Some samples of toroids we have manufactured.
Have you considered using a toroid in your application?
Some types of toroidal components that can be manufactured are:
| Current Transformers |
Power Transformers |
| Isolation Transformers |
Inductors |
| Pulse Transformers |
Saturable Reactor |
| Switching Power Supply Transformer |
High-Q Tuning Inductor |
| Common Mode Chokes |
Surface Mounts |
We use a variety of core materials for designing our toroids. A few of the types
are:
| 1) Wound metal-tape without Nickel typically for lower frequency
(less than 1kHz). |
| 2) Wound metal-tape with high Nickel content typically for higher
frequency (greater than 1kHz). |
| 3) Ferrite mixes for any given permeability, frequency and/or B-H
curve. |
| 4) Powdered Iron for hign-flux apllications. |
We have the capability to manufacture toroids from 1/16" I.D. to 28" O.D.,
with wire size up to 6 AWG.
Often, a transformer or inductor designed on a laminated or cut-core, will
perform much better when a toroidal core is chosen. For our engineering department
to select the correct material and size of toroid we will need to following data:
1)
Frequency and waveshape of operation. |
2) DC
bias, if applicable. |
3) AC
voltage and/or current during operation. |
4)
Required inductance for the application. |
5) Use of
component, ie. common-mode choke, saturable reactor, switching power supply transformer,
high-Q tuning inductor, pulse transformer, power transformer, etc. |
6) VA
(power) required. |
7)
Physical Size constraints. |
8)
Mounting requirements. |
9)
Terminations, ie. lugs, leads, screw terminals. |
10) Maximum
allowable temperature rise. |
11) Regulation,
if applicable (no load to full load) |
12) Case style
requirements, if applicable. |
