色环电感的识别和读数
色环电感的识别和读数什么是色环电感色环电感（也称色环线圈、色环线圈电感）是一种常见的电感元件。
其外观是一根细细的导线，其中有一些具有不同颜色的环带。
这些环带通常按照一定的色码规定来设置，以便于识别其容值和误差。
色环电感的颜色和含义色环电感的颜色和含义是指电感元件上的彩色环带所代表的物理含义。
通过认识和理解色环电感的色码规则，我们可以清楚地了解到该电感元件的相关参数。
色环电感的常见色码规则如下所示：•黑色：第一位数字，代表数字 0。
•棕色：第二位数字，代表数字 1。
•红色：第三位数字，代表数字 2。
•橙色：第四位数字，代表数字 3。
•黄色：第五位数字，代表数字 4。
•绿色：第六位数字，代表数字 5。
•蓝色：第七位数字，代表数字 6。
•紫色：第八位数字，代表数字 7。
•灰色：第九位数字，代表数字 8。
•白色：第十位数字，代表数字 9。
在色码规则中，黑色环带通常代表比较小的数字，白色环带则相反。
在读取色环电感时，需要先从最多有三个环带的电感开始阅读。
例如，一个颜色为棕-黑-红的电感，它的额定值为 10 x 10^2 uH，也就是 1000 微亨。
如何读取色环电感读取色环电感需要先从最前面的环带开始，识别它的颜色，并将其对应的数字记录下来。
然后继续识别下一个带环的颜色，并将它对应的数字记录下来。
根据识别到的数字，可以得到该电感的额定值。
但是，当电感元件同时具有四个及以上的环带时，读取就变得更加复杂了。
在这种情况下，通常有两个环带代表一个数字，第一个环带表示前导数字，第二个环带表示后续数字，两者结合起来就能得到具体的数字。
例如，一个颜色为棕-黑-黑-红-棕的电感，它的额定值为 12 x 10^1 uH，也就是120 微亨。
误差和容差对于色环电感，还有两个非常重要的指标：误差和容差。
误差通常指电感元件的实际值和额定值之间的偏差，容差则是指电感元件的实际值可以偏离额定值的范围。
误差可以用百分比表示，例如，如果一个色环电感的额定值为 100 微亨，但实际上它的实际值为 102 微亨，那么它的误差就是 2%。

KG:1. General Customer ResponsibilitySome goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general suitability for certain application areas. These statements about suitability are based on our knowledge and experience of typical requirements concerning the areas, serve as general guidance and cannot be estimated as binding statements about the suitability for a customer application. The responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not.2. Customer Responsibility related to Specific, in particular Safety-Relevant ApplicationsIt has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component. Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be downloaded at .3. Best Care and AttentionAny product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.4. Customer Support for Product SpecificationsSome products within the product range may contain substances which are subject to restrictions in certain jurisdictions in order to serve specific technical requirements. Necessary information is available on request. In this case the field sales engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.5. Product R&DDue to constant product improvement product specifications may change from time to time. As a standard reporting procedure of the Product Change Notification (PCN) according to the JEDEC-Standard inform about minor and major changes. In case of further queries regarding the PCN, the field sales engineer or the internal sales person in charge should be contacted. The basic responsibility of the customer as per Section 1 and 2 remains unaffected.6. Product Life CycleDue to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of products. As a standard reporting procedure of the Product Termination Notification (PTN) according to the JEDEC-Standard we will inform at an early stage about inevitable product discontinuance. According to this we cannot guarantee that all products within our product range will always be available. Therefore it needs to be verified with the field sales engineer or the internal sales person in charge about the current product availability expectancy before or when the product for application design-in disposal is considered. The approach named above does not apply in the case of individual agreements deviating from the foregoing for customer-specific products.7.

KG:1. General Customer ResponsibilitySome goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general suitability for certain application areas. These statements about suitability are based on our knowledge and experience of typical requirements concerning the areas, serve as general guidance and cannot be estimated as binding statements about the suitability for a customer application. The responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not.2. Customer Responsibility related to Specific, in particular Safety-Relevant ApplicationsIt has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component. Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be downloaded at .3. Best Care and AttentionAny product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.4.
