High-reliability chip beads for use in automotive
TDK Corporation has developed the MMZ1608-HE series of high-reliability chip beads for automotive use, compatible with high-durability solder in 150 degrees C environments.
This series offers high-reliability chip beads for applications associated with engine control modules, anti-lock brake systems, electric power steering, electric and hybrid electric vehicles, inverters and LED headlights.
In high-temperature automotive environments, such as engine compartments, high-durability solder is increasingly used to prevent solder cracks in the bonds between chip components and the mounting substrate. Since high-durability solders do not stretch easily and impart higher stress compared with conventional solders, they place a large load on chip components and do not meet the reliability requirements of existing chip beads.
With improvements to the terminal electrode material and plating process, the MMZ1608-HE series improves the bonding strength between the terminal electrode and plating, making it suitable for use with high-durability solder in 150 degrees C environments.
The four products in the series have a rated current max ranging from 200 to 300 at 150 degrees C, DC resistance max between 0.15 to 0.5, and impedance from 120-1000, respectively.
TDK’s portfolio features passive components such as ceramic, aluminum electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices.
The product range also includes sensors and sensor systems such as temperature and pressure, magnetic and MEMS sensors. In addition, TDK provides power supplies and energy devices and magnetic heads. These products are marketed under the product brands TDK, EPCOS, InvenSense, Micronas, Tronics and TDK-Lambda.
TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America. In fiscal 2021, TDK posted total sales of $13.3 billion and employed about 129,000 people worldwide.
