What Do UL and CQC Certifications Mean For Safety Capacitors From Film Capacitor Factories
2026-10-30 09:58:00
safety capacitor certification including UL and CQC is the core qualification for safety film capacitors to be used in mains EMI filtering. These certifications are not simple product quality marks, but proof that the capacitor has passed strict safety tests according to unified international standards.
UL certification for safety capacitor: It is mainly for North American market access, tested according to UL 1414 and UL 1283 standards, evaluating surge resistance, flame retardant performance and safe failure mode. Products with UL marks can help terminal products pass local safety inspection smoothly.
CQC certification for safety capacitor: It is the mandatory certification for the Chinese market, implemented based on IEC 60384-14. It limits leakage current, flame retardancy and overvoltage failure characteristics. Without valid CQC certification, the end product cannot be sold in China.
weidy safety capacitor reminds purchasers that certification files must be checked together with the capacitor body marks. Expired or inconsistent certificates will lead to the failure of the whole machine safety test, and the certification of ordinary CBB capacitors cannot replace safety capacitor certification.
