† The complete Dash Number will include two additional letters (indicated by **). The first additional letter (J = 5%, K = 10%, L = 20%) will
indicate the inductance tolerance and the second additional letter will indicate the failure rate symbol (e.g., M, P, R, S) and will be added to the
end of the Dash Number. *The Rated DC Current is based on + 90°C ambient temperature with a 35°C rise.
