UPT2E471MRD

The UPT2E471MRD is a radial-lead aluminum electrolytic capacitor with 470 µF capacitance and a 250 V rated voltage. It is part of Nichicon’s UPT series, designed for miniature sizing with high ripple current capability and long-life endurance for demanding power applications.

Key attributes include a wide operating temperature range from −40°C to +105°C, rated endurance of 5000 hours at 105°C, and RoHS compliance. Status: End Of Life.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 250 V and tolerance of −20% to +20%.
• Radial Lead Package — Polarized radial-lead, can-style package sized φ22 × 50 mm with 10 mm lead spacing (±0.5 mm), suited for through-hole mounting.
• High Ripple Current — Low-frequency ripple current of 1.45 A at 120 Hz and high-frequency ripple current of 2.32 A at 10 kHz, supporting circuits with substantial AC ripple demands.
• Long Life Endurance — Specified for 5000 hours at 105°C under rated DC bias plus rated ripple current; capacitance change remains within ±20% after endurance testing.
• Low Dissipation Factor — tanδ (DF) of 0.12 measured at 20°C, 120 Hz, helping maintain stable performance in AC conditions.
• Leakage Current — Measured leakage current specified as 7060 µA for this part after 2 minutes at rated voltage and 20°C.
• Environmental Compliance — RoHS compliant.
• Packaging — Supplied in bulk with no terminal forming or in bag packing, for flexible assembly handling.

Typical Applications

• Ballast and Lighting Electronics — Suitable for ballast applications where the UPT series’ high ripple current capability is beneficial.
• Power Supply Filtering — Used for bulk filtering and smoothing in 250 V DC circuits requiring 470 µF capacitance and long operational life.
• General-Purpose High-Voltage Circuits — Fits general-purpose electronic designs that need a polarized aluminum electrolytic capacitor in a compact radial can package.

Unique Advantages

• High Ripple Handling: Rated ripple currents of 1.45 A (120 Hz) and 2.32 A (10 kHz) allow reliable operation under substantial AC superposition.
• Extended Operational Life: 5000 hours endurance at 105°C under rated conditions reduces replacement frequency in long-life designs.
• Compact Radial Form Factor: φ22 × 50 mm can with 10 mm lead spacing provides a space-efficient through-hole solution for power electronics.
• Stable Loss Characteristics: Low tanδ (0.12 at 120 Hz, 20°C) supports predictable dissipation behavior in AC environments.
• Regulatory Compliance: RoHS-compliant construction supports environmental and regulatory requirements for many markets.
