Material Information

43&4A3 Material: The material is used for EMI/RFI suppression in the 20 MHz to 250 MHz range
52 Material: The Material which is made of a new NiZn Ferrite material, combines a high saturation flux density and a high Curie temperature.It is used for EMI/RFI suppression in the 200 MHz to 1 GHz range.
61 Material: The material is designed for inductive applications up to 25mhz and also suppresses noise frequencies from 200MHz to 1000 MHz.
67 Material: The Material is for high Q inductors up to 50 MHz. Suppresses frequencies above 1000 MHz.
68 Material: The Material is non-standard and only in stock on a few sizes. High Q up to 100 MHz.
75 Material: The material attenuates extremely well between 0.5 MHz and 20 MHz.
77 Material: The material is used in the form of ferrite toroidal coils for transformers, inductors and RF interference suppression.
F Material: The material has a high saturation flux density at high temperatures. Application of power conversion transformer. Good noise suppression between 0.5 and 20mhz.
H Material: Production of the material has been discontinued and limited quantities are available.
J Material: The material has low volume resistivity and low core loss in the range of 1 KHz to 1 MHz. For pulse transformers and low level broadband transformers. Excellent frequency attenuation, from 0.5 MHz to 20 MHz.
K Material: The material is mainly used for transmission line transformers from 1 MHz to 50 MHz.
W Material: The material is a high permeability material used for frequency attenuation from 100 KHz to 1MHz in EMI/RFI filters.
