This 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.

BC557 is a widely used PNP bipolar junction transistor manufactured in small TO-92 package. It is a general purpose PNP transistor that can be used as a switch or amplifier in electronic circuits. Its HFE ratings are 125 to 800 which makes it an ideal transistor to use as a small signal amplifier in electronic circuits for example for audio signal amplification or other, the HFE ratings of BC557 can be determined by the last letter after its number for example BC557A HFE ratings are 110-220, BC557B HFE ratings are 200-450 and BC557C HFE ratings are 420-800. The max collector dissipation is 500 milliwatt which is also an another good point to use it in amplification stages. Moreover it will also perform well when used it as a switch for load under 100mA. The transistor has also good collector to emitter (VCE) value that is -45V, therefore you can easily use it in circuits using 40 to 45 volts DC.
