Description
EPCOS B66252B0000M001 Transformer Coil Former, 14 Pin, E55The B66252BM1 is a 14 pin GFR 6 polyamide E 55 28 21 Coil Former for use with B66252 series. Ferrite core 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
The B66252BM1 is a 14-pin GFR 6-polyamide E 55/28/21 Coil Former for use with B66252 series. Ferrite core 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
- UL94HB Flammability rating

Nice, but easily chewed apart.
My dog loves it, but needs supervision because he can bit off bits. He's a small dog with little teeth.

JAYU PET Toothbrush Toy Dog Chew
The JAYU PET Toothbrush Toy Dog Chew is pretty cool. I used my toy poodle’s favorite toothpaste and he had a hard time really getting into the grooves. This seems like a good idea and it’s hit or miss with anything like this. My dog loved it more and tried harder when I used peanut butter. I just end up having to clean o it the grooves as he can’t get to it all. Big breeds might do better, but this is cute and could work.

Highly Recommend for Aggressive Chewers!
I recently purchased the JAYU PET Toothbrush Toy Dog Chew Toy, and it has exceeded my expectations. If you’re looking for dog chew toys that are both durable and functional, this is a great choice. My dog is an aggressive chewer, and this toy has held up extremely well without breaking or wearing down.
What I love most is how it helps clean my dog’s teeth while chewing. The textured design removes plaque and tartar naturally during playtime. It’s much easier than brushing my dog’s teeth manually, and my dog actually enjoys using it.
This dog dental toy is perfect for small and medium dogs and keeps them busy for long periods, which helps reduce boredom and destructive behavior. It’s sturdy, safe, and clearly designed with dental health in mind.
Overall, this is one of the best dog chew toys I’ve purchased—durable, engaging, and great for maintaining my dog’s oral hygiene. I will definitely be buying another one!

Not for aggressive chewers
My 14 pound puppy chewed a big chunk out within 30 minutes. Would not recommend if you have a dog that likes to tear into things

Not for aggressive chewers as labeled; poor quality
Really disappointed in this item. My barely 16 lb., 1 1/2 yr old labradoodle chewed right thru the plastic in literally 6 seconds. I was going to toss it but at $18, the item should live up to its description-this toothbrush toy is rated 80% on the aggressive chew scale as per packaging…NOT AT ALL! She bit off a couple off chunks immediately, then proceeded to bite off the spikes…couldn’t believe how quickly the toy was destroyed & I took it away within moments of giving it to her.
