BR1511L035UN6-WP

Overview

The Seltech BR1511L035UN6-WP is a rectangular dynamic speaker with top porting, designed for compact audio applications. It features a Polyetheretherketone (PEEK) cone and an Nd-Fe-B magnet. The unit measures 15x11x3.5 mm and offers a rated power of 700 mW with a maximum power handling of 1.2 W. Key electrical parameters include a nominal impedance of 6 Ohms, a sensitivity of 72 dB, and a resonant frequency (F0) of 900 Hz. The frequency response spans from 475 Hz to 20,000 Hz, with a total Q factor (Qts) of 0.031.

Feature Summary

• Waterproof construction certified to IPx7 standard
• Rectangular form factor with top port location
• Polyetheretherketone (PEEK) diaphragm material

Applications

• Handheld devices
• Intercom systems
• Compact medical equipment
• Wearable technology

Procurement Notes

Verify the specific suffix -WP confirms the waterproof IPx7 rating and solder pad termination style. Confirm the exact dimensional tolerance and acoustic performance metrics against the official datasheet before integration. Ensure compatibility with the target enclosure design regarding the top port orientation.

Selection Notes

Select this component when a small footprint and water resistance are required. The high F0 of 900 Hz indicates suitability for higher-frequency reproduction rather than deep bass. Consider the 6 Ohm impedance for amplifier matching. Evaluate the PEEK cone properties for durability in harsh environments.

Part Context

This model belongs to the Seltech BR series of miniature speakers. The -WP suffix denotes a waterproof variant with solder pads, distinct from the standard BR1511L035UN6 which lacks the IPx7 certification. Add-on models like BR1511L035UN6WPDAW include adhesive and wires.

Replacement Considerations

The non-waterproof BR1511L035UN6 is a direct mechanical substitute but lacks IPx7 protection. For different impedances, consider the CR1511L035UN8GDA (8 Ohm). Verify acoustic center and mounting hole patterns when substituting.
