UPJ1E122MHD6

The UPJ1E122MHD6 is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series, designed for low-impedance power applications. It delivers 1.2 mF capacitance at a 25 V rating in a compact φ18 × 15 mm can and is intended for general-purpose use, with particular suitability for switching power supplies.

Engineered for reliability under load, this part offers extended endurance and defined ripple-current capability across low- and high-frequency conditions, making it appropriate for designers focused on stable power rails and long field life in electronic systems.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 μF) rated at 25 V with ±20% tolerance, providing bulk energy storage for power rail smoothing and decoupling.
• Low Impedance Design: UPJ series characteristic of low impedance suited to switching power supply environments, enabling improved ripple handling and transient response.
• Ripple Current Capability: Low-frequency ripple current 1.148 A (120 Hz) and high-frequency ripple current 1.4 A (200 kHz), supporting a range of switching and high-frequency power conditions.
• Reliability & Life: Rated for 5000 hours endurance at 105°C (load life), providing long-term stability in elevated-temperature applications.
• Temperature Range: Operates from −55°C to +105°C, accommodating a wide range of environmental conditions.
• Leakage & Loss Angle: Specified leakage current of 900 μA and tan δ of 0.14 (measured at 20°C, 120 Hz), enabling predictable performance characterization.
• Physical & Mounting: Radial lead, can-style package with dimensions φ18 × 15 mm and 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly handling.
• Compliance: RoHS compliant.

Typical Applications

• Switching Power Supplies: Low-impedance construction and specified ripple-current ratings make it well suited for smoothing and bulk energy storage in switching regulators.
• General-Purpose Power Filtering: Applicable where stable capacitance and defined leakage are required for board-level power stability across a wide temperature range.
• Industrial and Electronic Equipment: Designed for systems requiring long endurance at elevated temperatures and consistent performance over time.

Unique Advantages

• Extended Load-Life Endurance: 5000 hours at 105°C supports longer maintenance intervals and predictable lifespan in high-temperature power applications.
• Frequency-Range Ripple Support: Specified ripple currents at both 120 Hz and 200 kHz address demands from mains-frequency filtering to high-frequency switching environments.
• Compact, Serviceable Package: φ18 × 15 mm radial can with standard 7.5 mm lead spacing fits common through-hole layouts while simplifying replacement and prototyping.
• Predictable Electrical Characteristics: Defined tan δ and leakage current values enable reliable simulation and verification during design validation.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted-substance requirements.
• Production Availability: Mass-production status supports reasonable procurement and BOM planning.
