These are ideal to construct Baluns for 3 to 50MHz or EMI noise suppression above 200MHz.<br \/>\nFerrite toroid&#8217;s can be used as common mode choke, impedance transformer or balun.<br \/>\nCommon mode choke. 61-Material is a good wide band common mode suppression solution in the high frequency range from 25 up to 2000 MHz. If you use multiple cable turns around the ring core, the suppression will increase while the frequency will decrease. Single turn frequency range 200 \u2013 2000 MHz. Multiple turns 25 \u2013 300 MHz. Wide band transformer. You can make excellent impedance transformers in the frequency range from 15 up to 200 MHz as well.<br \/>\nTypical applications are end fed antenna impedance transformers, off center fed antenna impedance transformers or 1:1 Balun\u2019s.<\/p>\n<p>Specifications:<br \/>\nFair-Rite 5961003801: MnZn Ferrite Toroid, 61 material, wide band transformers up to 200 MHz, permeability ui=125<br \/>\nFair-Rite 5961003801 Size: Diameter 61mm, Height 12.55mm Hole Size 36mm, color Grey<br \/>\nFerroxcube 4C65 Equivalent<br \/>\nAL (nH): 170<br \/>\nSuitable for: Broadband and EMI filters<br \/>\nSuitable for: HF high power balun up to 1 kW.<br \/>\nOuter diameter (metric): 61 mm<br \/>\nInner diameter (metric): 35.55 mm<br \/>\nHeight (metric): 12.7 mm<\/p>\n","protected":false},"excerpt":{"rendered":"<p>FT240-61: Original Fair-Rite high quality toroid.
