ERWQ351LGC152MC65U
Nippon Chemi-Con RWQ screw-terminal capacitor, 1500 uF at 350 V, Ø50 x 65 mm, 85 °C with high ripple for inverter DC links and UPS.
The ERWQ351LGC152MC65U is a Nippon Chemi-Con RWQ series screw-terminal aluminum electrolytic capacitor rated at 350 V with 1500 uF, in a case of about 50 mm diameter by 65 mm long. The RWQ series is downsized with a high ripple current rating compared with the earlier RWE series, and it is designed for inverter and power-conversion DC links where a large capacitance must smooth a high-ripple current. A screw terminal accepts a busbar or heavy cable, so the capacitor handles the high current of the DC link without the lead limitations of a PCB part, and the large can provides a substantial thermal mass that helps dissipate the ripple heating. The capacitor is rated 85 °C with a 2000-hour endurance at the rated ripple current, and the operating temperature range is -40 °C to +85 °C. It mounts with a clamp or a bottom stud and is rugged enough for industrial vibration. Typical uses include the DC link of a motor drive, the bus of a solar or storage inverter and the bulk storage of a UPS. Every capacitor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team can confirm the ripple margin and the lifetime for your operating conditions.
FAE Professional Review
The ERWQ351LGC152MC65U is a workhorse DC-link part for 350 V class inverters, and its downsized high-ripple design lets you use fewer cans for the same energy. Screw terminals make the busbar connection straightforward, but plan the clamp and the clearance around the can, and keep the ripple within the rating for the expected case temperature so the 2000-hour endurance holds.

Frequently Asked Questions
What projects suit the ERWQ351LGC152MC65U?
It suits 350 V class inverter DC links, motor-drive buses and UPS bulk storage that need a large capacitance with a high ripple rating. The screw terminal accepts a busbar or heavy cable, and the 50 x 65 mm case fits a clamp mount.
For more capacitance, use the taller 1800 uF version.
How do I mount and connect it?
Mount the capacitor with a clamp or a bottom stud, and connect the busbar or cable to the screw terminal with the specified torque. Keep the mounting clear of other hot components and allow airflow, because the case temperature sets the lifetime.
Our FAE team can review the mounting and the connection.
