Sep 19, 2009· Here''s a Large Toroid Inductor-The Electronic Goldmine but it''s probably only good for 8-10A. It would be tedious, but you can get 2x the current rating by removing the wire and rewinding the same wire as a pair (bifiliar). This Ferrite Core 10uH Inductor-The Electronic Goldmine should be good. Don''t worry too much that they aren''t sure how ...

Iron powder has been used as a core material in RF circuits for many years. It is typically used to produce high "Q" inductors from 50KHz to 500MHz and broadband transformers above 50MHz.
Sep 04, 2012· Build your own HF balun A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cables. Many hams connect the center conductor of the coaxial cable to one side of the dipole, and the shield to the other.
Jul 28, 2008· Like most things in my life Sarge, I can''t take credit for the soup ladles. Saw it on the internet,, but yeah, get 4 matching ones at the dollar store or wherever and bend the handles at 90 degrees. Surprised myself when I found a blower motor on a non-AC van that I never robbed but alas, it seems to have too much stiction. 1350 rpm with a drill motor did 6.5v and it seemed very sensitive to ...
Oct 17, 2006· The toroid measures a bit less than 1 inch OD but definitely more than 0.94". I don''t have a set of calipers here but it looks to be about 0.97" based on the ruler I have. The ID is about 0.50 inches. The thickness is about 0.34". These dimensions don''t seem to be standard. By the way, here is the listing for these toroids:

Iron powder has been used as a core material in RF circuits for many years. It is typically used to produce high "Q" inductors from 50KHz to 500MHz and broadband transformers above 50MHz.
Nov 28, 2010· These toroids have an Al value of 9900. 44 turns of AWG 20 magnet wire (about 1.5 yards, 4.5 feet or 54", make sure to use some extra), or will nearly fill the toroid, and have an approximate inductance of 20uH.
Due to the superior magnetic properties of Toroidal transformers they will be susceptible to high magnetizing current when initially energized, only limited by the low DC resistance of the primary winding.
Regarding winding toroid coils: the best core I have found so far is part # G6683 from Electronic Goldmine (5 for $1.00). 5 turns on one of these is all you need for L1. They are real easy to wind. I''ve wound them with #14, #16, #20 and #24 enameled wire and many different kinds of insulated wire, and every one works.

Toroidal Transformers - Tortech''s Toroidal transformers meet modern day requirements for a smaller size, low magnetic interference field transformer. Small size and weight (approximately 50% of conventional transformers), extremely low in noise and low stray magnetic field make the toroidal transformer ideal for compact power supplies. If our stock Toroidal.
Finding the magnetic field inside a toroid is a good example of the power of Ampere''s law. The current enclosed by the dashed line is just the number of loops times the current in each loop. Amperes law then gives the magnetic field by . The toroid is a useful device .

Jul 10, 2010· Speaking of which, I just ran some tests on that 5-pack of toroids I received from Electronic Goldmine: G6683 The Al value is around 10,000, which is quite high. 10 turns gave me 936uH; 20 turns were 4mH. They would be good for low-frequency stuff, .
Toroid . Picture of a toroid. A toroid is a solenoid that wraps around on itself. toroid: A donut shaped inductor where the magnetic fields stay contained within it. Has an air gap. A Toroid is a doughnut-shaped object enclosed by a torus. It has a ring-shaped surface generated by rotating a circle around an axis that does not intersect the circle.
