Applications: Designed for higher speed switch mode applications requiring lower inductance and high current. Next generation microprocessors, etc. Operating Temperature: -40°C to +100°C 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. Irms: To load current onto the components under normal ambience, which causes the temperature change as DT = 40°C or more lower current. Inductance Tolerance: ±20% Testing: Inductance is tested on an HP4285A at 2.0MHz. 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.
