Speakers Procurement Notes

Verify the specific datasheet version for the PHUA6630-076B-00-000 model to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with driving circuits capable of handling the specified 24Vp-p peak-to-peak voltage. Confirm that the flex contact termination method aligns with the target PCB assembly process. Check for any RoHS or environmental compliance certifications required for the specific deployment region.

Speakers Selection Notes

Select this component when a thin-profile, high-capacitance piezoelectric speaker is required for general-purpose audio tasks. The 2.2 Ohm impedance and 8.2 µF capacitance dictate specific driver requirements compared to lower capacitance alternatives. Consider the 100 Hz to 20 kHz frequency response for voice or tone applications rather than high-fidelity music. The rectangular shape and FPC termination suit space-constrained designs requiring direct board mounting.

Speakers Part Context

This part belongs to TDK's PiezoListen series, which focuses on piezoelectric actuators and speakers. The PHUA prefix indicates the product family, while the numeric suffixes define the physical dimensions and electrical characteristics. This specific model represents a larger format variant compared to smaller piezo elements, offering higher power handling capabilities suitable for audible alerting in consumer electronics.

Speakers Replacement Considerations

Cross-reference with other PHUA series models for dimensional fit. Verify if alternative piezo speakers with similar 2.2 Ohm impedance and comparable capacitance values meet the acoustic requirements. Ensure replacement parts support the same flex contact termination style to maintain assembly compatibility.
