Industrial Aluminum Electrolytic Capacitors | Series Overview
What Are Aluminum Electrolytic Capacitors?
Aluminum electrolytic capacitors are polarized capacitors that use an aluminum oxide dielectric layer to achieve high capacitance per volume. They are widely used in AC-DC power supplies, DC-DC converters, industrial SMPS, inverters, motor drives, and renewable energy systems.
Compared with ceramic and film capacitors, aluminum electrolytic capacitors provide:
- Higher capacitance values (µF to mF range)
- Cost-effective bulk energy storage
- Strong ripple current capability
- Wide voltage range for industrial systems
jb offers a complete portfolio of aluminum electrolytic capacitors engineered for industrial SMPS, DC-DC converters, inverters, motor drives, LED drivers, and power electronics systems.
