Inductance Measurement
Inductance is measured
@ 1KHz with 1 VAC open circuit and 0 dc bias.
Inductance Tolerance
Tolerance is specified by
suffixing an alpha character to the part number as
follows: J = 5%, K = 10%, and L = 15%. Units are
normally supplied to the tolerance indicated in table.
Marking
Parts are printed with DELEVAN,
Inductance Value and Tolerance.
High Saturation Bobbin
allows for high inductance
with low DCR.
High Resistivity
Core offers very high parallel
resistance, resulting in maximum coil performance.
Packaging
