Capacitors belong to the category of passive components. When buying a capacitor, you will usually buy as much capacitor as you need. Those who have purchased capacitors generally know that there is an error range for capacitors. This is not the error range of size, but The capacitance error range, and the closer to the capacitance value range, the more expensive. What is the significance of the capacitance error range? In fact, in many industries, many products have error range values. For example, the error range value of some zero components may be his size, because it is now a streamlined operation, and it is not 100% guaranteed that each product parameter is exactly the same. , In order to specify a certain standard, there is an error range, and the error range of a capacitor is generally called tolerance. The more common capacitance tolerance is ±5%/±10%/±20% in percentage. There are some more accurate ones like ±0.5%/±1%/±2%, it just depends on what product is used. For example, if it is a very precise instrument and equipment that does not allow any deviation, it may use a capacitor with a more accurate tolerance range. Don't imagine the accuracy of the capacitance tolerance range is well controlled. It can only control the capacity error range. Within the standard, if you want to more accurately control the tolerance range, then in the mechanical equipment, the selection of raw materials, and the operation of experience are all indispensable. The most common is to produce tens of thousands of capacitors. Only a few thousand capacitors with high precision capacitance range can be found inside, so the price is very expensive. Generally, the larger the tolerance range, the more favorable the price. On the contrary, the more expensive. Therefore, the general purchase of capacitors is acceptable within the capacity range. If you are too deliberately faulty, then the expensive cost will naturally only be transferred to consumers. Under popularization here, generally high-precision tolerance capacitors are generally used in military industry. /Aerospace/Transportation, etc. There are only a few civilian products. This is the meaning of the capacitance error range of the capacitor. I hope it can help you.
