Series of wire-wound ferrites extended

Würth Elektronik now provides its WE-RFI inductors in sizes 0402 and 0603, which can be used as inductors for HF applications or as ferrites for interference suppression. Here, the manufacturer responds to growing miniaturisation and complements the existing sizes 0805 and 1008. The components are suitable as low-pass filters (for filtering high-frequency noise), data line filters, supply voltage decoupling, low-frequency radio applications, and RFID.

As wire-wound ferrites, these inductors achieve higher impedances than normal ferrites, even at high frequencies and over a wider bandwidth. Unlike multilayer ferrites, they show no DC bias behaviour.

As HF inductors, they provide high inductance values from 20nH up to 47µH. Low RDC characterises them and, consequently, a high-rated current of up to 1.91A at ΔT = 40K. A design kit is obtainable for this component group, which the company will always replenish free of charge, so developers always have inductances of different values to hand.
