The 2SC458 is a 30V 100mA NPN (BJT) manufactured in a plastic TO92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are from left to right the emitter, collector, and base leads.
The HW-483 is DC5V 6mm 650nm Red Color Laser Diode Module For Arduino Very Easy To Use, Do controllable laser pointer, theft detection, etc. interesting application devices.
The XL4005 is a 5A DC-DC Adjustable Step Down Module Power Supply Converter. This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module with high efficiency, low ripple and excellent line and load regulation.
The CD4040BM is ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse, a high level on the RESET line resets the counter to its all zeros stat
The FDS3890 80V 4.7A N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers.
