Key Points
• WBG semiconductors like SiC and GaN enable
high-efficiency power conversion but generate
fast switching transitions that significantly
stress surrounding passive components.
• The higher EMI spectrum and thermal load in
WBG systems require capacitors and inductors
with low ESR/ESL, high frequency response,
and thermal resilience.
• Compact, high-density layouts demand low-
profile passives with effective heat dissipation
strategies.
• YAGEO addresses these challenges with Class
I MLCCs, low-ESR polymer capacitors, metal-
composite inductors, and broadband chokes
optimized for GaN and SiC applications.
