UPJ2F4R7MPD

The UPJ2F4R7MPD is a radial-lead aluminum electrolytic capacitor offering 4.7 µF capacitance at a 315 V rating. It is built on Nichicon’s UPJ series low-impedance architecture and is intended for general-purpose and power supply applications where high-voltage handling and stable performance are required.

This part combines a compact φ10 × 20 mm can, polarization for DC circuits, and endurance characteristics suitable for sustained operation up to 105°C. Key electrical characteristics include controlled loss tangent and defined ripple and leakage figures for predictable behavior in power circuits.

Key Features

• Capacitance & tolerance — 4.7 µF nominal capacitance with tolerance of −20% to +20% for predictable decoupling and smoothing.
• High voltage rating — Rated voltage 315 V suitable for higher-voltage DC rails and power circuits where elevated working voltage is required.
• Low-loss characteristic — Tangent of loss angle (tanδ) 0.2 measured at 20°C, 120 Hz, supporting efficient energy handling in AC-biased environments.
• Ripple current performance — Low-frequency ripple current 65 mA (120 Hz) and high-frequency ripple current 104 mA (200 kHz), enabling use across a range of switching and line-frequency conditions.
• Leakage current — Specified leakage current 159.22 µA, allowing designers to budget leakage in power and hold-up applications.
• Endurance — Rated for 5000 hours at 105°C, providing sustained performance under elevated temperature and load.
• Operating temperature — Specified range −40°C to +105°C for reliable operation across common industrial and consumer environments.
• Package and mounting — Radial lead can, size φ10 × 20 mm, lead spacing 5.0 mm (±0.5 mm), available in bulk/no-terminal-forming or bag packing for flexible assembly.
• Regulatory — RoHS compliant.

Typical Applications

• Switching power supplies — Low-impedance construction and specified ripple-current ratings make this capacitor suitable for smoothing and decoupling in switching regulator outputs and input filters.
• Power conversion modules — 315 V rating supports use in higher-voltage DC link and intermediate bus circuits in general-purpose power conversion.
• Industrial and consumer electronics — General-purpose filtering, energy buffering, and DC decoupling where compact size and elevated-temperature endurance are required.

Unique Advantages

• Elevated voltage capability: 315 V rating enables deployment on higher-voltage rails without series stacking, simplifying board design.
• Defined ripple handling: Published ripple-current figures at both 120 Hz and 200 kHz allow designers to size parts for both low- and high-frequency conditions.
• Long endurance at high temperature: 5000 hours at 105°C supports longevity in thermally demanding applications and reduces maintenance frequency.
• Compact radial package: φ10 × 20 mm can with 5 mm lead spacing offers a small footprint for space-constrained PCBs while maintaining accessible leaded mounting.
• Predictable loss and leakage: Specified tanδ and leakage current values simplify thermal and power-loss budgeting during design validation.
• RoHS compliant: Conforms to lead-free requirements for environmentally constrained productions.
