A ferrite bead can be modeled as a simplified circuit consisting of resistors, an inductor, and a capacitor, as shown in Figure 1a. RDC corresponds to the dc resistance of the bead. CPAR, LBEAD, and RACare (respectively) the parasitic capacitance, the bead inductance, and the ac resistance (ac … Meer weergeven An effective method for filtering high frequency power supply noise and cleanly sharing similar voltage supply rails (that is, analog and digital rails for mixed-signal ICs) while preserving high frequency isolation … Meer weergeven Selecting the right ferrite bead for power applications requires careful consideration not only of the filter bandwidth, but also of the … Meer weergeven This section describes three damping methods that a system engineer can use to reduce the level of resonant peaking significantly (see Figure 7). Method A consists of adding a series resistor to the decoupling … Meer weergeven Resonance peaking is possible when implementing a ferrite bead together with a decoupling capacitor. This commonly overlooked effect can be detrimental because it may amplify ripple and noise in a given … Meer weergeven WebFerrite Beads & Ferrite Chips are in stock and ship same-day at Mouser Electronics from industry leading manufacturers.
