Sumida Corporation (Tokyo, Japan) has announced their new magnetically shielded CDRH3D23 Series of power inductors for high-density power circuitry. With ferrite drum construction and a unique geometry, these devices yield high inductance values while measuring just 3.92 x 3.92 x 2.5 mm.

Applications include driver circuitry, DC-DC converters, switching power supplies and regulators, boost converters, buck-boost regulators, and more. These circuits may power wireless communications products and MM2M power circuitry. Standard packaging is carrier tape and reel packaging, 7.0”diameter reel, 500 pcs per reel.

Specifications include:

  • Inductance values from 0.47 – 47 μH.
  • DCR as low as 18.8 m (typ. @ 20° C).
  • RoHS compliant and halogen-free.  
  • Full-rated temperature range of -40° to +105° C.
  • Solder reflow temperature to 260° C peak.
  • Compliance with IPC/JEDEC Moisture Sensitivity Level 1.
  • Unlimited floor life at ≤ 30° C / 85% RH.
