## Examples Capacitor Markings Example 1:
A monolithic ceramic capacitor is marked with the legend '103K'. What is its value?
The value (in pF) will be given by the first two digits (10) followed by the number of zeros indicated by the third digit (3). The value of the capacitor is thus 10,000pF or 10nF. The final letter (K) indicates that the capacitor has a tolerance of 10% Example 2:
A circuit requires a capacitor of 47nF with a tolerance of 10%. What are its markings likely to be?
47nF is the same as 47,000pF. Thus the marking (in pF) will show the first two digits (47) followed by the number of zeros (3). Since the tolerance is 10%, the final letter should be K. Thus the marking should be '473K'. |
