UCS2G470MHD6

The UCS2G470MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCS series designed for high-reliability power applications. It delivers 47 µF capacitance at a 400 V rating in a compact φ18 × 20 mm can with through-hole radial leads.

Engineered for power-supply and ballast applications, the component combines long endurance at elevated temperature with high ripple-current capability to support demanding DC bias and ripple conditions in industrial and general-purpose electronic equipment.

Key Features

• Capacitance & Voltage: 47 µF capacitance rated at 400 V for energy storage and smoothing on higher-voltage rails.
• High ripple-current capability: Low-frequency ripple current 590 mA (120 Hz) and high-frequency ripple current 1.18 A (100 kHz) to handle substantial AC ripple loads.
• Long endurance: Rated life of 10000 hours at 105°C, providing extended operational reliability under elevated temperature and ripple stress.
• Temperature range: Operational from −40°C to 105°C for broad environmental tolerance.
• Electrical loss and leakage: Tangent of loss angle (tan δ) 0.24 (measured at 20°C, 120 Hz) and measured leakage current 852 µA, enabling predictable performance characteristics for design calculations.
• Package and mounting: Radial lead, polarized can in φ18 × 20 mm size with 7.5 mm lead spacing (±0.5 mm tolerance) for standard through-hole assembly and secure mechanical mounting.
• Compliance & availability: RoHS compliant and listed as mass production with bulk/bag packing options for production procurement.

Typical Applications

• Power Supplies: Bulk smoothing and output filtering on 400 V rails where high ripple current and long life at elevated temperature are required.
• Ballasts and Lighting Drivers: DC link and smoothing capacitor duties in ballast designs, supporting stable operation under ripple and thermal stress.
• Industrial Power Conversion: Energy storage and decoupling in converters and inverters operating in demanding thermal environments.
• General-Purpose Electronics: Use in equipment requiring a polarized, through-hole capacitor with predictable leakage and long endurance.

Unique Advantages

• High-voltage capability: 400 V rating enables use on higher-voltage DC buses without stacking multiple capacitors.
• Designed for ripple-heavy duty: Specified ripple-current ratings at both low and high frequencies reduce thermal stress and extend service life in ripple-intensive circuits.
• Extended high-temperature life: 10000-hour endurance at 105°C provides predictable, long-term performance for thermally demanding installations.
• Compact through-hole form factor: φ18 × 20 mm can and radial leads provide a space-efficient, mechanically robust solution for through-hole assemblies.
• Measured electrical parameters: Specified tan δ and leakage current simplify thermal and leakage budgeting during design and validation.
• Production-ready supply: Mass-production status and bulk/bag packaging support consistent procurement for volume manufacturing.
