UPJ2G220MHD

The UPJ2G220MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPJ series, specified at 22 µF and 400 V. It is a low-impedance, polarized can-style capacitor designed for general-purpose power filtering and smoothing in power electronics, including switching power supplies.

Key value propositions include low impedance characteristics, defined high-voltage capability (400 V), and thermal endurance with a rated life of 5000 hours at 105 °C, making it suitable for demanding power applications that require sustained performance under elevated temperature and ripple stress.

Key Features

• Rated Capacitance and Voltage — 22 µF capacitance rated at 400 V, providing high-voltage filtering in compact radial-can format.
• Low Impedance Design — UPJ series emphasis on low impedance for improved ripple handling in power supply applications.
• Ripple Current Capability — Handles 130 mA at 120 Hz (low frequency) and 208 mA at 200 kHz (high frequency) to support both line-frequency and switching ripple environments.
• Endurance — Rated for 5000 hours at 105 °C, enabling long-term operation under elevated temperature load conditions.
• Loss Characteristics — Tangent of loss angle (tanδ) specified at 0.25 (measured at 20 °C, 120 Hz, 400 V) for predictable AC performance.
• Leakage Current — Specified leakage current of 452 µA, useful for design margining in power circuits.
• Mechanical and Mounting — Radial lead, can package with φ16 × 30.5 mm body size, lead spacing 7.5 mm (±0.5 mm), and lead diameter per series dimensions.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly preparation.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and defined ripple current ratings make the part suitable for output filtering and decoupling in switch-mode power designs.
• Industrial Power Modules — 400 V rating and 5000-hour thermal endurance support use in industrial DC bus filtering and bulk energy storage.
• DC-DC Converters — Compact radial-can footprint and high-voltage capability suit board-level input/output filtering on converter modules.

Unique Advantages

• High-voltage capability: 400 V rating supports applications requiring elevated DC bus voltages without stacking components.
• Thermal reliability: 5000 hours endurance at 105 °C offers predictable life under continuous elevated-temperature operation.
• Measured ripple performance: Specified low- and high-frequency ripple current figures allow designers to size capacitance for both line and switching noise.
• Predictable AC loss: tanδ specified at measurement conditions (20 °C, 120 Hz, 400 V) helps in AC-loss and thermal-rise calculations.
• Compact radial package: φ16 × 30.5 mm can with 7.5 mm lead spacing simplifies through-hole mounting and retrofits in legacy layouts.
• RoHS compliance and packing flexibility: RoHS-compliant materials with bulk and bag packing options streamline procurement and assembly logistics.
