Coilcraft wirewound ferrite beads provide superior broadband performance compared to both low- and high-DCR chip ferrite beads. Wirewound ferrite beads provide a high magnitude of attenuation over a wide frequency range, whereas traditional thick-film chip ferrite beads have limited options for both attenuation and frequency range. In addition to offering better attenuation and frequency performance than their chip counterparts, wirewound ferrite beads provide lower DC resistance (DCR) and higher current ratings without core saturation, resulting in the highest possible performance in the smallest size.
1812CANbus common mode chokes from Coilcraft are designed for noise suppression on CAN and CAN FD. As well they can be used in FlexRay automotive bus systems. With 50% lower DCR and higher current handling than other CANbus chokes in the market.
Current sense transformers from Coilcraft offer sense currents to 40 Amps! With a wide selection of sizes and turns ratios with footprints as small as 4.4 X 4.5 mm they are ideal for switching power supplies.
