Multilayer chip beads deliver the highest rated current of 8A for power supply lines

TDK Corporation has extended its MPZ1608-PH series of large-current multilayer chip beads for automotive and commercial power supply lines (1.6mm x 0.8mm x 0.6mm – L x W x H). Mass production of the product series began in May 2025.

These 1608-size chip beads for power supply lines attain a rated current of 8A, the industry's highest value. Chip beads are employed as noise suppression components in power and signal circuits. In a circuit with a current of 8A or more, usually two or more chip beads must be employed in parallel. This has the disadvantage that the current is not evenly distributed between the ferrite beads. The company's new product simplifies the circuit structure because fewer components are needed than conventional methods, improving the quality of power circuits.

The MPZ1608-PH series of products halves the component footprint compared to circuits employing two conventional 1608-sized chip beads. Moreover, the highly reliable components with a specified operating temperature of up to +125C are designed for high-temperature environments like automotive and industrial equipment applications.

With the company's proprietary materials and structural designs adapted to market needs, the company is committed to extending its lineup of high-rated current products in the automotive, industrial equipment, and consumer equipment areas. These chip beads will serve as EMC components that contribute to improving the quality of power circuits.
