48V ADAS & Infotainment

Next generation 48V zonal automotive systems for ADAS and infotainment require highly efficient and reliable power management to support increasing processing demands, advanced sensing technologies, and connected vehicle features. These applications can utilize wide-input voltage ranges on a 48V battery, up to 70V. Power architectures used in zonal configuration can vary from wide input buck-boost converters, intermediate buck or boost converters, or point-of-load multi-phase buck converters. High-efficiency DC-DC conversion delivers stable power to cameras, radar, displays, networking modules, and centralized computing systems used throughout the vehicle. As vehicle systems continue evolving toward Centralized Computer from Domain Controllers and Zonal Architecture designs, power systems must support higher power density, reduced wire harness complexity, and improved thermal performance. 

Capacitors to support 48V ADAS & Infotainment should have the following characteristics:

  • High Ripple Current
  • Reliable Operational Life
  • Wide Capacitance

Features

AEC-Q200 Qualification
Many of our series are AEC-Q200 compliant, meeting the automotive industry’s stringent stress test requirements for passive components.
Compact Size
We produce miniature and surface-mount capacitors to meet space-saving requirements in densely packed automotive PCBs.
High Ripple Current
Many of our capacitors can support systems with high ripple demands, such as DC-DC converters, onboard chargers, and ECUs. These include our conductive polymer aluminum solid electrolytic capacitors and conductive polymer hybrid aluminum electrolytic capacitors.
High Temperature Resistance
Heat resistance is essential as electrical components are exposed to the high-temperature environments inside of modern electric vehicle powertrains, including motors, traction inverters, and battery packs. 
Low ESR/Low Impedance
48V ADAS and infotainment systems require fast and stable power delivery to support advanced processors, sensors, networking modules, and high-speed data communication. Nichicon low impedance and low ESR capacitors help reduce power loss, improve voltage stability, and support high-frequency switching power circuits used in modern automotive.
Vibration Resistance
We offer capacitors designed to withstand high vibration environments, ideal for under-hood and chassis-mounted electronics.
