UPJ2C4R7MPD

The UPJ2C4R7MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, designed for low-impedance power applications. It delivers 4.7 µF at 160 V in a compact φ10 × 12.5 mm can, targeting general-purpose power filtering and switching power supply use where reliability and small size are important.

Key Features

• Capacitance & Voltage — 4.7 µF nominal capacitance with a rated voltage of 160 V and a capacitance tolerance of ±20% (-20% to +20%).
• Low impedance performance — Specified tangent of loss angle (tanδ) of 0.2 measured at 20°C and 120 Hz, supporting low-loss operation in power circuits.
• High reliability endurance — Rated to withstand 5,000 hours at 105°C under applied DC bias plus ripple current, providing stable capacitance and controlled leakage over life.
• Ripple current capability — Low-frequency ripple current 57 mA (120 Hz) and high-frequency ripple current 91.2 mA (200 kHz), useful for smoothing and decoupling in switching supplies.
• Leakage current — Specified leakage current of 115.2 µA, supporting predictable bias behavior after voltage application.
• Compact radial package — φ10 × 12.5 mm can with 5.0 mm lead spacing (±0.5 mm) and radial leads for through-hole mounting and straightforward mechanical placement.
• Wide operating temperature — Rated for operation from −40°C to +105°C.
• RoHS compliant — Meets RoHS environmental requirements.

Typical Applications

• Switching Power Supplies — Low-impedance and high-reliability characteristics make the UPJ2C4R7MPD suitable for output smoothing and bulk decoupling in switch-mode supplies.
• Power Rail Decoupling — Compact radial package and defined ripple current ratings support local decoupling on 160 V rails and intermediate power stages.
• General-Purpose Power Circuits — For general-purpose smoothing, filtering, and energy storage in industrial and consumer power electronics where through-hole mounting is preferred.

Unique Advantages

• Compact footprint with high voltage — Provides 160 V rating in a φ10 × 12.5 mm can, enabling high-voltage designs without large board area.
• Engineered for switching environments — Low tanδ and specified ripple current ratings deliver predictable performance under both low- and high-frequency ripple conditions.
• Long thermal endurance — 5,000-hour life at 105°C helps reduce maintenance and replacement frequency in continuously powered systems.
• Predictable leak and loss characteristics — Specified leakage current and tanδ give designers measurable parameters for bias and thermal design margins.
• Through-hole robustness — Radial lead form factor simplifies mechanical retention and field replaceability compared with surface-mount alternatives.
