EPCOS B43458-S0338-M3 Aluminum Electrolytic Capacitor: Essential Component for Industrial Automation Systems
On this page
One EPCOS B43458-S0338-M3 screw-terminal capacitor is documented in this delivery dated 27 February 2026. The can prints 3300 µF (M), 430 V and 09.21S. Three photographs show the identification, the positive-polarity stripe and the two screw terminals.
Identification and delivery details
The black sleeve carries a clear EPCOS logo and the complete B43458-S0338-M3 designation. A grey stripe with repeated plus signs runs up the opposite face and reaches the terminal end. The top view shows two terminals fitted with screws and washers, plus a separate small circular feature in the insulating top. A pale protective piece covers the opposite-end projection.
The stock note describes one new capacitor with a one-year warranty. It records a 0.5 kg weight field. No scale or dimensions are shown, so that figure remains a record value. The 09.21S string is reported as a can marking without assigning a manufacturing or expiry date.
The photographs establish the printed capacitance and voltage, the terminal form and polarity marking. They do not contain a measured capacitance, ESR or leakage result. The former description's lifetime and ESR figures are not retained because this image set and stock note do not substantiate them.

Matching this part
Match the entire B43458-S0338-M3 designation, capacitance and voltage with the removed capacitor. Send its terminal spacing, can dimensions and mounting arrangement. Similar screw-terminal capacitors can differ mechanically even when the two headline ratings agree.
Before specifying an offered unit, confirm the equipment's required ripple-current, temperature and service-life criteria against the manufacturer's data for that exact part. The photographed plus stripe is useful for orientation; the gallery does not show a wired installation or demonstrate operation under load.
