CDRH4D28NP-3R3NC Description

Short technical summary and product information.

The Sumida CDRH4D28NP-3R3NC is a shielded SMD power inductor with a ferrite drum core construction. It offers an inductance of 3.3 µH (measured at 100 kHz) with a tolerance of ±30%. The component is rated for a DC current of 1.57 A, defined as the current at which inductance drops to 65% of nominal or temperature rise reaches 40°C, whichever is lower. Maximum DC resistance is 49.2 mOhm.

 

Designed for surface mount assembly, the inductor measures 4.70 mm x 4.70 mm with a maximum height of 3.00 mm. It is packaged in tape and reel with 2000 pieces per reel. The operating temperature range is -40°C to +100°C, and it can withstand a peak solder reflow temperature of 260°C. Moisture sensitivity level is 1 (unlimited floor life).

 

Typical applications include DC-DC converter circuits in mobile phones, PDAs, MP3 players, HDDs, DSC/DVC, and notebook PCs. The shielded construction minimizes electromagnetic interference, making it suitable for space-constrained designs.
