[sdiy] silly inductor question

[Neil Johnson]

Roman,

(see the resistor page on my personal website)

The basic answer:

- digits 1 and 2 are the value (47)
- digit 3 is multiplier (10^digit, in this case 10^0 = 1)
- letter is tolerance (k = 10%)

So this is a 47uH 10% inductor.

Likewise, "180J" is 18uH, 5% (or 18 ohms, 5%) and "4R7" is simply 4.7
ohms.  Use the "R" instead of a decimal point which would be difficult to
notice on a small component.

Hope this helps,
Neil
