Operating Temperature –55°C to +125°C –55°C to +85°C @ full rated current Current Rating at 85°C Ambient 40°C R ise Maximum Power Dissipation at 85°C 0.7 0 W Dielectric Withstanding Voltage 2500 V R M S Incremental Current The current w hich w ill decrease the inductance by approxim ately 5%. Inductance Measurement Inductance is m easured @ 1 kH z w ith 1 VA C open circuit and 0 dc bias. Inductance Tolerance Tolerance is specified by suffixing an alpha character to the part num ber as follow s: J = 5%, K = 10%, and L =15%. U nits are norm ally supplied to the tolerance indicated in table. High Saturation Bobbin allow s for high inductance w ith low D C R . High Resistivity C ore offers very high parallel resistance, resulting in m axim um coil perform ance. 4590 Marking D E L E VA N ; inductance; tolerance. 4590R Marking D E L E VA N ; 4590R ; dash num ber w ith tolerance letter.
