A single component replaces 4 individual ferrite beads, reducing PCB area and pick-and-place cycles. Low 0.1 ohm DCR preserves signal integrity. For data bus and multi-line EMI suppression.","working_principle":"Four sintered ferrite material elements on a single ceramic substrate. Each element acts as an independent high-frequency resistor (impedance rises with frequency due to ferrite magnetic loss). At DC and low frequency, the impedance is just the copper DCR. At high frequency, the ferrite impedance absorbs EMI energy as heat.","pin_description":"
