UPA1A472MHD

The UPA1A472MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can designed for demanding power applications. As part of Nichicon's UPA series, it offers low impedance and high ripple-current capability in a compact φ12.5×30.5 mm package for switching power supplies and general-purpose power filtering.

Key performance attributes include 4.7 mF capacitance at 10 V, rated operation from −55 °C to 105 °C, and a 5000‑hour endurance rating at 105 °C, delivering stable performance in elevated-temperature power environments.

Key Features

• Capacitance & Voltage: 4700 µF (4.7 mF) nominal capacitance with a 10 V rated voltage and ±20% tolerance for bulk energy storage and smoothing.
• Low Impedance: Typical impedance of 36 mOhm, enabling reduced voltage ripple and improved power delivery in switching supplies.
• High Ripple Current Capability: Low-frequency ripple current of 2.312 A (120 Hz) and high-frequency ripple current of 2.72 A (10 kHz) to handle both mains-frequency and high-frequency switching ripple.
• Endurance at Elevated Temperature: 5000 hours life at 105 °C under rated DC bias plus rated ripple current, providing long-term reliability in hot operational environments.
• Leakage Current: Specified leakage current of 1410 µA, allowing designers to budget for standby and leakage budgets in power designs.
• Wide Operating Temperature: −55 °C to 105 °C rated temperature range for deployment across a broad set of industrial and electronic environments.
• Radial Lead, Through‑Hole Package: φ12.5×30.5 mm can with 5.0 mm lead spacing (±0.5 mm) for robust through‑hole mounting and ease of prototyping or assembly.
• Regulatory Compliance: RoHS compliant as specified for the UPA series.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where low impedance and high ripple handling reduce output ripple and improve regulator stability.
• Power Modules and DC–DC Converters: Energy storage and decoupling for converters and power rails that require compact, high‑ripple capacitors.
• Industrial and Instrumentation Electronics: Bulk filtering and noise suppression in control equipment that must operate across −55 °C to 105 °C.

Unique Advantages

• Compact, High‑Energy Storage: 4700 µF in a φ12.5×30.5 mm can provides substantial bulk capacitance in a small footprint to save board space.
• Reduced Ripple Impact: Low impedance (36 mOhm) combined with high ripple current ratings minimizes voltage ripple for cleaner power rails.
• Long High‑Temperature Life: 5000 hours endurance at 105 °C supports reliable operation in thermal stress conditions and extends maintenance intervals.
• Through‑Hole Robustness: Radial lead construction and standard 5 mm lead spacing simplify mechanical mounting and replacement in serviceable designs.
• Design Predictability: Clear electrical parameters (impedance, leakage, ripple currents, temperature range) allow precise sizing for power and hold‑up requirements.
• RoHS Compliant: Meets RoHS requirements for environmentally conscious product designs.
