Here the manufacturer responds to increasing 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, the WE-RFI inductors attain 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 offer high inductance values from 20 nH up to 47 µH. They are characterised by low RDC and consequently a high rated current of up to 1.91 A at ΔT = 40 K. A design kit is available for this component group, which Würth Elektronik will always replenish free of charge, so developers always have inductances of different values to hand.
