How to use: These resistors are easy to use in your electronic projects. Just connect them according to your circuit design. You can use them in things like DIY electronics, hobby projects, or even in some small repair jobs. Attention: As mentioned, the quantity of each resistor value might not be exactly 20 due to manual packing. So don't be too worried if you find a small difference. Maintenance advice: Keep these resistors in a dry and clean place. Avoid exposing them to extreme temperatures or humidity, which could affect their performance. If you're not using them for a long time, it's a good idea to store them in a sealed container.
