B43713E2688M000
TDK EPCOS B43713 screw-terminal capacitor, 6800 uF at 250 V, Ø64.3 x 119.2 mm, 85 °C with 15,000-hour life and high ripple.
The B43713E2688M000 is a TDK EPCOS B43713 series screw-terminal aluminum electrolytic capacitor rated at 250 V with 6800 uF, in a case of about 64.3 mm diameter by 119.2 mm long. The B43713 series is a high-ripple, long-life family rated 85 °C with an endurance of up to 15,000 hours, designed for the DC link of frequency converters and the bulk storage of large power supplies. At this lower 250 V rating the capacitance per can is higher, so a single capacitor provides a large store of energy. 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 14.2 A at 100 Hz shows the high ripple capability. 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 low-voltage motor drive, the bus of a battery or fuel-cell 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 B43713E2688M000 gives a large 6800 uF capacitance at 250 V with a 15,000-hour life, which suits low-voltage high-current buses and battery or fuel-cell converters. The smaller 64 mm can is easier to mount than the 500 V part. As always, size cooling from the ripple and the case temperature, not from the nominal rating.

Frequently Asked Questions
What projects suit the B43713E2688M000?
It suits 250 V class buses that need a large capacitance and a high ripple rating, such as low-voltage motor drives, battery or fuel-cell converters and UPS storage. The 6800 uF in a 64 mm can stores a large amount of energy.
For a higher-voltage bus, see the 500 V version.
How does the low voltage help?
At a lower voltage the capacitance per can is higher, so a single capacitor provides more stored energy, and the case can be smaller. That suits low-voltage high-current buses where the energy is the priority.
Confirm the ripple margin at the low voltage.
