TDK SMD Hybrid Polymer Capacitors
TDK SMD hybrid polymer capacitors set a new standard for surface mount technology in demanding automotive, industrial, and ICT applications. Featuring an innovative hybrid electrolyte that combines conductive polymer with liquid electrolyte, these capacitors offer ultra-low equivalent series resistance (ESR), exceptionally high ripple current capability, and robust thermal and vibration endurance.
Designed for miniaturized integration, TDK hybrid polymer SMD capacitors deliver outstanding power density and high reliability across temperatures up to +150°C, making them a first choice for next-generation electronics requiring compact, long-life, and high-performance energy storage components.
