A comparable wet aluminum part at the same frequency would run higher losses and derate harder in a switch-mode supply output stage. The ripple current spec of 3.3 A @ 100 kHz tells you what it can absorb in a DC-DC converter output or input filter without baking the capacitor internally. If the converter runs at a fixed switching frequency, match that frequency to the ripple current measurement condition — the rating drops at higher frequencies if the ESR starts to dominate the impedance budget. ## Thermal margin — 15,000 hrs at 105°C and the -55°C floor 15,000 hours at 105°C rated lifetime means this part is suited for industrial power supplies and motor drive enclosures where ambient temperatures routinely push 80–90°C. At lower operating temperatures the actual lifetime extends significantly — the Arrhenius relationship roughly doubles life for every 10°C drop. If the application runs cool, the capacitor will outlast the equipment. The -55°C cold floor means it survives cold-start transients in outdoor or transportation-equipment applications — a DC bus that charges through the capacitor on a cold boot at -40°C sees the same ESR and capacitance it would at room temperature, with no cold-start derating concern in the spec. ## SMD package — rework bake-out and board-level handling The 8 mm diameter radial can with a seated height of 10.3 mm is a mid-size SMD — the 8.3 mm x 8.3 mm land pattern gives enough pad overlap for reliable reflow but also enough clearance around the barrel for hot-air rework. Before rework, check the moisture sensitivity rating — polymer capacitors in this form factor are typically MSL 3, but baking at 125°C for the required dwell time before removal prevents package cracking on the adjacent reflow cycle. Supplied on Tape & Reel and Cut Tape — Cut Tape is often more practical for rework and prototyping where you need just a handful of units without unspooling a full reel. No official successor is listed in the ledger. For a polymer aluminum part at this voltage and capacitance, the direct cross-reference is most likely in the same NPCAP-PXG series footprint — confirm the substitute matches the ESR, ripple, and dimensions before committing to a BOM change.","metaTitle":"APXG250ARA101MHA0G United Chemi-Con Polymer Capacitor","metaDescription":"United Chemi-Con NPCAP™-PXG polymer aluminum capacitor, 100 µF 25 V rated, 24 mΩ ESR, 3.3 A ripple @ 100 kHz, -55°C to 105°C.
