0.22 µHMolded power inductorShieldedLow DCRSMDZEMS0420

ZEMS0420-R22M is a 0.22 µH molded and shielded SMD power inductor for compact high-current converter stages. It specifies 6.6 mΩ maximum DCR, 13 A typical saturation current, and 9.5 A typical temperature-rise current.

Best for

  • Compact high-current DC/DC converters
  • Point-of-load converters
  • Battery-powered power stages

Avoid if

  • Applications requiring guaranteed saturation current rather than a typical value
  • Designs exceeding the specified 30 VDC maximum voltage
  • Circuits without thermal validation at the intended ambient temperature

Check before use

  • Inductance drop under DC bias
  • DCR loss at operating current
  • 40°C temperature-rise margin
  • PCB land pattern and solder profile
