Color coding of the inductance value
B82141A B82141B
The inductance value and tolerance are encoded by means of colored bands in accordance with IEC 60062. The basic unit is H. 1st band 2nd band 3rd band 4th band 1st digit of inductance value 2nd digit of inductance value multiplier, i.e. the power of ten, by which the first two digits have to be multiplied. tolerance of the inductance value.
Color code Colorless Silver Gold Black Brown Red Orange Yellow Green Blue Violet Grey White Examples:
1st band = 1st digit -- -- -- -- 1 2 3 4 5 6 7 8 9
2nd band = 2nd digit -- -- -- 0 1 2 3 4 5 6 7 8 9
3rd band = multiplier -- x 10-2 H = x 10-1 H = x 100 H = x 101 H = x 102 H = x 103 H = 0.01 H 0.1 H 1,01 H 10,01 H 100,01 H 1000,01 H
4th band = tolerance 20 % (M) 10 % (K) 5 % (J) -- 2 % (G)
x 104 H = 10000,01 H x 105 H = 100000,01 H
Special designs manufactured to customer specifications are identified by a white tolerance band.

Important notes
The following applies to all products named in this publication: 1. Some parts of this publication contain statements about the suitability of our products for certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application. As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application. 2. We also point out that in individual cases, a malfunction of passive electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of a passive electronic component could endanger human life or health (e.g. in accident prevention or life-saving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of a passive electronic component. 3. The warnings, cautions and product-specific notes must be observed. 4. In order to satisfy certain technical requirements, some of the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as "hazardous"). Useful information on this will be found in our Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed questions, please contact our sales offices. 5. We constantly strive to improve our products. Consequently, the products described in this publication may change from time to time. The same is true of the corresponding product specifications. Please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order. We also reserve the right to discontinue production and delivery of products. Consequently, we cannot guarantee that all products named in this publication will always be available. 6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of the "General Terms of Delivery for Products and Services in the Electrical Industry" published by the German Electrical and Electronics Industry Association (ZVEI). 7. The trade names EPCOS, CeraDiode, CSSP, PhaseCap, PhaseMod, SilverCap, SIFI, SIMID, SIKOREL, SIOV, SIP5D, SIP5K, TOPcap, UltraCap, WindCap are trademarks registered or pending in Europe and in other countries.
