Examples: Inductor Markings<^< Inductor Markings | Course Index | Inductor Symbols >^> Example 1:
A ferrite cored inductor is marked with the legend '471K'. What is its value?
The value (in µH) will be given by the first two digits (47) followed by the number of zeros indicated by the third digit (1). The value of the inductor is thus 470µH. The final letter (K) indicates that the inductor has a tolerance of 10%. Example 2:
A circuit requires an inductor of 68µH with a tolerance of 5%. What is it likely to be marked?
The marking (in µH) will show the first two digits (68) followed by the number of zeros (0). Since the tolerance is 5%, the final letter should be J. Thus the marking should be '680J'. <^< Inductor Markings | Course index | Inductor Symbols >^> |
