CDRH4D28NP-2R2NC Description

Short technical summary and product information.

The CDRH4D28NP-2R2NC is a shielded surface mount power inductor from Sumida Corporation's CDRH4D28 series. It features a ferrite drum core construction and is magnetically shielded, making it suitable for DC-DC converter applications in portable electronics. Key electrical specifications include an inductance of 2.2 µH (measured at 100 kHz) with ±30% tolerance, a maximum DC resistance of 31.3 mΩ (typical 23.2 mΩ at 20°C), and a rated current of 2.04 A (defined as the DC current at which inductance drops to 65% of nominal or temperature rise reaches 40°C, whichever is lower). The component operates over a temperature range of -40°C to +100°C including self-heating. It is packaged in a nonstandard surface mount case measuring 4.7 mm × 4.7 mm × 3.0 mm (with maximum overall dimensions including terminals of 5.0 mm × 5.0 mm × 3.0 mm). The inductor is supplied in tape and reel packaging with 2000 pieces per 12.9-inch reel, and is compatible with 260°C peak reflow soldering. It is RoHS compliant and has MSL 1 moisture sensitivity level.
