Learn how to choose the right components for a circuit design based on function, performance, cost, reliability, and compatibility. Find tips and guidelines for circuit design and component selection.

Electrical circuits can be classified into three main types: series, parallel, and combination circuits. In a series circuit, components are connected end-to-end, with the current flowing through them ...

The first step to identify which components to test is to understand the circuit diagram. A circuit diagram is a graphical representation of the connections and functions of the components in a ...

The Circuit. The components shown here have higher ratings than are strictly needed—I prefer to play it safe. Capacitor C1 reduces the high voltage AC—this component must be rated 400V AC. Resistor R1 ...

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space a… ...

Dealing with passive components. Obviously, active circuits can contribute to EMI problems, but what about simple passive devices? They may not actual cause EMI problems, but if poorly selected or ...
