Wurth 0603 WE-MK Series Multilayer Ceramic Inductors Wurth WE-MK Series 0603 multilayer ceramic inductors are suitable for use in high frequency circuits such as tuners, transponders and HF amplifiers. Other applications include pagers, oscillators, laptops, PCMCIA-cards, Bluetooth, wireless LAN and filter circuits. These inductors offer stable inductance over temperature, inductive tolerances of 5%; ±0.3 nH and an high self-resonant frequency. The windings are printed on ceramic substrate and reflow or wave soldering is recommended for this series of multilayer inductors.
