Description
EPCOS B66422W1010D001 Transformer Coil Former, 10 Pin, EFD25The B66422W1010D001 is a 10 pin GFR Thermosetting Plastic EFD 25 13 9 Coil Former for use with B66421 series. Ferrite cores have to meet mechanical requirements during assembling and for a growing number of applications. Since ferrites are ceramic materials one has to be aware of the special behaviour under mechanical load. As valid for any ceramic material, ferrite cores are brittle and sensitive to any shock, fast changing or tensile load.
The B66422W1010D001 is a 10-pin GFR Thermosetting Plastic EFD 25/13/9 Coil Former for use with B66421 series. Ferrite cores have to meet mechanical requirements during assembling and for a growing number of applications. Since ferrites are ceramic materials one has to be aware of the special behaviour under mechanical load. As valid for any ceramic material, ferrite cores are brittle and sensitive to any shock, fast changing or tensile load. Especially high cooling rates under ultrasonic cleaning and high static or cyclic loads can cause cracks or failure of the ferrite cores. Stresses in the core affect not only the mechanical but also the magnetic properties. It is apparent that the initial permeability is dependent on the stress state of the core. The higher the stresses are in the core, the lower is the value for the initial permeability. Thus the embedding medium should have the greatest possible elasticity.
- Ferrites can run hot during operation at higher flux densities and higher frequencies
- The magnetic properties of NiZn-materials can change irreversible in high magnetic fields
- UL94V-0 Flammability rating

Size matters to my Chihuahua 😂
Color: Black+Grey
Finally, 4th times the charm, I bought similar remotes from 3 other Amazon listings and they were all 1/2 inch bigger than in the photos or description, and from one's I bought for my Chihuahua last year, he wouldn't touch them! As soon as I gave these to him, he quickly grabbed them and started playing with them. They're about the same size as a real fire stick, which is his obsession. Will buy more to stock up for him!

Sturdy rope
Size: Medium (23.60")
Very sturdy rope. My dog is a heavy chewer and this rope is perfect for her.

This is the one for my dog, (and maybe yours)
Size: Medium (23.60")
Great dog toy! Got the larger size— less accidental hand bites that way. It’s our second one, but the pup is a strong chewer so no disappointments with the product at all. Many breeds would not do what mine did to the rope. I love that it’s natural cotton. The longer version that I ordered comes with 3 knots, including one near each end— great— and one in the middle, which I don’t like or need. It’s a tad difficult to untie the central knot, but it’s possible with a screw driver or awl, and then it’s a perfect toy.

Does not fray.
Size: Medium (23.60")
My 70# poodle loves playing with it. She throws it in the air and catches it and brings it to me and I throw it or I tug with her. It’s very sturdy.

Rope chew
Size: Medium (23.60")
It’s perfect for an over aggressive dog chewer, especially a puppy has worked phenomenally. Well he has not chewed through it, which is amazing. We’ll get it again, but a bigger one as he grows.
