Wurth Elektronik WE-MK Unshielded Multilayer Surface Mount Inductor with Ceramic Core 22 nH 5 % Tolerance 150 mA 7447820122

Wurth Elektronik 7447820122 is an unshielded multilayer surface mount inductor featuring a ceramic core and an inductance of 22 nH with a tolerance of 5 %. It supports a maximum DC current of 150 mA and includes multilayer construction that provides high stability and reliability over a wide operating temperature range of -55°C to 125°C. This inductor is designed for surface mount technology (SMT) with compact dimensions of 0.6 mm length, 0.3 mm height, and 0.3 mm depth, making it ideal for space-constrained high frequency electronic circuits.

The high self-resonant frequency of 1.8 GHz allows for excellent performance in applications such as Bluetooth, wireless LAN, and other RF circuits. It is certified to meet automotive standard AEC-Q200, ensuring suitability for automotive and other demanding industrial applications. The product complies with RoHS, REACH regulations, and IEC 61249-2-21 and JEDEC JS709B standards, emphasizing its environmental compliance and quality.

This inductor features low maximum DC resistance of 1000 mΩ and a minimum quality factor of 4, which contributes to improved electrical efficiency. The multilayer ceramic core construction integrates the coil within a robust ceramic substrate, which helps maintain inductance stability across temperatures and reduces electromagnetic interference due to the unshielded design.

The termination style is optimized for automated surface mounting, facilitating high throughput manufacturing on modern PCBs. Supplied on tape and reel packaging, it supports automated pick-and-place assembly systems for mass production.

Common industrial uses include electronics manufacturing for communication devices, networking equipment, automotive electronics, and other industrial-grade electronic assemblies requiring small, reliable RF inductors with tight tolerances and environmental compliance.
