CR43NP-3R3MC Description

Short technical summary and product information.

The Sumida CR43NP-3R3MC is a fixed inductor from the CR43 series of unshielded wirewound power inductors. It features a ferrite drum core and is designed for surface-mount assembly. Key electrical specifications include a nominal inductance of 3.3 µH with ±20% tolerance, a rated current of 1.44 A (defined as the DC current at which inductance decreases to 90% of initial value or a temperature rise of 40°C, whichever is lower at 20°C ambient), a maximum DC resistance of 86.2 mΩ at 20°C, and a typical self-resonant frequency of 60 MHz. The inductance is tested at 7.96 MHz.

 

This inductor operates over a temperature range of -40°C to +100°C (including coil self-heating) and can be stored in the same range. It is RoHS compliant and halogen free. The compact package measures 4.80 mm (length) by 4.30 mm (width) with a maximum height of 3.50 mm.

 

Typical applications include DC-DC converter circuits in A/V equipment, LCD TVs, digital still cameras, game machines, HDDs, and notebook PCs. The unshielded construction and wirewound design make it suitable for a variety of general-purpose power conversion and signal filtering tasks.
