Polymer chemistry gives this part lower ESR than a comparable tantalum or wet-aluminum part of the same case size, which is what makes it useful as a local decoupling or rail-smoothing element close to a load IC — the 2 V rating suits 1.8 V and lower rail points where headroom above 200 mV is needed. ## ESR, ripple current, and switching performance The 5.6 A ripple current rating at 100 kHz sets the current-handling ceiling for the switched node or output filter position — above this current the capacitor self-heats past the rated temperature band, accelerating the 2000-hour lifetime at 105°C. At 105°C operating ambient the 2000-hour rated lifetime is appropriate for consumer and general-purpose applications; the -55°C lower limit covers cold-start and outdoor-equipment temperature extremes — a MIL or automotive-grade polycap would be specified differently for long-life mission profiles. ## Footprint, land pattern, and board integration The 0.287-inch by 0.169-inch (7.30 mm × 4.30 mm) land pattern matches the industry-standard 2917/7343 metric SMD land — the surface mount land size in the spec matches the component body exactly, so the PCB pad geometry follows the datasheet footprint without additional scaling. The EEF-CX0D271XR is listed Active by Panasonic Electronic Components; no official successor or cross-reference appears in the manufacturer record — the SP-Cap CX base product number (EEF-CX) is the series anchor if a parametric replacement in the same family is required.","metaTitle":"Panasonic EEF-CX0D271XR Polymer Capacitor, 270 µF 2 V","metaDescription":"Panasonic SP-Cap CX polymer capacitor, 270 µF 6.3 V 12 mΩ ESR, 5.6 A ripple @ 100 kHz, -55°C to 105°C, 2917 SMD.
