Wurth Elektronik Wirewound Shielded Surface Mount Inductor 39μH ±20% 4.1A Idc 1210 WE-PD 7447709390

Wurth Elektronik 7447709390 WE-PD series wirewound shielded surface mount inductor provides 39 μH inductance with a ±20% tolerance, designed primarily for power electronic applications requiring compact size and high current handling. This component is built to withstand a wide operating temperature range from -40°C to +125°C and complies with the automotive-grade AEC-Q200 standard.

The 1210 case size with 12 mm length and depth combined with a 10 mm height offers a low-profile but robust footprint for surface mounting on printed circuit boards. The magnetic shielding construction minimizes leakage fields, facilitating high efficiency and low noise operation in power supply circuits and switching regulators. Its maximum DC current rating of 4.1 A and low DC resistance of 56 mΩ reduce power losses and heat generation.

The inductor is optimized for applications such as switching regulators with low operating voltages, integrated DC/DC converters, and graphics card power supplies that demand high efficiency exceeding 86%. The recommended solder profile is reflow, making it compatible with standard SMT manufacturing processes.

Packaging by tape and reel supports high-volume automated PCB assembly workflows. The WE-PD series inductors comply with RoHS environmental standards, ensuring they meet strict hazardous material restrictions.

The 6 MHz maximum self-resonant frequency allows for stable operation at higher switching frequencies common in modern power electronics. This combination of features makes the Wurth Elektronik 7447709390 an excellent choice for industrial, automotive, and commercial electronic systems requiring reliable inductive components with strong current capacity and shielding.

This high-current shielded wirewound inductor is suitable for demanding power electronics applications. The component offers robust operating temperature performance from -40°C to +125°C. Complies with automotive AEC-Q200 standards ensuring reliability in harsh environments.

Packaging in tape and reel supports effective automated placement on PCBs. Low DC resistance and high saturation current reduce losses and improve efficiency. Magnetic shielding reduces interference, suitable for high-efficiency switching power supplies.

Compact 1210 surface mount footprint optimizes board space on industrial and automotive PCBs. RoHS compliance guarantees adherence to environmental regulations.
