744871330 Description

Short technical summary and product information.

The Würth Elektronik 744871330 is a WE-DD series shielded coupled inductor designed for surface-mount applications. It features two inductors with 33 µH each (20% tolerance), a 1:1 turns ratio, and a rated current of 1.2 A per coil at 40 K temperature rise. The saturation current is typically 2.8 A per coil, ensuring robust performance in power conversion circuits. Its DC resistance is 0.125 Ω typical (0.17 Ω maximum) per coil, minimizing power losses.

 

This inductor is shielded to reduce electromagnetic interference and is suitable for a wide operating temperature range of -40°C to +125°C. The self-resonant frequency is 6 MHz, and the maximum operating voltage is 80 V DC. The package measures 12.5 mm x 12.5 mm x 6.5 mm, making it suitable for compact designs.

 

Typical applications include DC-DC converters, SEPIC converters, and multi-phase buck converters where coupled inductors provide improved ripple cancellation and transient response. The component is compliant with RoHS, REACH, and Halogen-Free standards, with MSL level 1 for unlimited storage.

 

The 744871330 is supplied in tape and reel packaging. It is a reliable choice for automotive and industrial electronics requiring high efficiency and thermal stability.
