The DLP11TB series of 0504 chip common mode choke coils, which are designed to reduce undesirable radiation noise in electronic equipment is now available from Murata. The high-precision film inductor forming technology was used to attain an improved cut-off frequency in the transmission characteristics. The cut-off frequency of choke coils has been boosted to 8GHz or more, enabling USB 3.0 SuperSpeed signals to be transmitted at an enhanced quality level. The formulation of the USB 3.0 standard under which the data transmission speed has increased from the 480Mbit/s. The USB 3.0 standard has added the SuperSpeed mode, enabling data to be transmitted at up to 5Gbits/s. With the increased data transmission speed, signal frequencies have become much high and this has made it difficult to deal with noise issues while maintaining an enhanced signal quality using a common mode choke coil. The devices' boosted cut off frequency has reduced the effects of noise on signals to the absolute minimum. Features include a common mode impedance of 80Ω at 100MHz, and the coils match the characteristic impedance of 90Ω from the USB 3.0 standard. Electronica: Hall B5: stand 107
