Inductor Color Code - Ex. 270μH ± 5%
 
			  
			  - First find the tolerance band, it will typically be gold (5%) and sometimes silver (10%).
 
			  - Starting from the other end, identify the first band - write down the number associated with that color; in this case Red is 2.
 
			  - Now 'read' the next color, here it is Violet so write down a 7 next to the two. (you should have '27' so far.)
 
			  - Now read the third or 'multiplier' band and write down that number of 10.
 
			  - In this example, the 'multiplier' band is Brown so we get 270 μH.
 
			  - If the 'multiplier' band is Gold move the decimal point one to the left.
 
			  - If the 'multiplier' band is Silver move the decimal point two places to the left.
