UPJ2G4R7MHD

The UPJ2G4R7MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a polarized radial-lead can designed for general-purpose power applications, offering a compact footprint (φ12.5 × 20 mm) and 5 mm lead spacing.

Engineered for low impedance and sustained operation, the device provides a 4.7 µF capacitance at a 400 V rating with endurance up to 5000 hours at 105°C, making it suitable for switching power supplies and other power-conversion circuits that require stable filtering and ripple handling.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal with a tolerance of -20% to +20% for predictable filtering behavior.
• Rated Voltage — 400 V rating to support higher-voltage DC bus and power applications.
• Low Dissipation Factor — tanδ = 0.25 (measured at 20°C, 120 Hz, 400 V) to help minimize dielectric losses in AC/ripple conditions.
• Ripple Current Capability — 55 mA at 120 Hz (low frequency) and 88 mA at 200 kHz (high frequency) for effective smoothing of both line-frequency and high-frequency switching ripple.
• Leakage Current — Specified leakage current of 175.2 µA for predictable leakage behavior after voltage application.
• Endurance & Temperature Rating — Rated for 5000 hours at 105°C and an operating temperature range of -40°C to +105°C, supporting reliable operation in elevated-temperature environments.
• Package & Mounting — Radial lead, can-style package with overall size φ12.5 × 20 mm and 5 mm lead spacing (±0.5 mm); available in bulk or bag packing (no terminal forming).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and endurance at 105°C make this capacitor suitable for output filtering and smoothing in switching regulators and converters.
• General Purpose Power Filtering — 4.7 µF at 400 V provides DC-link and rail decoupling in medium-voltage power circuits.
• Industrial Power Conversion — High-temperature endurance and specified ripple current handling support reliable performance in industrial power electronics and control equipment.

Unique Advantages

• High-voltage capability: A 400 V rating enables usage on higher DC buses without changing capacitor topology.
• Long-term thermal endurance: Rated for 5000 hours at 105°C to provide predictable life in elevated-temperature applications.
• Compact radial form factor: φ12.5 × 20 mm can and 5 mm lead spacing save board area while keeping through-hole mounting simplicity.
• Measurable ripple performance: Specified ripple currents for both low- and high-frequency domains (55 mA @120 Hz, 88 mA @200 kHz) help designers size decoupling networks accurately.
• Controlled dissipation and leakage: Defined tanδ and leakage current figures support thermal and loss budgeting in power designs.
• Regulatory compliance: RoHS compliance supports integration into products targeting restricted-substance requirements.
