UPA1E271MPD

The UPA1E271MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPA series, supplied in a radial-lead can (φ8 × 11.5 mm). Designed for general-purpose and power-supply circuitry, it delivers low impedance and high ripple-current capability suitable for switching power supplies and power-management applications.

With a 270 µF capacitance at 25 V, a wide operating temperature range from −55°C to +105°C, and a rated endurance of 3000 hours at 105°C, the UPA1E271MPD balances compact size and robust performance for embedded and industrial designs.

Key Features

• Capacitance and Voltage: 270 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20%.
• Low Impedance: Measured impedance of 180 mΩ supports stable filtering and fast transient response in power circuits.
• High Ripple Current: Rated ripple current of 409.5 mA at 120 Hz and 630 mA at 10 kHz, enabling effective smoothing in switching supplies and converters.
• Loss Characteristics: Dissipation factor (tan δ) of 0.14 (measured at 20°C, 120 Hz) for predictable AC behavior.
• Leakage Current: Specified leakage current of 202.5 µA for low standby loss in DC circuits.
• Temperature and Endurance: Operating range −55°C to +105°C with a life rating of 3000 hours at 105°C under rated conditions.
• Compact Radial Package: φ8 × 11.5 mm can with 3.5 mm lead spacing (lead spacing tolerance ±0.5 mm); radial-lead mounting for through-hole assemblies.
• Packaging & Production Status: Available in bulk (no terminal forming) or bag packing; currently in mass production.
• RoHS Compliant: Meets RoHS requirements for environmental compliance.

Typical Applications

• Switching Power Supplies: Low-impedance, high-ripple performance makes it suitable for input/output filtering in switching regulators and SMPS modules.
• DC–DC Converters: Compact radial package and strong ripple-current rating support smoothing and decoupling in point-of-load converters.
• Power-Management Modules: Useful for bulk decoupling and energy buffering in power-management and distribution boards.
• Industrial and Consumer Electronics: General-purpose filtering where a small footprint and extended temperature range are required.

Unique Advantages

• Space-efficient power filtering: φ8 × 11.5 mm can size delivers 270 µF capacitance in a compact radial package for dense PCB layouts.
• High ripple handling: Dual ripple-current ratings (120 Hz and 10 kHz) enable reliable performance across common power-frequency and high-frequency switching environments.
• Thermal endurance: 3000 hours at 105°C provides predictable aging and long-term stability in thermally demanding applications.
• Predictable electrical behavior: Low impedance and a defined tan δ (0.14 at 20°C, 120 Hz) support accurate design margins for filtering and decoupling networks.
• Through-hole reliability: Radial-lead mounting with standard 3.5 mm lead spacing simplifies assembly and replacement in serviceable designs.
• Regulatory readiness: RoHS compliance supports deployment in regulated product lines and markets.
