The MLC1255-421MLC is a shielded power inductor for use in high-current DC-DC converters and VRD/VRM applications. It has a 10.5 mm × 11.4 mm body size and a maximum height of 5.6 mm. Its inductance is 0.42 µH with a ±20% tolerance, a typical DC resistance of 0.93 mΩ, and a saturation current of 21.1 A at a 10% inductance drop. The RMS current rating is 16.8 A for a 20°C temperature rise and 24.1 A for a 40°C rise. The part operates with an ambient temperature range of -40°C to +85°C and withstands a maximum part temperature of 125°C. It complies with AEC-Q200 Grade 3 and is rated for moisture sensitivity level 1. Terminations are RoHS-compliant tin-silver over copper. The component withstands three reflows at 260°C for 40 seconds each.
Coilcraft MLC12xx Series power inductors are mechanically rugged and magnetically shielded for use in high-density circuits. Their flat-wire construction provides excellent current handling and exceptionally low DCR, and soft saturation makes them perfect for VRM/VRD applications.
