Frequently Asked Questions

What is the typical application solution of Jianghai capacitors in industrial inverters?

Jianghai provides complete capacitor solutions for industrial inverters: 1) DC-Link capacitors: CD139 series screw terminal aluminum electrolytic capacitors (e.g., 10000uF/450V) or DC-Link film capacitors (e.g., 100uF/800V), capacitance selected based on power, voltage rating 450V-800V

2) Snubber capacitors: 0.47uF/1200V film capacitors to suppress IGBT switching spikes

3) Control power capacitors: CD11 series small aluminum electrolytic capacitors (e.g., 1000uF/25V). Complete solutions include BOM list, reference design, and FAE technical support.

What are the features of Jianghai photovoltaic inverter capacitor solutions?

Jianghai photovoltaic inverter capacitor solution features: 1) Long lifespan design: Film capacitors lifespan up to 100,000 hours, meeting PV system 20-25 year service requirements

2) High reliability: Self-healing characteristics, low ESR, wide temperature range

3) High efficiency: Low loss design, improving system overall efficiency by 0.5-1%

4) Compact: Compared to aluminum electrolytic capacitors, film capacitors are smaller and lighter

5) Environmental-friendly: No electrolyte, no leakage risk. Recommended solutions: 10-20kW single-phase inverters use 100uF/800V DC-Link capacitors, 20-50kW three-phase inverters use 150-300uF/800V capacitors.
