Oil‑free dry‑type DC capacitor, DC rated voltage up to 3400V, rated RMS current up to 800A, max capacitance 7.4 mF, self‑healing metallized polypropylene film, long‑life oil‑free resin encapsulated power‑electronic capacitor.
This PDF product flyer serves for component selection, power‑electronic project evaluation and tender reference. The capacitor complies with IEC 61071, the valid international standard for power‑electronic capacitors.
It adopts self‑healing metallized polypropylene dielectric and polyurethane resin oil‑free filling with zero‑liquid‑leakage risk, featuring gradual capacity degradation under fault conditions, failure rate below 50 FIT and service life exceeding 345 000 hours.
This datasheet records dissipation factor, low self‑inductance, terminal‑to‑casing withstand voltage, creepage & flashover clearance dimensions, operating and storage temperature range, high‑strength aluminum‑alloy housing, horizontal‑or‑vertical mounting options, and combined safety protection of self‑healing function plus fuse segmentation, without requiring grading resistors.
Custom‑manufacturing solutions covering design, assembly and factory test are available for high‑capacity and harsh‑condition power‑electronic scenarios. Please contact us for complete dimension drawings and full set of type‑test reports.
FIT represents failure probability per billion component‑hours, it is a key reliability index to evaluate long‑term running stability of capacitor components. Please contact us for reliability‑test records.
The dielectric can self‑repair tiny internal breakdown points; together with fuse‑segmentation protection, it achieves gradual capacity degradation under faults instead of sudden catastrophic failure. Please contact us for principle introduction.
Oil‑free resin filling eliminates liquid leakage hazard, improves environmental safety and simplifies maintenance for power‑electronic equipment. Please contact us for comparative performance data.
