Operating Temperature –55°C to +125°C –55°C to +85°C @ full rated current 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.
