Component

SMD transformer6-pin1:1.3 turns ratio5.0 kVAC isolationRoHS

LT51-113 is a compact 6-pin SMD isolation transformer specified for a 1:1.3 turns ratio and 5.0 kVAC isolation test.

Best for

  • Compact isolated converter and coupling circuits requiring a 1:1.3 transformer ratio
  • Designs requiring a 5.0 kVAC isolation test rating

Avoid if

  • A verified lifecycle status or formal qualification is required but not separately sourced
  • The required turns ratio, pinout, or leakage-inductance limit differs from the datasheet

Check before use

  • Confirm pin polarity from the winding connection diagram
  • Use the recommended PCB pad layout
  • Validate transformer performance at the actual switching waveform and operating temperature
