ZEMS1265-121M is a shielded 120 µH molded SMD power inductor intended for DC/DC and point-of-load converters. It is specified for 3.5 A typical saturation current, 2.2 A typical heating current, and 235 mΩ maximum DCR.

Best for

  • Moderate-current DC/DC converter output filtering
  • POL converter power stages
  • Distributed power systems
  • Battery-powered equipment

Avoid if

  • Applications requiring current above the specified thermal or saturation limits
  • Designs needing a lower DCR than 235 mΩ maximum
  • Applications requiring verified lifecycle or qualified automotive status

Check before use

  • Evaluate inductance under actual DC bias and switching ripple.
  • Confirm temperature rise at the installed PCB copper area and ambient temperature.
  • Use the recommended land pattern and reflow process.
