Found inside – 6Procedures for designing filter inductors using air gapped cores are. Examples of nonmagnetic materials are air, wood, copper, plastic, and . Inductance values are calculated to 3 decimal places and are given in nH, µH, mH and even to 5 decimal places, H! Found inside – Core Material As discussed earlier, an inductor is basically a coil of wire. This calculator is useful when making antenna matching units, low pass filters, crystal sets, antenna traps, resonant circuits or anywhere where an air cored single layer inductor is required. Found insideThis book takes you inside wireless technology with step-by-step, illustrated directions for dozens of usable projects. Follow, © Copyright 2020, All Rights Reserved 2012-2020 by. Diameter and length of inductor are entered in millimetres along with the number of turns. The air core coil with an inductor does not depend upon a ferromagnetic material to achieve its specified inductance. So it appears the thinnest traces (0.1mm) with 70 turns is actually preferable.Seventy six + = 79.

I appears that the inductance / resistance ratio is

My maximum diameter is 30mm so by varying the trace width I can choose from the following optionsĠ.1mm trace width, 70 turns, inductance = 47uH and 1.55ohms resistance.Ġ.2mm trace width, 45 turns, inductance= 20uH and 0.48ohms resistance.Ġ.3mm trace width, 35 turns, inductance= 12uH and 0.25ohms resistance.Ġ.4mm trace width, 28 turns, inductance = 7.6uH and 0.15 ohms resistance. I found this trace calculator which lets me estimate the resistance. Is there any way to estimate the given the expected resistance? My copper is only 35um per side (2oz/CuFt) which means the resistance is substantially higher than the wire diameter suggests. I’m also using this excellent Kicad footprint wizard ( ) So being able to try out parameters before ordering the boards is incredibly useful. I’m making this on FPC (flex pcb), 2 layers. Thank you for making such a fantastic website! I’ve just noticed that the calculator also allows me to enter the coupling capacitance.
