Sonitron SMB Piezo Buzzers

Sonitron SMB Piezo BuzzersSMB piezo buzzers are multitune acoustic generators allowing for changing sound frequency by connecting additional capacity. Piezo buzzers have a built-in CMOS-generator powered from direct-current voltage source.All piezo buzzer models available in this series have a number of peak frequencies generating signals with the frequency from 2,500 to 100 hertz.They consume little current from 100 microamperes to 4.8 microamperes at the operating voltage of 15 Volts. The lesser operating frequency is, the lesser consumed current will be.To operate this buzzer at various frequencies, just connect the external capacitor between the grounding point and the control lead. If you connect a resistor with the rated resistance of 47 kilo Ohms, the piezo buzzer will not operate.SMB-17 piezo buzzers have dimensions as follows: 18.6 х 18.6 mm, while SMB-32 piezo buzzers have such dimensions as 33.5 х 33.5 mm.SMB piezo buzzers come in already assembled design or in surface-mounting package.SMB piezo buzzers offer a number of benefits such as low price, solid case, no electromagnetic noise, low power consumption, small dimensions and case width. Besides, they are extremely easy to operate and can be mounted both on the board or control panels.Piezo buzzers find wide utility in cars, office equipment, telephony, electronic toys, watches, alarm systems, instrumentation, and medical equipment.
