WE-CAIR SMD Air Coil Inductors

Würth Elektronik WE-CAIR SMD Air Coil Inductors are especially suitable for high-frequency applications by offering high self-resonant frequency and >100 Q factor. These characteristics allow a 50% wider frequency range than previous RF coils. In addition, these air coils have a low-temperature dependence, resulting in inductance stability across the entire operating range. Other features include inductance up to 538nH, up to 4A current, operating temperature range up to 125°C, and good solderability (tinned connector pins).
