Key Points
• The shift from 400V to 800V architectures
allows for faster charging and higher
efficiency but places intense electrical and
thermal stress on capacitors and magnetics.
• Common-mode chokes must now absorb
more EMI load due to Y-capacitance
restrictions and require broadband
performance without increased thermal or
insertion loss.
• Compact traction inverters and converters
demand passives that endure high ripple
current, rapid thermal cycling, and
constrained cooling environments.
• YAGEO supports 800V powertrains with
high-voltage film capacitors, broadband
chokes, precision MLCCs and resistors, and
simulation tools.
