Detection of inductors 3

① Partial nH level inductors are generally indicated directly, with N or R representing the decimal point, such as 10N and 47N representing lOnH and 47nH, respectively; Both 4N7 and 4R7 represent 4.7nH, as shown in Figure 2-21. diode

② Four digit code representation (three digits and one letter), the first two digits of the three digits represent the significant digits of the inductance, and the last digit represents the number of O that should be added after the significant digits (the same as the capacitor three digit representation), in nH. If it is less than 10 nH, N or R is used to represent the decimal point, and the last letter represents the error, which is J (+50/0), K (± 10%), M (± 20%)

For example, SN6J represents 5.6nH ± 5%; 680K represents 68nH ± 10%; 473M represents 47000nH=47 dou H ± 20%.  diode
