Wurth Electronics introduces the SMD WE-KI, WE-RFI, and WE-RFH series


Wurth's RF InductorsWurth Electronics is a specialist in magnetics and has extended their existing range of RF inductors with the introduction of the SMD WE-KI, WE-RFI, and WE-RFH series. The ceramic- or ferrite-core inductors based on the wire-wound technology distinguish an excellent Q factor and a high-current carrying capacity. Additional benefits are ultra-low DC resistance for the best possible efficiency and stability across a high temperature range.

WE-KI SMD Wire-Wound Ceramic Inductors
WE-KI series (ceramic core) are especially developed for high-frequency applications. They offer an excellent Q factor and highest possible self-resonant frequencies up to 12.5 GHz. The WE-KIs have very-high thermal stability with industrial operating temperature of -40°C to 125°C. This series offers inductance tolerances of 5% (2% on request) and sizes ranging from 0402 up to 1008. The recommended soldering is reflow.

WE-RFI SMD Wire-Wound Ferrite Inductors
WE-RFI series (ferrite core) inductors are especially developed for RF applications such as RFID or low-frequency radio applications. Due to the ferrite core of the WE-RFI, it is an ideal choice for higher inductance values up to 47 uH. Furthermore, this wire-wound inductor is stable across high temperature ranges. Package sizes include 0805 and 1008.

WE-RFH SMD Wire-Wound Ferrite Inductors
The WE-RFH series (ferrite core) inductors are especially developed for RF applications such as telecommunication. With comparison to the WE-RFI, the WE-RFH has high inductances, but with even higher current-handling capability up to 760 mA. Additionally, this RF inductor boasts ultra-low DC resistance along with high thermal stability. Reflow is the recommended soldering profile.
