Applications: LCD television set, notebook PC, portable communication equipment, DC/DC converters, etc. Operating Temperature: -30°C to +100°C (includes temp. when coil is heated) Saturation Current: This indicates the value of current when the inductance is 25% lower than its initial value at D.C. superposition or D.C. current. Temperature Current: To load current onto the components under normal ambience, which causes the temp. change as DT=40°C or more lower current. Inductance Tolerance: M = ±20%, N = ±30% Testing: Inductance is tested on an HP4285A at 100KHz, 0.25V. Packaging: Tape & Reel. Marking: Parts are marked with inductance code. Miscellaneous: RoHS Compliant. Additional Information: Additional electrical & physical information available upon request. Samples available. See website for ordering information.
