KYOCERA AVX Unveils Advanced Multilayer Varistors for Automotive Applications

KYOCERA AVX, a distinguished global manufacturer recognized for its innovative electronic components, has launched its latest high-temperature multilayer varistors (MLVs) tailored for 48V automotive power systems. This new offering enhances the company's renowned TransGuard® VT Series, setting a new standard in overvoltage protection and EMI/RFI attenuation for automotive applications.

Meeting the Structural Demands of Modern Vehicles

With the rise of electronic complexities in modern vehicles, the necessity for robust protection against electrical transients has never been more critical. The new TransGuard VT Series MLVs have been meticulously engineered to accommodate extreme conditions typical in automotive environments, boasting impressive operational benchmarks. These components are zinc-oxide-based ceramic semiconductors that ensure reliable performance in various applications, including electric vehicles (EVs), e-bikes, and a range of transportation systems.

The MLVs are capable of withstanding operational temperatures from -55°C to +175°C without any performance derating, maintaining their integrity in the most taxing conditions. They have successfully met rigorous qualification standards, including AEC-Q200, IEC 61000-4-2, and ISO 10605, giving automotive manufacturers confidence in their reliability.

Exceptional Specifications for Versatile Applications

The high-temperature specifications of the MLVs make them ideal for protecting against the electrical volatility caused by motors, radiators, relays, and more. Furthermore, their bidirectional overvoltage protection capabilities obviate the need for discrete MLCCs, optimizing both board space and overall cost. The components are available for a variety of high-temperature automotive applications, boasting impressive ratings such as 56VDC operating voltage and 40VAC, making them apt for both passenger vehicles and commercial applications.

The latest addition to the TransGuard VT Series is equipped to handle jump start voltage scenarios of 48V, including 30-1500A transients with capacitance values from 80 to 2800pF, therefore catering to a wide array of electrical configurations present in forward-thinking vehicle designs.

An Industry Milestone

KYOCERA AVX’s Product Marketing Manager, Perrin Hardee, expressed the company’s excitement about this new product release. According to Hardee, “Our after-expansion TransGuard VT Series MLVs not only provide excellent protection but also allow for reduced component complexity and cost efficiency in automotive design. As the automotive sector continues to innovate, our technologies are essential in overcoming the electrical challenges presented by modern engineering.”

Availability and Further Information

The newly released 48V System VT Series MLVs are currently offered in a variety of EIA chip sizes, including 0805, 1206, 1210, 1812, and 2220, all packaged in user-friendly tape and reel formats. This provides manufacturers a streamlined solution for their production needs while adhering to environmental standards with RoHS compliance.
