Buzzer element products, also known as “benders,” are composed of two conductive electrodes sandwiching a piezoelectric material, which exhibits a mechanical deflection when subject to an electric field; or conversely produces an electrical signal when subject to mechanical strain. Products of this type are primarily used to form compact audio signaling devices, often by attachment to the wall of a device’s enclosure, which aids transmission of the vibrations produced by applying an electrical signal to the buzzer element into the surrounding air.
Frequency: The frequency the device is designed to operate at
Voltage - Input (Max): Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Type: The type of device being offered.
Impedance: The device’s impedance value.
Capacitance @ Frequency: Characterizes the amount of capacitance between the device terminals, measured at the test frequency indicated.
Operating temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Size / Dimension: The physical dimensions of the device, typically given as Diameter in Inches (Millimeters)
Termination: The style of the terminations used to connect the device to the system, such as Solder Pads or Wire Leads.
