T5 Highly Reliable Winding Toroidal Inductors Temperature
Resistance Custom Design
Toroidal inductors can be used in any inductor application that can accommodate its
shape. Although usable, toroidal inductors are not always practical
for some applications. Gapped toroidal inductors usually require
that the gap be filled with some type of insulating material to
facilitate the winding process. This is an extra expense. Powdered
cores have an effective distributed gap. These are usually
preferred over a filled gap because of lower cost and reduced gap
losses. Some printed circuit boards are space critical. Mounting a
toroidal inductor flat on the board may take up too much precious
board area. Some applications also have restricted height so the
toroidal inductor cannot be mounted vertically.
Butler Winding can make (and has made) toroidal inductors (and
transformers) in a wide variety of materials and sizes. Butler
Winding also does “bobbin wound” and “tube wound” inductors. Our
upper limits are 40 pounds of weight and 2 kilowatts of power. We
have experience with foil windings, litz wire windings, and perfect
layering. For toroids, we can (and have done) sector winding,
progressive winding, bank winding, and progressive bank winding.
Butler winding has a variety of winding machines, bobbin/tube and
toroid. That includes two programmable automated machines and a
taping machine for toroids. Butler Winding has vacuum chamber(s)
for vacuum impregnation and can also encapsulate. To ensure
quality, Butler Winding purchased two programmable automated
testing machines. Most of our production is 100% tested on these

Q: How to get samples?
A: You are welcome to get some samples before ordering. For sample,
the estimated time is 5-7 days.
Q: How to confirm the quality of products?
A: We have responsible internal QC team to check all products
before shipping. You can trust our quality is top notch. Customers
are welcome to come to check their goods before submitting final
Q: How is the customized design?
A: We are able to design wide kinds of applications based on the
client's requirements. We can proof the original design, fix the
design to meet the expectation or even design from an imagination,
and then send clients the proof for confirmation before producing.
