In our SMT processing process, capacitors are one of the most common materials, so what is SMD capacitors?
What is a chip capacitor? A chip capacitor is a capacitor material. The full name of SMD capacitor is: multilayer (multi-layer, multi-layer) chip ceramic capacitor, also known as chip capacitor, chip capacitor. There are two ways to represent chip capacitance, one is in inches and the other is in millimeters.
What are the application characteristics of chip capacitors? First of all, the chip capacitor and the base plate are soldered with tin, and the bottom of the capacitor and the base plate are tightly bonded so that there is no gap at all. Second, there are no solder joints on the back of the board, so it will not cause a short circuit. On the other hand, chip capacitors are much higher than plug-in capacitors in terms of component and production process costs.
SMD capacitors include medium and high voltage chip capacitors and ordinary chip capacitors, and the series voltage is 63V, 10V, 16V, 25V, 50V, 100V, 200V, 500V, 1000V, 2000V, 3000V, 4000V There are two types of size notation of SMD capacitors, one is expressed in inches, and the other is expressed in millimeters. There are three types of SMD capacitor materials, NPO, X7R, Y5V NPO, which have the most stable electrical properties, almost do not change with the change of temperature, voltage and time, and are suitable for high-frequency circuits with low loss and stability requirements.
Well, that's all there is to it about chip capacitors.
