About this product
SMD 0805 magnetic bead (ferrite bead inductor) with an impedance of 150 Ω at 100 MHz, used to suppress high-frequency noise and EMI/RFI on power and signal lines. It has a DC resistance of 80 mΩ, a rated current of 400 mA and a package size of 2.0 × 1.2 × 0.9 mm. It is commonly used to filter supply rails in digital and RF circuits.

Frequently asked questions
What is this component used for?
It filters high-frequency noise on power rails and signal lines, for example between a regulator and the supply pin of a sensitive IC.
How much voltage drop does it add at rated current?
With 80 mΩ DC resistance at the rated 400 mA, the drop is about 32 mV (V = I × R). Keep the circuit current below the rated value, and choose between the 100 Ω and 150 Ω versions based on the noise frequency and the impedance curve in the datasheet.
