Additional Details

The LVS404018-1R0T-N has an inductance of 1.0 μH with a tolerance of ±30%. The '1R0' in the part number indicates the inductance value. The saturation current is the current at which the inductance drops by a specified percentage (typically 20%). The shielded construction is achieved by winding the coil around a ferrite core and then enclosing it in a shielding material. This inductor is commonly used in switching power supplies to store energy and filter out unwanted noise. The operating temperature range is typically -40°C to +125°C. Chilisin offers a wide range of inductors with different inductance values, current ratings, and package sizes to suit various application requirements.
