The document describes the applications, features, and construction of long-life grade capacitors, as well as the specifications and characteristics of the B43456 and B43458 models.
The B43456 and B43458 are long‑life grade aluminum electrolytic capacitors designed for frequency converters, professional power supplies and uninterruptible power supplies. They feature an all‑welded construction, high ripple‑current capability and optional low‑inductance or base‑cooling designs.
The datasheet lists rated voltages of 350‑450 VDC, capacitance values from 1 000 µF to 18 000 µF, ESR and ripple‑current limits, dimensional drawings for various diameters, and mounting options such as ring‑clip, clamp or threaded stud. Technical tables also include ordering codes, useful‑life graphs and frequency characteristics.
| Rated voltage (UR) | 350‑450 VDC |
|---|---|
| Capacitance range | 1 000‑18 000 µF |
| Self‑inductance (ESL) | ≈ 20 nH |
They are intended for frequency converters, professional power supplies and uninterruptible power supplies.
The rated voltage is between 350 VDC and 450 VDC.
Mounting can be done with ring‑clip or clamp, or with a threaded stud; screw terminals with UNF threads are also available on request.
