4CX300Y

cpi | 4 cx300y/ 8561 cpi | 4cW50,000J 4cx300y/8561 The 4CX300Y/8561 is a compact power tetrode having a maximum plate dissipation rating of 400 watts. It may be operated at maximum ratings to 110 MHz. The ceramic/metal construction and the internally utilized electrode structure combine to make the 4CX300Y/8561 especially durable and free from mechanically induced noise under conditions of severe acceleration caused by shock or vibration. chaRacteRistics Plate Dissipation (Max.)
