0.47 µHmolded power inductorshielded2.2 mΩ max DCR40 A typical IsatSMD

ZEMS1040-R47M is a 0.47 µH shielded molded power inductor for high-current DC/DC and point-of-load designs. It is specified with 2.20 mΩ maximum DCR, 40 A typical Isat, and 30 A typical temperature-rise current.

Best for

  • High-current buck converters
  • Point-of-load power stages
  • Distributed DC/DC power systems

Avoid if

  • A guaranteed saturation-current limit is required
  • The application cannot accommodate an approximately 11.5 mm × 10.0 mm footprint

Check before use

  • Validate current derating over the full -55°C to +125°C operating range
  • Confirm temperature rise at actual copper area and airflow
  • Verify reflow process compatibility and PCB land pattern
