The 2SC828 is an NPN, Silicon-based AF Amplifier Transistor that is mainly used in AF based audio equipment for amplification and switching. It has a Collector-Emitter Voltage of 25 Vdc with a Collector-Base voltage of 25 Vdc.
The S8550 is a PNP Epitaxial Silicon Transistor. 40V 500mA 2W Output Amplifier of Portable Radios in Class B Push-pull Operation. Complimentary to SS8050.
The HW586 is maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above to achieve 10Ah XX.XX, and so on.
The CD4093BM is consists of four Schmitt-trigger circuits. Each circuit functions as a two-input NAND gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive- and negative-going signals.
