Note:

  1. Saturation magnetic induction of 1J34, 1J40, 1J51 and 1J52 is measured at a magnetic field intensity between 200A/m and 2400A/m. Saturation magnetic induction of 1J65, 1J67 and 1J83 is measured at a magnetic field intensity of 800A/m.
  2. The core loss of 1J40(Ⅰ) should be measured at the temperature -40℃, +20℃ and +100℃.
  3. P1/400 and P1/4000 mean the core losses at 400Hz and 3000Hz respectively and they should be tested at the peak value of magnetic induction of 1T.
  4. Brs referring to the squareness ratio(Br/Bm) means the magnetic induction at a magnetic field intensity of 80A/m.

Feature

With crystallization/magnetic texture and rectangular hysteresis loop, fairly high maximum permeability and saturation magnetic induction.

Application

Components of medium/small power magnetic amplifier, double polarity pulse transformer, saturation inductor, magnetic regulator, contactless relay, contact rectifiers reactor, amplitude modulator, pinnacle suppresser, calculation equipment and apparatus etcs.
