The Sumida CDPH4D19FNP-3R3MC is a shielded SMD power inductor designed for DC-DC converter applications. It features a ferrite drum core construction that provides high inductance stability and low core losses. The inductor is magnetically shielded to minimize electromagnetic interference.
Key electrical specifications include a nominal inductance of 3.3 µH measured at 100 kHz, with a tolerance of ±20%. The maximum DC resistance is 33 mOhm (typical 26 mOhm) at 20°C. The saturation current is 1.5 A (when inductance drops to 65% of nominal), and the temperature rise current is 3.8 A for a 40°C rise. Operating temperature range is -40°C to +105°C including self-heating.
The inductor is housed in a nonstandard surface mount package with dimensions 4.9 mm x 4.9 mm x 2.0 mm maximum. It is supplied in tape and reel packaging with 1000 pieces per 7-inch reel. The component is RoHS compliant and has a moisture sensitivity level of 1.
Typical applications include notebook PCs, MP3 players, mobile phones, digital cameras, and other portable electronics where efficient DC-DC conversion is required. The shielded design makes it suitable for noise-sensitive circuits.
