- This is a small Buzzer, which can be mount on PCB. It has two pins; the bigger pin should be connected to positive supply and shorter one should be connected to ground connection. Operating voltage range is 5-12V. If you provide provide square wave of 5V, it will create a good sound. for a optimum sound quality provide 2-4KHz wave.

A lithium-ion battery or Li-ion battery is a type of rechargeable battery. Lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications.
Crystal Oscillator 8 MHZ
₹8.20Add to cartThis is a 8MHZ Crystal. This is a low cost crystal oscillator with oscillation frequency of 8Mhz. Crystal are normally required to provide clock pulses to your micro controller or other IC’s which require external clock source.
An oscillator crystal has two electrically conductive plates, with a slice or tuning fork of quartz crystal sandwiched between them. The crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. Quartz has the further advantage that its elastic constants and its size change in such a way that the frequency dependence on temperature can be very low.
