B41456 / B41458 are long-life grade capacitors from DELIXI. They are features with high reliability, high ripple current capability, all-welded construction ensures reliable electrical contact and so on.
The handbook describes EPCOS B41456 and B41458 capacitors with screw‑terminal connections, intended for general industrial electronics and switch‑mode power supplies. It highlights high reliability, high ripple‑current capability and an all‑welded construction, with a low‑inductance version available.
Technical data include rated voltage ranges, capacitance values, self‑inductance, ESR limits, mechanical dimensions, useful‑life expectations and recommended mounting hardware. Ordering codes and accessories such as ring clips, clamps and screws are also listed.
| Rated voltage | 16‑100 VDC |
|---|---|
| Self‑inductance (standard) | ≈ 20 nH |
| Useful life at 85 °C | > 12 000 h |
The capacitors are offered with rated voltages of 16 V, 25 V, 40 V, 63 V and 100 V DC.
The standard design has a self‑inductance of approximately 20 nH.
At 85 °C the capacitor is rated for more than 12 000 hours of operation under the specified ripple‑current conditions.
