The ZC and ZK series are surface-mount conductive polymer hybrid aluminum electrolytic capacitors designed for high-temperature, lead-free reflow assembly. Both families target designs that need low impedance at high switching frequencies and stable capacitance behavior over temperature, while keeping the footprint compact.
The ZC series is the higher-voltage option, supporting rated voltages up to 80V, which makes it a good fit for 48V systems, distributed industrial rails, and automotive subsystems where voltage margin is needed.
The ZK series focuses on higher capacitance and ripple current versus ZC, while keeping the same 4000 hours at 125°C endurance target. It is aimed at lower-voltage rails, 25V to 35V, where bulk energy storage and ripple handling are the priority.
