222K inductor?
« on: December 09, 2020, 01:55:57 am »
Hey guys im repairing a speed controller for a client as the controller is well over $1000 aud. i have found an open circuit inductor a blown resistor that links to a tny256gn ic. I plan to replace all 3 components. Would i be correct in assuming 222K stands for 2.2 mH? i have attached photo for reference.

Sounds right to me, although I am no expert.  I would guess the K means 20% tolerance.

K is 10% tolerance
M is 20% tolerance although this is rarely seen these days
