At that measurement frequency the part delivers 3.65 A of ripple current capability. For a 20 V rail feeding a point-of-load converter, that ripple current rating determines whether the cap sits comfortably inside the switching loop or whether you are pushing it at the thermal limit. A polymer construction handles the ripple-generated self-heating better than a standard electrolytic because the conductivity of the electrolyte is inherently higher — which is the whole point of the polymer type. ## Thermal headroom and the 15,000-hour lifetime The 15,000-hour rating at 105 °C is the derating anchor for the NPCAP-PXG series. At full rated ripple the internal temperature rise above ambient can be significant, so the 105 °C operating ceiling gives you a defined thermal budget to work within — if your board runs 85 °C ambient with modest airflow, you have roughly 20 °C of margin before approaching the rated temperature, which is a comfortable position for a bulk-decoupling role. The -55 to 105 °C temperature range covers the industrial and automotive ambient envelope. For a consumer board running at 85 °C max ambient, the upper limit is not a concern; for a motor-drive inverter housing or outdoor enclosure, the full range matters and the 105 °C ceiling is the limiting factor — not the low end. ## Footprint and board integration The recommended land pattern is 0.406 in by 0.406 in (10.30 mm × 10.30 mm) — a standard pad size for this case diameter that gives the solder joint a compliant interface without requiring a custom footprint. Tape-and-reel packaging with cut-tape option covers both production volumes and prototyping runs. ## Active sourcing posture The part is listed as Active by United Chemi-Con, which means it is a current-production order code with a normal distribution pipeline.","metaTitle":"United Chemi-Con APXG200ARA391MJ80G","metaDescription":"United Chemi-Con APXG200ARA391MJ80G — 390 µF, 20 V rated, 22 mΩ ESR polymer capacitor in a 10 mm SMD can. 3.65 A ripple at 100 kHz, 15,000 hr @ 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Specialty Capacitors"],"specifications":{"Mfr":"United Chemi-Con","Type":"Polymer","Series":"NPCAP™-PXG","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Tolerance":"±20%","Capacitance":"390 µF","Applications":"General Purpose","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"Radial, Can - SMD","Product Status":"Active","Voltage - Rated":"20 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"15000 Hrs @ 105°C","Size / Dimension":"0.394\\\" Dia (10.00mm)","Height - Seated (Max)":"0.315\\\" (8.00mm)","Operating Temperature":"-55°C~105°C","Surface Mount Land Size":"0.406\\\" L x 0.406\\\" W (10.30mm x 10.30mm)","Ripple Current @ High Frequency":"3.65 A @ 100 kHz","ESR (Equivalent Series Resistance)":"22mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/02bc78cd4fb3a155d68a201dc50bc4a6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What type of capacitor is the APXG200ARA391MJ80G?","answer":"It is a solid-polymer aluminum electrolytic capacitor — the NPCAP™-PXG series uses a conductive polymer electrolyte rather than a wet electrolyte, which gives it lower ESR and better ripple-current handling than a standard aluminum electrolytic of the same capacitance and voltage rating."},{"question":"Is the APXG200ARA391MJ80G still active and available?","answer":"United Chemi-Con lists it as Active."},{"question":"What voltage and capacitance does the APXG200ARA391MJ80G offer?","answer":"Rated 20 V with 390 µF capacitance at ±20% tolerance.
