inductor design

An automatically tuned 7-30MHz mobile antenna - This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.

CWS Coil Winding Specialist - Manufacturer of transformers, inductors coils and chokes. Custom winding, EMI / RFI Filters, Antenna Windings on ferrite rod, Antenna Winding on phenolic. Any antenna coil designs.

Communication Coil - Communication Coil, Inc. designs and produces custom, high reliability Filter Networks, RF Coils, Chokes, Inductors, Baluns, Toroids and Power Magnetics for communications

PExprt - Tool for magnetic component design and modeling. Design and modeling of magnetic components such as inductors, planar transformers and integrated magnetics used in power-electronics applications.

LCLAYOUT drawing software - Simple inexpensive program that allows L-C filters designed by PCFILT or S/FILSYN which are to be built using air wound inductors and single layer capacitors cut from alumina or duroid substrate materials

Inductor Design Software - RF toroid - A free too designed to assist in the selection of iron and alloy powder cores. RF toroid calculate the location of the Self resonate frequencies for series and shunt inductors.

LC Filter Design - This is an interactive design package for designing analogue (i.e. hardware) filters made of inductors and capacitors (Ls and Cs).

Toroid Pro - Designed by microwave engineers to provide filter, radio,microwave and Ham radio engineers with all relevant information of an inductor and core at his or her finger tips
