NU MB ER PA RT High Current Filter Inductors Mechanical Configuration Ferrite Bobbin protected with a flame retardant polyolefin sleeve. Physical Parameters Inches Length 0.900 Max. Diameter 0.455 Max Lead Size AWG #20 TCW 0.032 ± 0.002 Lead Length 1.10 Min. 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 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.
