UPJ2A271MHD

The UPJ2A271MHD is a Nichicon UPJ series aluminum electrolytic capacitor offering 270 µF capacitance at a 100 V rated voltage in a radial-lead can. It is part of a low-impedance family designed for reliable performance under sustained load, optimized for power supply use.

With a wide operating temperature range from −55 °C to 105 °C and a 5000-hour endurance rating at 105 °C, this component targets general-purpose power filtering and smoothing on higher-voltage rails where long-term thermal endurance and elevated-voltage capability are required.

Key Features

• High Voltage Rating — 100 V rated voltage suitable for higher-voltage DC rails and power modules.
• Substantial Capacitance — 270 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C) for bulk energy storage and smoothing.
• Low Impedance Design — UPJ series specification targets low impedance for switching power supply applications.
• Long Endurance at Elevated Temperature — 5000 hours rated life at 105 °C for extended reliability under thermal stress.
• Ripple Current Capability — Low-frequency ripple current 480.51 mA (120 Hz) and high-frequency ripple current 843 mA (200 kHz) to handle dynamic load conditions.
• Measured Dissipation Factor (tan δ) — tan δ = 0.08 measured at 20 °C, 120 Hz, 100 V (DF measurement condition), supporting predictable AC performance.
• Compact Radial Package — φ12.5 × 40 mm can with 5.0 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Leakage Current — Specified leakage current of 810 µA at product conditions for predictable quiescent behavior.
• Regulatory Compliance — RoHS compliant.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; status: mass production.

Typical Applications

• Switching Power Supplies — Low-impedance UPJ construction and robust ripple current ratings make the UPJ2A271MHD suited for output filtering and energy storage in switching regulators.
• General-purpose Power Filtering — 270 µF at 100 V provides bulk capacitance for smoothing and decoupling on higher-voltage DC rails.
• High-Voltage DC Rail Support — 100 V rating and extended temperature endurance support power modules and equipment that require reliable filtering at elevated voltages and temperatures.

Unique Advantages

• Designed for High-Temperature Endurance: 5000 hours at 105 °C provides long-term stability in thermally demanding environments.
• Balanced AC Performance: Specified tan δ and measurable ripple current ratings deliver predictable behavior across low and high frequency conditions.
• High-Voltage Bulk Capacitance: 270 µF at 100 V supplies substantial stored energy in a compact radial can for higher-voltage designs.
• Through-Hole Mounting Simplicity: Radial lead package with defined 5.0 mm lead spacing and 0.5 mm tolerance eases prototype and production assembly for board-level power sections.
• Regulatory and Supply Assurance: RoHS compliance and mass-production availability facilitate design-in and volume sourcing.
