Capacitor 470µF, 400V (model DINZHHENGYIN) — Size 30 x 50 mm — Pack: 1 piece What this capacitor does and why you need it Stabilizes the DC bus in high-voltage power electronics to improve inverter and converter reliability. Smooths voltage and stores energy to supply brief current peaks, reducing voltage sag and ripple in demanding circuits. Compact footprint (30 x 50 mm) for installations where space is limited without sacrificing performance. Key benefits — how it solves problems and stands out Reliable DC bus support: helps maintain steady voltage under transient loads to protect downstream electronics and improve system response. Peak current handling: supplies short bursts of energy for operations like welding pulses or motor startup, avoiding supply dips. Space-efficient design: small size makes it suitable for tight enclosures and compact assemblies. Built for continuous use: designed for robust operation in demanding environments common to power conversion equipment. Compatibility and common applications Ideal for point welding machines and inverter frequency converters. Suitable for other high-voltage DC link applications and power supplies where a 400V rated smoothing/energy storage capacitor is required. Practical use scenarios Welding equipment: smooths the DC bus to ensure dependable peak current during weld cycles and reduce weld variability. Inverter-driven motors and CNC drives: stabilizes the inverter input to improve motor performance and protect control electronics during transient loads. High-voltage power supplies and test benches: reduces ripple and provides short-term energy storage for more consistent output during tests and measurements.
