E01 stands for chip capacitor. Chip capacitor is a kind of capacitor in surface mount technology, which is widely used in electronic products. It has the advantages of being small, reliable, stable and easy to assemble, so it is widely used in electronic systems. Its main application areas include communications, computers, consumer electronics, automotive electronics, industrial control and so on. E01 chip capacitor size is small, often used in various circuits, such as limiter circuit, filter circuit, voltage regulator circuit, etc., with high capacity, high precision, good frequency response characteristics, suitable for high capacitance accuracy requirements of the circuit.
