Low-ESR polymer construction for switching-rail decoupling
The APXG200ARA151MF80G: United Chemi-Con builds this part around a conductive polymer cathode — the chemistry that cuts ESR to 25mΩ compared to a wet electrolytic of the same case size, which means the ripple current rating of 3.2 A at 100 kHz is a real switching-frequency capability, not a thermal headroom calculation. At 150 µF and 20 V in a 6.30 mm diameter package, this sits squarely in the sweet spot for bulk decoupling on medium-current point-of-load converters and input filters on boards where you need capacitance density without the derating risk of a ceramic.
Lifetime and temperature grade for industrial power paths
The 15,000-hour lifetime at 105 °C operating temperature tells you this is rated for sustained thermal stress in enclosed equipment — not a short-duty consumer product. The -55 °C cold start capability covers outdoor or vehicle-adjacent deployments without a warm-up window. Surface-mount termination on a radial can means it reflow-solders like a standard SMD — the 0.260-inch square land pad lands cleanly on a 6.60 mm by 6.60 mm footprint without specialised adapter hardware.
