Power Inductors - Unshielded CT814AYF Series From 10 µH to 1500 µH Not shown at actual size. RoHS Compliant CHARACTERISTICS Description: SMD (unshielded) power inductor Applications: LCD televisions, PC notebooks, portable communication equipment, DC/DC converters, etc. Operating Temperature: -30°C to +100°C Inductance Tolerance: ±10%, ±20% Saturation Current: This indicates the value of current when the inductance is 10% lower than it’s initial value at D.C. superposition or D.C. current. Temperature Current: To load current onto the components under normal ambience, which cause the temp., change as Δt=40°C or more lower current. Testing: Inductance is tested on an HP4285A at 100 kHz, 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. ctparts.com SPECIFICATIONS Part numbers are marked to indicate tolerance available. K = ±10%, M = ±20% Part Number Inductance (µH) L Test Freq. (kHz) DCR Max.
