TDK has launched the MPZ1608-PH series of multilayer chip beads for automotive and commercial power supply lines, with dimensions of 1.6 x 0.8 x 0.6 mm (L x W x H). Mass production began in May 2025.
The 1608-size chip beads achieve a rated current of 8 A, the highest in the industry, according to TDK as of May 2025. These components serve as noise suppression in power and signal circuits. Typically, circuits with currents of 8 A or more require multiple chip beads in parallel, leading to uneven current distribution. The MPZ1608-PH series reduces the need for multiple components, simplifying circuit design and enhancing power circuit quality.
Compared to circuits using two conventional 1608-sized chip beads, the MPZ1608-PH series halves the component footprint. The components are designed for reliability in high-temperature environments, with an operating temperature of up to +125 °C, suitable for automotive and industrial applications.
The chip beads are intended for power circuits in various equipment, including in-vehicle ECUs, power trains, vehicle body control, automotive multimedia (telematics), base stations, PCs, servers, set-top boxes, smart grids, robots, smartphones, and tablet devices. TDK plans to expand its lineup of high-rated-current products for automotive, industrial, and consumer equipment applications using proprietary materials and structural designs.
