  • 500 Vrms, one minute isolation (hipot) between primary and secondary
  • Ideal for Flyback, SEPIC, Ćuk, Zeta and other applications
  • High efficiency and excellent current handling
  • Can also be used as two single inductors connected in series or parallel, as a common mode choke or as a 1 : 1 transformer.
  • AEC-Q200 Grade 1 (−40°C to +125°C)

メモ
  1. When ordering, please specify termination code: MSD1278H-105KED. 
  2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value.
  3. DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
  4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
  5. Leakage inductance is for L1 and is measured with L2 shorted
  6. Isat: DC current, at which the inductance drops the specified amount from its value without current. It is the sum of the current flowing in both windings.
  7. Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. Determine temperature rise.
  8. Irms, one winding: Maximum current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. Determine temperature rise.

終端処理:

  • E = RoHS compliant matte tin over nickel over phos bronze.
  • T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)
