I purchased a HeaterMeter 4.3 kit from store.heatermeter.com and have a question about the Inductor. The directions say 220uH Inductor. The part says 221K and 530. (See attached photos). Do I have the correct Inductor??
Yes it is the correct inductor. The value is written in component notation, which is the first two numbers are the value and the third number is the number of zeroes. So 22 + 1x0 = 220uF. The K suffix indicates some other property but it isn't standard across components.
Another example is how the yellow 0.1uF capacitors say 104 on them, they're 10 + 4x0 = 100000pF or 0.1uF.
