B43713A6478M000
TDK EPCOS B43713 screw-terminal capacitor, 4700 uF at 500 V, Ø90 x 145.5 mm, 85 °C with 12,000-hour life and high ripple.
The B43713A6478M000 is a TDK EPCOS B43713 series screw-terminal aluminum electrolytic capacitor rated at 500 V with 4700 uF, in a case of about 90 mm diameter by 145.5 mm long. The B43713 series is a high-ripple, long-life family rated 85 °C with an endurance of 12,000 hours, designed for the DC link of frequency converters and the bulk storage of large power supplies. The screw terminals accept a busbar or heavy cable, so the capacitor carries the high DC-link current without the lead limitations of a PCB part, and its rated ripple current of about 17.5 A at 100 Hz shows the high ripple capability the family provides. The low self-inductance that results from the design helps limit the voltage overshoot of a switching power stage. Mounting is by a clamp or a bottom stud with M5 or M6 threaded terminals, and the capacitor is rugged enough for industrial vibration. Typical uses include the DC link of a motor drive, the bus of a solar or wind converter and the 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 B43713A6478M000 is a workhorse 500 V DC-link part with a long 12,000-hour life and a high ripple rating, which suits large inverters and professional supplies. The 90 mm can carries real thermal mass, but the mounting clamp and the busbar must be planned for the size. Keep the ripple within the rating at the expected case temperature to realize the endurance.

Frequently Asked Questions
What projects suit the B43713A6478M000?
It suits 500 V class inverter DC links, converter buses and UPS bulk storage that need a large capacitance with a very high ripple rating and a long life. The screw terminals accept a busbar, and the 90 x 145.5 mm case mounts with a clamp or bottom stud.
For lower voltage and more capacitance, see the 250 V 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 M5 or M6 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 connection.
