Using these capacitors is easy. First, check the DC voltage of your circuit. Make sure it's up to 16V because these capacitors are designed for that range. Then, connect them to your perf or breadboard using the long flexible pins. If you're dealing with low - frequency circuits (around 1KHz or less), these capacitors will do a great job on their own. But for higher - frequency circuits, you'll want to pair them with a ceramic capacitor. When handling the capacitors, be careful not to mix them up. Thanks to the clear labeling on each capacitor, it's easy to tell them apart. To maintain them, keep them in a dry and cool place. Avoid exposing them to extreme temperatures or moisture, as this can affect their performance.
