Würth Elektronik has extended its series of WE-RFI inductors that are offered in sizes 0402 and 0603, which can be used as inductors for HF applications or as ferrites for interference suppression. These new inductors are smaller and complement the existing sizes of 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 behavior. They offer high inductance values from 20 nH up to 47 µH. These HF inductors are characterized by low DC resistance and consequently a high rated current of up to 1.91 A at ΔT = 40 K. A design kit is also available for this component group, which Würth Elektronik will always replenish free of charge, so developers always have inductances of different values to hand.
The WE-RFI inductor series is AEC-Q200 Grade 3-compliant and operates over a temperature range from -40°C to +85°C. They are available in surface-mount packages and require reflow-based soldering for attachment.
