suits standard amplifier outputs. Consider the 86.5 dBA efficiency for volume needs. Verify that the 6.00 mm height fits within the enclosure constraints. Ensure the top port orientation aligns with the desired sound direction in the final assembly.

Part Context

This model belongs to Seltech's line of high-performance flat speakers designed for automotive and industrial applications. These components utilize advanced materials to achieve robust acoustic output in constrained spaces. The series emphasizes reliability and environmental sealing, making them suitable for harsh operating conditions where traditional speakers might fail.

Replacement Considerations

Check for equivalent models with matching 8-ohm impedance and similar frequency response. Verify that replacement units support solder post termination and fit the 6.00 mm height limit. Ensure the substitute also meets IPX7 standards if moisture exposure is a concern. Confirm acoustic efficiency levels are comparable to maintain system volume consistency.
