Product Description
Wurth Elektronik 744912147 WE-CAIR series shielded surface mount air coil inductor provides a precise inductance of 47 nH with ±5% tolerance, designed for high-performance and reliability in demanding applications. Featuring a ferrite core, this inductor supports a maximum DC current of 3 A and offers a maximum operating temperature of 125°C.
The 4248 package size and tape & reel packaging format make this component fully compatible with automated surface mount technology (SMT) assembly processes, increasing production efficiency and yield. The inductor is shielded to minimize electromagnetic interference, thereby improving overall circuit performance in sensitive RF and broadband filter applications.
WE-CAIR inductors exhibit a minimum quality factor (Q) of 100, ensuring low losses at high frequencies up to the maximum self-resonant frequency of 2.1 GHz. This makes them ideal for broadband filtering, RF decoupling, and other high-frequency electronic circuits in automotive and industrial environments compliant with AEC-Q200 standards.
The temperature range of -40°C to 125°C allows reliable operation in harsh environmental conditions. The simple 2-pin solder termination style supports conventional soldering methods. Dimensions of 4.83 mm height and 4.2 mm depth allow for compact PCB layouts in space-constrained designs.
Ferrite core with shielded construction minimizes EMI. Suitable for high current RF applications with up to 3A DC current. Automotive grade compliant with AEC-Q200 quality standards. Compact 4248 SMD package compatible with pick and place automated assembly.
Wide temperature range supports industrial environments. Explore more components from Wurth Elektronik and our extensive Surface Mount Inductors category to find the perfect solutions for your electronic design and manufacturing needs.
