Efficient Noise Suppression – VITROPERM 550 HF

Nanocrystalline cores offer volume, weight and cost optimized HF-designs

VITROPERM® 550 HF is the latest addition to the family of nanocrystalline alloys that are characterized by outstanding properties. The newly developed alloy enables next-generation components with optimized size and weight, especially for HF-noise reduction. Cores made from this alloy enable high RFI-noise suppression, particularly,  in the HF-range in innovative filter designs with higher performance for future applications. 

Benefits:

  • Significantly reduced volume/weight due to improved HF-properties
  • Superior HF-attenuation compared to standard VP 500 F
  • Low core losses due to lower eddy currents
  • Excellent thermal stability over a wide temperature range 

Benefits of using VP 550 HF in your application

Comparison of the impedance IZI (f) of VITROPERM 550 HF vs. VITROPERM 500 F and typical ferrites.  In each case, the core size is 25 x 20 x 10 mm, wound with 14 turns, 1.4 mm.

VITROPERM 550 HF provides a significantly improved performance with an identical core size. Alternatively, an identic performance can be achieved with much smaller cores, resulting in a remarkable cost reduction.
