UPM1H271MPD

The UPM1H271MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series, offering 270 µF capacitance at a 50 V rating. It is designed as a low-impedance, high-reliability power component with a compact can-style package (φ10 × 30.5 mm) and 5 mm lead spacing.

Engineered for demanding thermal and ripple environments, this capacitor targets automotive and power-electronics applications that require long endurance and stable performance across a wide temperature range.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance with a 50 V rated voltage and capacitance tolerance of ±20% (−20% ~ 20%).
• Low Impedance — Specified impedance of 65 mΩ to support low-loss filtering and decoupling at power rails.
• Ripple Current Handling — Low-frequency ripple current of 513 mA (120 Hz) and high-frequency ripple current of 900 mA (200 kHz) for effective smoothing across frequency ranges.
• Loss Characteristics — tanδ (DF) = 0.1 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics in design.
• High Endurance — Rated for 5000 hours of load life at 105°C, providing long-term stability under elevated-temperature stress.
• Wide Operating Temperature — Specified operating range from −55°C to +105°C to cover harsh-environment use cases.
• Mechanical & Mounting — Radial lead (polar) can package, size φ10 × 30.5 mm (L: 3.05 × D: 1.00 cm) with 5.0 mm lead spacing (±0.5 mm tolerance).
• Qualification & Compliance — AEC-Q200 rating and RoHS compliant as specified in the product data.
• Leakage Current — Specified leakage current of 405 µA for predictable standby loss behavior.
• Packaging Options — Available in Bulk (no terminal forming) or Bag packing for production handling flexibility.

Typical Applications

• Automotive Electronic Modules — Provides bulk capacitance and ripple smoothing for automotive control modules, supported by AEC-Q200 qualification and a −55°C to +105°C operating range.
• Power Supply Filtering — Low impedance (65 mΩ) and specified ripple currents make it suitable for primary/secondary smoothing and decoupling on power rails.
• DC–DC Converter Output — High endurance at 105°C and robust ripple-current ratings support stable output filtering in converter designs.

Unique Advantages

• Long Thermal Endurance: 5000 hours at 105°C delivers predictable lifetime for designs exposed to sustained high temperatures.
• Frequency-Span Ripple Performance: Separate low- and high-frequency ripple current specifications (513 mA @120 Hz, 900 mA @200 kHz) enable designers to validate behavior across operating spectra.
• Compact, Serviceable Form Factor: φ10 × 30.5 mm radial can with 5 mm lead spacing offers compactness while remaining easy to install in through-hole assemblies.
• Automotive-Grade Qualification: AEC-Q200 listing supports use in automotive electronics where component qualification is required.
• Predictable Electrical Loss: tanδ = 0.1 (20°C, 120 Hz) and specified leakage current provide clear parameters for thermal and energy-loss budgeting.
• Regulatory Compliance: RoHS compliance simplifies material compliance for regulated programs and supply chains.
