SERIES LL-68500-TH

Thru-Hole Units

MIL-STD-1553 Transformers

 

These low profile data-bus transformers are designed with the lowest leakage inductance, to achieve the optimum pulse characteristics in high frequency applications for the commercial, military, and aerospace industries.

SPECIFICATIONS:

  • Performance to MIL-PRF-21038 requirements
  • IMPEDANCE: Minimum value shown in table.
    These values will be met from 75 KHz to 1 MHz over temperature of -55°C to +130°C
  • DROOP:  20% Max.
  • OVERSHOOT: 1V peak
  • COMMON MODE REJECTION (CMR):  45 dB min.
  • DIELECTRIC WITHSTANDING VOLTAGE:   100Vrms
  • INSULATION RESISTANCE:  10K MOhms@100 V DC
