Technical Features

The MagWave T1V-140/050 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 36 mm, inner diameter 23 mm, height 12.7 mm
AL (nH): approx. 885 ±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
