The 0201AF Series from Coilcraft are Wire-Wound Ferrite Core Chip Inductors with inductance values of up to 200 nH. They are optimized for RF isolation in applications ranging from 900 MHz to 9 GHz. The inductors have a low-loss ferrite construction that ensures high impedance, high current handling capability, and low dynamic contact resistance (DCR) in a single package. These RF inductors have a DCR of less than 0.15 Ohms and a self-resonant frequency of 3400 MHz. They are available in surface-mount packages that measure 0.36 x 0.58 x 0.18 mm with tape and reel and are ideal for low-frequency filter applications.
