The Sumida CDMT40D20 Series Power Inductors are the first of a new family of components, designed to meet the demanding requirements of today’s portable devices and communications hubs. Exclusive metal-hybrid construction provides effective magnetic shielding with DC resistance lower than conventional SMD inductors. This can improve circuit battery life to a level comparable to larger inductors. Saturation current for the 0.24µH value is nearly 19 amps. Maximum size for all values is just 4.3 x 4.3 x 3.1 mm.
The CDMT40D20 has the lowest loss performance in the industry for inductors in its size class. Two kinds of metal materials are used in the over-mold process in order to achieve high-current performance and high-magnetic shielding. Wire gauge varies with device inductance.
Inductance values range from 0.22 μH – 4.7 μH. DCR is as low as 5.5mW (typ.@ 20°C). The device is RoHS compliant and halogen-free. The CDMT40D20 Series offers a full-rated temperature range of -40° to +125°C, and solder reflow temperature to 260°C peak. Complies with IPC/JEDEC Moisture Sensitivity Level 1, for unlimited floor life at ≤30 °C/85% RH.
Applications include portable smart devices, telecommunications base stations, servers, SSD, DC-DC converters, and other designs requiring the combination of shielding, high current and very low profile. Standard packaging is carrier tape on 7.0”diameter reels; 500pcs per reel.
Like other Sumida products, CDMT40D20 Series power inductors meet or exceed the highest industry standards for quality and repeatability. Full application engineering support is available.
