Applications: Power supplies for VTR, OA equipment, LCD televisions, PC notebooks, portable communication equipment, DC/DC converters, etc. Operating Temperature: -40°C to +125°C Inductance Tolerance: ±20%, ±30% Testing: Inductance is tested on an HP4284A at specified frequency. Irms: To load current onto the components under normal ambience, which cause the temperature change as ΔT=40°C or more lower current. Isat: This indicates the value of current when the inductance is 25% lower than its initial value at D.C. superposition or D.C. current. Packaging: Tape & Reel. Marking: Parts are marked with inductance code. Miscellaneous: RoHS Compliant. Magnetically shielded. Additional Information: Additional electrical & physical information available upon request. Samples available. See website for ordering information. Size A mm inches 12.5 8.0 7.6±0.2 5±0.2 0.492 0.314 0.3±0.007 0.2±0.007 B C B(max.) A(max.) XXX D D A(max.)
