As a type of electronic component, ceramic capacitors are made of ceramics as the main material, which has good isolation and belongs to the category of insulators. This type of capacitor is also called a disc ceramic capacitor. According to different withstand voltages, it can be divided into high-voltage ceramic capacitors and low-voltage ceramic capacitors. The main advantages of ceramic capacitors include high temperature resistance, long service life and low cost, so they have been widely used in many fields.
When it comes to the voltage resistance characteristics of ceramic capacitors, such as the 103M 1KV model ceramic capacitor, it belongs to the high voltage category. The 1KV withstand voltage referred to here refers to the DC voltage it can withstand. The characteristic of DC voltage is that its magnitude and direction remain constant in time and do not change over time. In a DC circuit, the voltage experienced by both ends of the power supply, both ends of the circuit, or both ends of the component is DC voltage. For example, the voltage across a flashlight battery and across a light bulb is a DC voltage. Due to the series-parallel configuration in electrical equipment, especially in parallel circuits, there will be a shunt current passing through each electrical load, resulting in a so-called "shunt voltage". This voltage is numerically equal to the ratio of the branch current and the branch resistance. product.
For ceramic capacitors, their withstand voltage label, no matter how high the withstand voltage value is, refers to the DC voltage it can withstand. Therefore, when it comes to high-voltage ceramic capacitors like 103M 1KV, its 1KV withstand voltage indicator actually refers to the capacitor's ability to safely operate at a DC voltage of 1KV. This is crucial for understanding the application of capacitors in circuit design, especially when dealing with DC circuits. The correct selection of capacitors with appropriate voltage levels is a key factor in ensuring safe operation of the circuit.
