Planar inductor calculator

**Planar**spiral**inductors**are less expensive than either chip or coil**inductors**for PCB (printed-circui-board)-based designs. Accuracy in designing a spiral**inductor**is important because it is difficult to modify the**inductor**once you have built it on the PCB. Some formulas are available for calculating the spiral**inductor**for RF-IC applications with inductance of less than 100 nH on a single ...- Following table provides links to useful Wireless converters and
**calculators**. It include antenna gain**calculator**, Antenna G/T ratio**calculator**, coaxial cable Impedance**calculator**, Noise temperature to Noise Figure Converter, Radar Range**Calculator**, resonant frequency**calculator**, wavelength to frequency**calculator**, receiver C/N ratio, RF Budget ... - The formula for calculating the inductance of an air-core flat spiral coil is: Where. N = Number of turns. r = Coil radius in inches. l = Coil length in inches. d = Winding depth in inches. L = Inductance in microhenrys (μH) Coil dimensions for calculating inductance. Select your coil geometry, enter the dimensions, and select the units.
