Ceramic SMT Inductors Portfolio with Compact High Q Types

Würth Elektronik extends its product family of WE-KI ceramic high-quality factor, high rated current SMT inductors.

Würth Elektronik has expanded its WE-KI product family with further ceramic inductor variants in 0603 and 0805 packages. Now the portfolio includes over 300 models in four sizes from 0402 to 1008, optionally with ±2 and ±5 per cent tolerance. With the new range of models, the available inductance values cover 1 to 1800 nH.

The SMT-mountable ceramic inductors are aimed specifically at high-frequency applications. A WE-KI variant is often used in telecommunications and antenna matching, for just one example. The Antenna Matching Service is additional design assistance from Würth Elektronik offering developers a means of reliably optimizing efficiency and range.

Compared to other technologies like multilayer ceramic inductors or thin-film inductors, WE-KI offers a high Q factor and very high rated currents. WE-KI is characterized by high thermal stability and is specified for the operating temperature range from -40 to +125ºC. The highest possible specified self-resonant frequency extends to 12.5 GHz. In order to facilitate the selection in designs, Würth Elektronik provides Spice models (LT Spice and PSpice) for simulation of all variants.

Design Kits are offered for WE-KI, i.e., sample collections with which developers always have different value inductors available. These “sorting boxes” are refilled by Würth Elektronik free of charge. Individual samples too are provided at any time. All products from the inductor series are available from stock without a minimum order quantity.
