The formulas assume that there is NO ferrite, or brass core to the coil. Description on By setting the required inductance we get the required number of turns. YO5OFH, Csabas HAM RADIO home page - Calculating Coils For HF. Calculation of simple handmade chokes on frames of any diameter, on the cases of MLT resistors, on ferrite cores with a diameter of 2.8 mm.

I have taken two wires from the two faces of the coil and gave them to the face of the box as lumped port. I need to calculate the inductance of the coil. How to use: 1) specify the required inductance, if necessary, the diameter of an arbitrary frame 2) get the required number of turns for winding on the frame, on the cases of MLT resistors, on a ferrite rod with a diameter of 2.8 mm.Ĭoil inductors calculation program, ham radio. I have designed a coil around a ferrite rod. Description and calculation formulas can be found at in the article for the program. No additional libraries or components are needed to run it. OS: Win9x, Win2k-XP, Win7, Windows 10, and Linux. JP5587304B2 Ferrite antenna for wireless power transmission. Calculation of the coil inductance on a ferrite rod is based on the determination of the relative effective permeability of the rod. The inductor calculator presented on this page is unique in that it employs the n. GB2459269B Perpetuum Ltd An electromechanical generator for, and method of, converting mechanical vibrational energy into electrical energy. Minimum system requirements: AMD/Intel microprocessor, 5Mb of hard disk space. For 100uH you would normally use some kind of ferrite core, but the. Calculation of winding quantity is performed for choke based on: a) frame of any diameter b) MLT resistor frame c) ferrite core of 2.8 mm diameter. Designed for a wide range of radio amateurs and electronic engineers. Then the calculator estimates number of turns required and selects the smallest size bobbin core capable. The program is useful for making inductance coils in homemade radioelectronic devices: radio receivers, radio transmitters, transceivers, radio stations, antenna amplifiers and other electronic devices. The user enters target inductance and maximum operating current : the first thing the calculator does is selects a minimum wire gauge based on 700 cir-mils/Amp ( 2.8 sq.mm/A) Current Density.
