Current Rating at 85°C Ambient 40°C Rise
Maximum Power Dissipation at 85°C 0.70 W
Dielectric Withstanding Voltage 2500 V RMS
Incremental Current The current which will decrease the
inductance by approximately 5%.
Inductance Measurement Inductance is measured @ 1 kHz
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.
High Saturation Bobbin allows for high inductance
with low DCR.
High Resistivity Core offers very high parallel resistance,
resulting in maximum coil performance.
4590 Marking DELEVAN; inductance; tolerance.
4590R Marking DELEVAN; 4590R; dash number with
tolerance letter.
