Highest current 1608 chip bead handles up to 8A

TDK has recently expanded its multilayer chip bead range specifically designed for automotive power supply lines by introducing the MPZ1608-PH chip bead. This new addition to the lineup is capable of handling currents of up to 8A, making it a valuable component for high-power applications within the automotive industry.

The MPZ1608-PH chip bead boasts compact dimensions of 1.6 x 0.8 x 0.6 mm while achieving a rated current of 8A, which TDK claims to be the highest in the industry. Chip beads play a crucial role as noise suppression components in power and signal circuits, ensuring optimal performance and reliability in electronic systems.

Traditionally, circuits with currents exceeding 8A required the parallel use of multiple chip beads to manage noise levels effectively. However, this approach often led to uneven distribution of current among the ferrite beads, impacting overall circuit efficiency.

• For automotive applications demanding even higher current handling capabilities, TDK also offers the 12A 2520 chip bead, catering to the evolving needs of automotive designs.

By offering a chip bead with an 8A current rating, TDK aims to simplify circuit design and reduce the number of components required compared to conventional methods. This advancement not only streamlines the circuit structure but also enhances the quality of power circuits in various automotive applications, including in-vehicle ECUs, powertrain systems, vehicle body control units, automotive multimedia systems, base stations, PCs, servers, set-top boxes, smart grids, and robotics.

The MPZ1608-PH series stands out for its ability to halve the component footprint when compared to circuits utilizing two conventional 1608-sized chip beads. Additionally, these chip beads are designed to operate reliably at temperatures up to +125°C, making them suitable for use in demanding high-temperature environments commonly found in automotive and industrial settings.

With mass production of the MPZ1608-PH chip bead series commencing this month, TDK is poised to meet the growing demand for high-performance components that cater to the evolving requirements of automotive electronics and industrial applications.
