Multilayer Chip Beads with High Rated Currents

Share:

TDK Corporation (TSE:6762) has developed the new MPZ0603-H series of
multilayer chip beads for power lines in an IEC 0603 package (EIA 0201)
that feature twice the rated current and about half the DC resistance of
the existing MPZ0603-C series. Thanks to a newly developed technology
for the internal electrodes, TDK was able to reduce the DC resistance to
as low as 36 mΩ, thus increasing the rated current to as high as 1900
mA. The MPZ0603-H series offers high impedance values ranging from 22 Ω
to 120 Ω at 100 MHz. The new chip beads measure in with a miniature
footprint of 0.6 mm x 0.3 mm and a low insertion height of just 0.3 mm.
With their compact dimensions and excellent electrical specifications
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.

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. Thanks to
their 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.

Main applications

  • Noise suppression in the IC power supply lines in smartphones, audio
    players, PCs, and other devices

Main features and benefits

  • DC resistance as low as 36 mΩ approximately half that of existing
    products
  • Rated current as high as 1900 mA approximately twice that of existing
    products
