Product Description
Wurth Elektronik model 7447732115 is a 15μH ±20% unshielded surface mount inductor from the WE-PD2 series. Its ferrite core construction ensures magnetic stability and high performance in compact surface mount circuits. The 3521 package size (3.5mm length, 2.1mm height, and 3mm depth) allows integration into dense PCB layouts, supporting automated soldering via tape & reel packaging using reflow soldering profiles.
This component supports a maximum DC current of 640mA and has a low DC resistance of 430mΩ, facilitating efficient current flow with minimal energy loss. Rated for operation in a broad temperature range from -40°C to 125°C, it is ideal for industrial and commercial electronics applications that demand thermal and electrical reliability.
The inductor is unshielded, permitting optimal attenuation in MHz frequency ranges and is standardized to JEDEC JS709B, while meeting RoHS and REACH environmental compliance standards. Its core material is ferrite, which contributes to effective magnetic performance and durability.
Applications include switching regulators, embedded PC-Cards, graphic card power supplies, mainboards, and integrated DC/DC converters where reliable inductance and current capacity are critical to circuit functionality.
Compact 3521 surface mount package for space-efficient designs. Ferrite core provides magnetic stability and low core losses. Operational temperature from -40°C to +125°C enabling use in harsh environments. Maximum DC current rating of 640mA to handle moderate power loads.
Low resistance of 430mΩ reduces heat buildup during operation. Compliance with JEDEC JS709B, RoHS, and REACH ensures regulatory conformity. Packaging in tape & reel for streamlined automated assembly processes.
This Wurth Elektronik WE-PD2 7447732115 Surface Mount Inductor aids designers in achieving compact, efficient, and reliable power management circuits.
