New electrodes double the current in multilayer chip beads

August 07, 2018 // By Nick Flaherty
TDK has launched a series of multilayer chip beads for power lines in an IEC 0603 package (EIA 0201) with twice the rated current and half the DC resistance of current devices.

The MPZ0603-H series uses a newly developed technology for the internal electrodes that reduces the DC resistance to as low as 36 mΩ, increasing the rated current to as high as 1900 mA.

The series also offers high impedance values ranging from 22 Ω to 120 Ω at 100 MHz in a footprint of 0.6 mm x 0.3 mm and a low insertion height of just 0.3 mm.

As the multifunctionality of portable devices such as smartphones continues to grow, high current ratings are becoming an increasingly important factor for components in the IC power supply lines. With the low DC resistance the MPZ0603-H chip beads not only offer a high rated current, but they also help lower the power consumption of devices.

The compact dimensions and specifications mean the ferrite beads are very well suited for a wide spectrum of noise suppression measures in the IC power supply lines of smartphones, audio players, PCs, and other devices. Mass production of the new series began in August 2018.
