are piezo buzzers & audio indicators that are an ultra-compact, lightweight, and low-profile sound producing component. These audio indicators can generate an audible sound of 85dB at 10cm. The Piezo buzzers compact size and low profile features helps make these parts ideal for using on small or precise printed circuit boards. The basics for using these parts are a power voltage connection and an external capacitor. Additionally, these components are available in a variety of voltage ranges, coil resistance values, and frequencies. These components offer high performance audio processing and are applicable for use in consumer and industrial electronics.
