UPT2G470MHD

The UPT2G470MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPT series designed for high-ripple, long-life applications. It is a miniature, polarized electrolytic capacitor specified at 47 µF and 400 V with a compact φ12.5 × 35.5 mm can and 5 mm lead spacing.

Engineered for general-purpose and ballast use, the device delivers targeted performance for high-voltage power circuitry where sustained ripple handling, a wide temperature range, and 5000-hour endurance at elevated temperature are required.

Key Features

• Rated Capacitance and Voltage — 47 µF nominal capacitance at a 400 V rated voltage for high-voltage DC applications.
• High Ripple Current Capability — Low-frequency ripple current 370 mA (120 Hz) and high-frequency ripple current 592 mA (10 kHz), enabling reliable AC and pulsed-load performance.
• Long Endurance — 5000 hours life rating at 105°C under DC bias plus rated ripple current, supporting extended service in demanding environments.
• Temperature Range — Operates from −40°C to +105°C to cover a broad set of industrial ambient conditions.
• Loss Characteristics — tan δ 0.15 (measured at 20°C, 120 Hz) to help characterize dissipation for thermal and circuit design.
• Leakage Current — Specified leakage current of 1138 µA (after 2 minutes at 20°C), useful for predicting standby and leakage-related behavior in designs.
• Compact Radial Package — φ12.5 × 35.5 mm aluminum can, radial lead mounting and 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Lighting Ballasts — Suited for ballast applications that require high ripple current handling at elevated voltage.
• General-Purpose Power Circuits — Bulk filtering and energy storage in high-voltage DC circuits where 400 V rating and 47 µF capacitance are required.
• High-Voltage Radial Designs — Through-hole assemblies requiring a compact radial electrolytic with defined lead spacing and robust endurance at 105°C.

Unique Advantages

• Designed for High Ripple Environments — Specified ripple currents at both 120 Hz and 10 kHz let designers size capacitive smoothing for AC and high-frequency ripple conditions.
• Long-Term Thermal Reliability — 5000-hour endurance at 105°C provides predictable aging and performance retention in elevated-temperature applications.
• Clear Electrical Characterization — Specified tan δ and leakage current figures enable accurate loss and leakage budgeting in power designs.
• Compact, Through-Hole Form Factor — φ12.5 × 35.5 mm can and 5 mm lead spacing simplify placement in legacy and industrial PCBs that require radial components.
• RoHS Compliance — Meets RoHS requirements for environmental and regulatory consistency in global production.
