Series mapping
- CDE 941C / 942C / 943C — ultra-high dV/dt polypropylene → C451 – C458 family: 100 – 3,000 V, 0.001 – 33 µF, −55 °C to +105 °C.
- CDE 930 / 932 / 935 / 950 / 936C — pulse and energy-storage film types → matched within the C451 – C458 and high-voltage families.
- CDE DPP / DPPM / DPM — DC and pulse polypropylene → matched within the film range, with the DC-link and pulse series covering the higher current duties.
The parameter that decides the match
In high dV/dt duty the limiting factor is not the capacitance value but the repetitive pulse capability: peak current per microsecond, ripple current and internal temperature rise. Send the CDE part number together with the pulse or ripple duty it sees — we match on that basis rather than on capacitance alone.
Also relevant
If the original part is a high-temperature mica type rather than a film capacitor, the CV series is the corresponding route — see mica capacitors and the Eurofarad HT replacement page.
| CDE family | Type | Our replacement route |
|---|
| 941C / 942C / 943C | Ultra-high dV/dt polypropylene | C451 – C458: 100 – 3,000 V, 0.001 – 33 µF |
| 930 / 932 / 935 / 950 / 936C | Pulse and energy-storage film | C451 – C458 and high-voltage families |
| DPP / DPPM / DPM | DC and pulse polypropylene | Film range; DC-link (C480/C481) for high current |
| MLP (mica) | High-temperature mica | CV series: −55…+155 °C, up to +250 °C special |
Frequently asked questions
Can your capacitors replace CDE 941C exactly?
The C451 – C458 family covers the same ultra-high dV/dt duty and the equivalent voltage and capacitance ranges. Send the part number and the pulse duty for a confirmed match.
Do you have equivalents for CDE military-grade mica types?
Where the original is a high-temperature mica part, the CV series is the corresponding route. Note that MIL-qualified (QPL) part numbers carry certification requirements that we do not claim to meet; for those programs we can supply as a documented second source only.
What documentation comes with a replacement?
The technical specification for the part number, the dimensional drawing, and batch acceptance test data on request.
