UPA1C272MHD

The UPA1C272MHD is a miniature, high-reliability radial aluminum electrolytic capacitor in Nichicon’s UPA series. It provides 2.7 mF (2700 µF) capacitance at 16 V in a compact φ12.5×25 mm can with 5 mm lead spacing.

Designed for general-purpose power applications and switching power supplies, this polarized capacitor combines low impedance and high ripple-current capability with long endurance at elevated temperature (5000 hours at 105 °C), making it suitable for compact power modules and filtering tasks.

Key Features

• Capacitance & Voltage: 2.7 mF (2700 µF) rated at 16 V for bulk filtering and energy smoothing in low-voltage power rails.
• Low Impedance: Specified impedance of 44 mΩ supports efficient ripple suppression and stable performance under load.
• High Ripple Current: Low-frequency ripple current of 1.938 A (120 Hz) and high-frequency ripple current of 2.28 A (10 kHz) enable effective handling of switching currents in power supplies.
• Wide Temperature Range: Operates from −55 °C to +105 °C, with endurance tested to 5000 hours at 105 °C for reliable long-term operation.
• Compact Radial Package: φ12.5×25 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly options.
• Leakage & Dissipation: Leakage current specified at 1296 µA and tan δ (DF) of 0.18 measured at 20 °C, 120 Hz—data for evaluating standby losses and dissipation in designs.
• RoHS Compliant: Manufactured to meet RoHS requirements for restriction of hazardous substances.

Typical Applications

• Switching Power Supplies: Low impedance and high ripple-current capability make the UPA1C272MHD effective for output smoothing and bulk decoupling in compact switching regulators.
• Power Filtering in Compact Modules: Compact φ12.5×25 mm package and radial leads suit tight board layouts where reliable filtering is required.
• General-Purpose Power Rails: Use for bulk capacitance and smoothing on low-voltage rails where long endurance and stable performance at elevated temperature are needed.

Unique Advantages

• High Energy Density in a Small Footprint: 2700 µF in a φ12.5×25 mm case provides substantial capacitance where board space is limited.
• Engineered for Switching Environments: High-frequency ripple current rating (2.28 A at 10 kHz) and low impedance (44 mΩ) reduce voltage ripple and improve regulator stability.
• Long-Term Reliability at Elevated Temperature: 5000 hours endurance at 105 °C supports designs intended for sustained thermal stress.
• Easy Through-Hole Integration: Radial lead form with 5 mm spacing simplifies insertion into power assemblies and prototyping workflows.
• Regulatory Compliance: RoHS-compliant construction supports environmental and supply-chain requirements.
