Capacitor Selection Circuit Diagram Connecting a 1 µF capacitor from VIN to GND reduces the circuit sensitivity to the printed circuit board (PCB) layout, especially when long input traces or high source impedance are encountered. If greater than 1 µF of output capacitance is required, the input capacitor should be increased to match it. Input and Output Capacitor Properties Selection: Match the value specified in your circuit design. Use standard values (e.g., 10μF, 100nF) unless precision is critical. B. Voltage Rating. Definition: The maximum voltage a capacitor can withstand without breakdown. Rule of Thumb: Choose a rating ≥1.5× the circuit's operating voltage. For example, use a 25V capacitor for a 12V
Ceramic Capacitors: Application: Widely used for general-purpose coupling, decoupling, and filtering applications. Values: Available in a wide range of capacitance values, typically from picofarads (pF) to microfarads (µF). Example: Ceramic capacitors are commonly used in power supply circuits for smoothing and decoupling. Electrolytic Capacitors:

Complete List of Capacitor Selection and Formulas Circuit Diagram
Polarized capacitor; Non-polarized capacitor; The difference between a polarized capacitor and a non-polarized capacitor is that the polarized capacitor has a positive and a negative side. So it must be placed with the positive pin where the most positive voltage is. You can place the non-polarized capacitor in any way you want.
