The ferrites offered here provide excellent suppression of energy from a broadband pulse, like that of an EMP. Select a size that will clip around your cable -- too large is okay, but not too small. Looping the cable through the ferrite helps to further reduce the transient, see video below.
Ferrites are ceramic compounds that consist of a mixed oxide of iron and one or more other metals. They have long been used to protect sensitive electronic equipment from conductive transients. Ferrites offer a simple, but effective, way of protecting items that must remain plugged in, such assolar panels, charge controllers, generators, computers, or amateur radios. They can even be used on some automobile wiring.They are very simple to use. Simply click them around the cable feeding the sensitive item. Thats it!
Clip-on broadband ferrites are often used to protect small appliances and electronics (e.g., computers, TVs, etc.). They simply clip around the power cord. They can also be used on solar power generation wires and other applications where ease of application is desired.
When to use high-saturation ferrites?
Clip-on high-saturation ferrites are used in four scenarios:
1. High current is flowing through the wires, and you cant easily get to the ends of the wires to feed them through a toroid.
2. High current is flowing through the wires, and a clip-on broadband ferrite is not large enough to go around the wire bundle.
3. There is not enough space to fit a large toroid.
4. The application is such that a solid, non-hinging, ferrite is preferred.
High-saturation ferrites are available for the whole-house (Whole-house Ferrite Link) and automobiles (Automobile Ferrite Link).
When to use toroid ferrites?
Toroid ferrites are great to use when you can feed the wire bundle through the ferrite. A good example is when trying to protect solar power generation system batteries. Simply disconnect the leads from the battery, feed through the toroid and reattach the leads to the battery (Toroid Ferrite Link).
How to install ferrites?
Broadband ferrites clip around wire bundles.
High-saturation ferrites clip around individual high-current wires.
Toroid ferrites are placed around wire bundles by feeding the wires through.
