SP-4009Y

Overview

The SP-4009Y is a general-purpose dynamic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a maximum power handling capacity of 1 watt, with some sources indicating up to 1.5 watts. The device operates within a frequency range of 600 Hz to 12 kHz, with a self-resonant frequency of 600 Hz. It delivers a sound pressure level of 88 dBA when tested at 100 mW/100 mm. The physical dimensions are 40.00 mm in length and 20.00 mm in width, utilizing a rectangular form factor with top port location and solder eyelet termination.

Feature Summary

• Rectangular magnetic technology design for general audio applications
• Top port location configuration for directional sound output
• Solder eyelet termination method for secure circuit integration

Applications

• Embedded systems requiring compact audio feedback
• Industrial automation equipment signaling
• General purpose electronic devices needing simple sound reproduction

Procurement Notes

Verify the specific manufacturer datasheet for exact electrical tolerances and mechanical drawings before integration. Confirm that the solder eyelet termination matches your PCB layout requirements. Ensure the operating environment does not exceed the thermal limits associated with the 1-watt power rating. Cross-reference the active part status with current supply chain availability to prevent production delays.

Selection Notes

Choose this component when a low-cost, rectangular speaker with top-firing sound projection is required. The 8-ohm impedance suits standard amplifier outputs without complex matching networks. Consider the 88 dBA sensitivity for applications needing moderate volume levels. The fixed frequency response limits suitability for high-fidelity music but supports voice or alert tones effectively.

Part Context

This model belongs to the SP Micro Speaker series from Soberton Inc., which focuses on compact dynamic speakers. The series typically utilizes magnetic technology for efficient sound generation in small footprints. The SP-4009Y represents a standard general-purpose variant within this lineup, designed for cost-effective mass production in consumer and industrial electronics.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with any alternative components by matching impedance, sensitivity, and physical mounting dimensions.
