FT-37-43 / 5943000201 Nucleo toroidale in ferrite, µi=800, per filtri EMI e balun RF

Technical Features

The MagWave T1V-037/013 toroid is a ferrite component from the T1V series, designed for RF and HF applications. Thanks to the 1V (43) ferrite mix and its compact size, it is ideal for building RF chokes, baluns, and impedance transformers for both amateur and professional use.

• Applications:
  
  • EMI/RFI Suppression (20 MHz – 250 MHz)
  • Balun / RF Transformers (1 MHz – 25 MHz)
• Initial permeability: 800 µi
• Dimensions: outer diameter 9.5 mm, inner diameter 4.8 mm, height 3.18 mm
• AL (nH): approx. 350 ±20%
• Curie temperature: above 130 °C

Benefits

• Compact and efficient: perfect for space-constrained projects
• Noise suppression: excellent for reducing common-mode currents and improving signal quality
• Versatility: compatible with End Fed, OCF antennas and 1:1, 4:1, 9:1 transformers
• Thermal stability: maintains performance even under critical operating conditions
