The product is a chip inductor in the EXCCL series. It has the characteristic of suppressing the noise of the power line and the high-speed signal line. The product has three sizes: 4.5x3.2x1.8, 3.2x2.5x1.6, and 3.2x1.6x1.6. The rated current is 3, 4, and 5 amps respectively.
The Panasonic chip bead core series (EXCCL, EXCML, EXC3B) provides effective noise suppression for power lines and high‑speed signal lines. The parts feature low DC resistance, low or high impedance options, and are suitable for digital equipment such as PCs, printers, audio/video devices, AC adapters and switching power supplies.
