AL: Inductance produced as a function of the
number of coil turns. AL is uH/100 turns for iron-powder cores, and mH/1000
turns for ferrite cores.
frequency range: Frequencies over which the
core material is designed to be used
mH: Abbreviation for millihenry
microhenry: One millionth of a henry, a measure
of inductance. Abbreviated "uH"
millihenry: One thousandth of a henry, a measure of inductance. Abbreviated
Q: "Quality factor" - Inductive reactance divided
by resistance: Q = XL/R
turn: One wire winding on a core. Each pass of the wire
through the center of a core counts as one turn.
u: Electromagnetic permeability of a core. Cores with higher
u values produce higher inductance. Pronounced 'mu' (the name of the Greek letter).
uH: Abbreviation for microhenry
