Jianghai CD 130 Series Capacitor
85°C, Very High Capacitance, Screw TerminalDistributor's Insight
FAE Review: For bulk energy storage in a high-power industrial application, the CD 130 is the industry standard. Its screw terminals allow for secure, high-current connections via bus bars, and the large can sizes provide the enormous capacitance needed to stabilize the DC bus in a Variable Frequency Drive (VFD) or large UPS system. While it's an 85°C part, its sheer thermal mass and high ripple capability make it exceptionally durable in real-world industrial cabinets.
Description & Specifications
The CD 130 series represents the pinnacle of bulk energy storage in aluminum electrolytic technology. Designed with robust screw terminals for secure mounting and high current handling, these capacitors form the backbone of DC Bus filtering in the most powerful industrial equipment. Their high capacitance and excellent ripple current ratings ensure a stable DC voltage, which is essential for the proper functioning of inverters and converters.

Frequently Asked Questions (FAQ)
Q: Why is this rated for 85°C instead of 105°C?
A: Large can screw terminal capacitors often have an 85°C rating because their sheer size gives them a large thermal mass, making them slower to heat up. They are used in applications where the main goal is immense capacitance and ripple handling, often in environments with forced air cooling. Jianghai also offers 105°C rated screw terminal series for more extreme temperature applications.
Q: Can multiple screw terminal capacitors be connected in parallel?
A: Yes, absolutely. It is very common practice to connect multiple CD 130 capacitors in parallel using bus bars to create a capacitor bank with the total required capacitance and ripple current capability for a high-power DC bus.
