Infineon Capacitor 4700UF 160V ITELCOND – High-Capacitance Screw Terminal Industrial Electrolytic Capacitor
The Infineon Capacitor 4700UF 160V ITELCOND (frequently supplied alongside Infineon power semiconductor stacks and IGBT drive assemblies) is a heavy-duty, screw-terminal aluminum electrolytic capacitor manufactured by Itelcond. Designed for high-ripple-current filtering and energy storage in intermediate DC-link circuits, the Infineon Capacitor 4700UF 160V ITELCOND delivers a 4700 µF capacitance rating with a 160 VDC continuous operating limit.
As shown in the product image, the capacitor features a cylindrical aluminum casing encased in an insulating PVC sleeve with top-mounted M5 screw terminals. Built with high-purity aluminum foil and long-life electrolytic chemistry, it provides reliable performance in industrial power converters, motor drives, and switch-mode power supplies (SMPS) subject to rapid charge/discharge cycles.

Installation Guidelines and Best Practices
Safety Warning: Ensure the capacitor is fully discharged through a high-wattage bleeder resistor before handling terminals. Large electrolytic capacitors can retain dangerous electrical charges long after power isolation.
Respect Voltage Polarity: Pay strict attention to the positive (+) and negative (–) terminal markings printed on the top deck to prevent catastrophic dielectric breakdown.
Torque Specifications: Torque terminal connection bolts to maximum recommended values (2.0 to 2.5 N.m) using a torque wrench to ensure low contact resistance on busbar joints.
Thermal Positioning: Mount capacitors vertically with safety vent relief clearance, positioned away from heat-generating components like braking resistors or power transistors.
Industrial Durability and Power Electronics Integration
Beyond basic filtering tasks, implementing a Capacitor 4700UF 160V ITELCOND is highly beneficial for safeguarding complex industrial motor drives, induction heating power supplies, arc welding machinery, and switch-mode power supplies (SMPS).
