Inductors with high quality factors and low frequency range

Stocked by Digi-Key, Wurth Electronics' air coil inductors, WE-CAIR, are characterised by high quality factors and are also in the low-frequency range (Q greater than 100). The resonance frequency is very high. The air coil inductors also guarantee a greater rated current compared to other RF inductors. In addition, the inductors have a high-temperature stability. They are available in the following sizes: 1322, 3136, 1340, 4248, and 3168. The design sizes 1322 and 1340 are one-third flatter than the other size of products. The 1322 type, in the series, has a 20% higher rated current with the conventional ceramic coils in the 0805 chip format. Its high Q-factor remains stable even in the high MHz range thus enabling these extremely flat air coils to be used over a broad spectrum of frequencies. Thanks to the air coil, the inductance can be kept constant all the way into the GHz range, meaning that these air coils are predestined for use in radio-engineering applications. A compact design combined with a high Q-factor and a high-rated current enables use in HF front-ends of all kinds and for the adjustments of the impedance of antennas for diverse frequency bands.
