560 µF polymer SMD — the NPCAP-PXG series brief
The APXG160ARA561MHA0G is a 560 µF polymer aluminum electrolytic capacitor rated 16 V, housed in a radial SMD can — United Chemi-Con's NPCAP-PXG series. Polymer construction gives it a 18 mΩ ESR versus the tens or hundreds of milliohms a conventional wet-electrolyte part of the same capacitance would carry. The 18 mΩ ESR directly determines the ripple current the capacitor can handle without overheating. At 100 kHz the part is rated 3.9 A ripple — a figure that would require a substantially larger case size in a standard electrolytic to achieve.
Lifetime and thermal margin at 105 °C
Rated lifetime is 15000 hours at 105 °C, which is the thermal stress ceiling for this part. The operating temperature window spans -55 °C to 105 °C — the lower bound covers cold-start and field-deployment environments; the upper bound is the sustained case temperature the capacitor tolerates while meeting its full ripple-current rating. At room-temperature operation the effective lifetime extends well beyond the 105 °C rated figure, per the usual Arrhenius derating rule-of-thumb — a typical power supply running at 45 °C ambient inside an enclosure sees a lifetime in the tens of thousands of hours. The 105 °C rating matters most in thermally constrained slots: point-of-load converters near hot processors, or enclosed power modules with limited airflow.
SMD radial can footprint and land pattern
The body is 8.00 mm diameter with a seated height of 10.30 mm. The recommended surface-mount land pattern is 8.30 mm × 8.30 mm — the 0.15 mm per side margin over the 8.00 mm body diameter accounts for solder fillet and tombstoning risk on reflow. Confirm your paste stencil aperture and reflow profile against the manufacturer recommended solder reflow conditions before committing to the layout. The reel quantity matters for high-volume assembly; check the per-reel count before scheduling the BOM run.
