What made you select MRC Components Nanocrystalline Filtercores as a product to feature?
When I was a child growing up in Sigmaringen, Germany, I remember being in the kitchen with my mother baking cakes. There was a small radio that played music. The oven was a gas stove, there was no microwave or other electrical appliances in the kitchen. As soon as my mother started the mixer for the cake batter, I heard the hum on the radio…
Today we have a variety of electrical appliances in the kitchen and, thanks to interference filters in each appliance, we no longer hear a hum on the radio when a mixer starts. Without such filters, the devices would turn on by themselves due to electromagnetic waves.
Compared to other filter cores, nanocrystalline MRC filter cores have very low loss (1000times lower than SiFe), have a high saturation induction (1,2T), are broadband (large frequency range) and can have very high inductances (100.000µi @10kHz), which makes the filter very small. Filter core sizes: OD ca. 7mm to 120mm (possibilities from ca. 3mm to about 500mm).
What are the key features and specifications of MRC Components Nanocrystalline Filtercores?
