LE220M450I250A
CapXon LE ultra-long-life radial capacitor, 22 uF at 450 V, Ø13 x 25 mm, 105 °C with 12000-hour endurance.
The LE220M450I250A is a CapXon LE series radial leaded aluminum electrolytic capacitor rated at 450 V with 22 uF, in a case of about 13 mm diameter by 25 mm long. The LE series is an ultra-long-life 105 °C radial range rated 12000 hours (and up to 20000 hours for some sizes), which suits equipment that must run for many years with little servicing, such as solar inverters, industrial power conversion and long-life lighting drivers. A radial leaded capacitor mounts directly on the printed circuit board with two straight leads, so the footprint stays compact even at this voltage, and the 450 V rating holds a rectified high-voltage aux rail with margin. The 22 uF is a small but useful high-voltage value, common as a primary-side auxiliary capacitor or a snubber-adjacent bulk part where a low leakage and a long life matter more than a large capacitance. The operating temperature range is -40 °C to +105 °C. Typical uses include the auxiliary high-voltage rail of a solar or storage inverter, the primary-side support of a long-life supply and the smoothing of an industrial converter. Every capacitor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you size the capacitance and ripple and estimate the lifetime from the case temperature.
FAE Professional Review
The LE220M450I250A is the ultra-long-life choice in the 450 V radial class, with a 12000-hour endurance at 105 °C that is ideal for solar, industrial and lighting equipment that cannot be serviced often. The 22 uF is a modest value, so use it where long life and low leakage matter rather than for bulk energy. Keep the ripple within the rating and the case cool to realize the full life.

Frequently Asked Questions
What projects suit the LE220M450I250A?
It suits high-voltage auxiliary rails that must run for many years, such as solar and storage inverters, long-life supplies and industrial converters, where the 12000-hour endurance at 105 °C is a real advantage. The 22 uF is a modest high-voltage value for long life and low leakage.
Keep the ripple within the rating and the case cool.
How do I realize the long life?
The 12000-hour endurance is specified at 105 °C and rated ripple; keeping the case cooler or the ripple lower extends the life further, because electrolytic lifetime roughly doubles for every 10 °C reduction in core temperature. Space the capacitor for airflow and keep it away from hot components.
Our FAE team can estimate the lifetime at your conditions.
