UCS2E470MHD

The UCS2E470MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UCS series. It is a radial-lead, polarized capacitor rated at 250 V with 47 µF capacitance, designed for general-purpose power conditioning in equipment that requires compact high-voltage smoothing and filtering.

Key value comes from its high ripple-current capability and long endurance: the part supports both low- and high-frequency ripple loads and is specified for 10,000 hours at 105°C, making it suitable for demanding power-supply and ballast applications.

Key Features

• Capacitance & Voltage: 47 µF capacitance at a 250 V rated voltage for higher-voltage rail applications.
• High Ripple Current: Rated for 490 mA at 120 Hz and 980 mA at 100 kHz, enabling robust handling of both low- and high-frequency ripple currents.
• Long Endurance: Load-life specification of 10,000 hours at 105°C, providing sustained performance in elevated-temperature environments.
• Temperature Range: Operates from −40°C to 105°C to support a wide range of thermal conditions.
• Low Loss (tan δ): tan δ = 0.20 measured at 20°C, 120 Hz, indicating low dissipation for this voltage class.
• Leakage Current: Specified leakage current of 570 µA (after 1 minute at 20°C), suitable for power applications where predictable leakage is required.
• Compact Radial Package: φ12.5×20 mm can with 5.0 mm lead spacing (±0.5 mm), radial-lead format for through-hole assembly and straightforward PCB placement.
• RoHS Compliant & Packaging: Meets RoHS requirements; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Power Supplies: Filtering and smoothing on intermediate and high-voltage rails where 250 V rating and high ripple handling improve regulator stability.
• Ballasts: Energy storage and ripple mitigation in ballast circuits, leveraging the UCS series’ suitability for ballast application.
• General-Purpose Electronics: Use in a wide range of general-purpose designs requiring a compact, high-voltage electrolytic with long operational life.

Unique Advantages

• High ripple tolerance: Up to 980 mA at 100 kHz and 490 mA at 120 Hz, enabling reliable performance under repetitive AC load conditions.
• Extended operational life: 10,000 hours at 105°C reduces maintenance and replacement frequency in prolonged high-temperature deployments.
• Compact high-voltage form factor: 250 V capability in a φ12.5×20 mm radial can conserves board area while providing necessary voltage margin.
• Wide operating temperature window: −40°C to 105°C supports deployment across varied ambient conditions without derating outside specified limits.
• Predictable electrical behavior: tan δ = 0.20 and specified leakage current provide designers with measurable parameters for circuit simulations and reliability planning.
• RoHS compliance and flexible packing: Environmentally compliant and offered in bulk or bag packing to fit production and prototyping workflows.
