Bourns Battery/Capacitor Backup Unit Applications
Bourns Battery Backup Unit (BBU) and Capacitor Backup Unit (CBU) Applications feature components essential for DC/DC auxiliary power, current sensing, and temperature sensing applications in BBU and CBU architectures. BBUs deliver uninterrupted power to servers and networking equipment during power disturbances, while CBUs provide instantaneous energy during extreme power spikes, such as when large GPU clusters transition from idle to full load in milliseconds. The Bourns portfolio for BBU and CBU applications includes sensors, fuses, diodes, potentiometers, inductors, varistors, thermistors, and resistors. These Bourns products enable safe, reliable, and intelligent energy storage solutions for AI-driven data centers.
