74451133 Description

Short technical summary and product information.

The Würth Elektronik 74451133 is a surface-mount shielded power inductor from the WE-PD3 series. It features a drum core, wirewound construction with a ferrite core, providing an inductance of 33 µH with ±20% tolerance. The inductor is rated for a maximum current of 0.6 A (ΔT=40 K) and has a typical saturation current of 0.15 A. The DC resistance is 0.114 Ω typical and 0.19 Ω maximum. The self-resonant frequency is typically 14.5 MHz. The component is shielded to minimize electromagnetic interference. It is packaged in a nonstandard case measuring 12.70 mm x 10.30 mm x 3.00 mm, suitable for surface mount assembly. The operating temperature range is -40°C to +125°C. The inductor is RoHS and REACH compliant, halogen-free, and has MSL Level 1. Typical applications include power supplies, DC-DC converters, and EMI filtering circuits where high inductance and current capability are required in a compact SMD package.
