The 026011F from Coilcraft are Miniature RF Chokes available in inductance values up to 560 nH. They have a ferrite construction which ensures high current handling and a low DCR. These RF chokes are available in surface-mount packages that measure 0.70 x 0.30 x 0.55 mm and feature high impedance for RF isolation in cellular applications. They provide high inductance values for the 0201 sizes.
