UCY2V121MHD6

The UCY2V121MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series, configured in a radial-lead can. It provides 120 µF capacitance at a 350 V rated voltage with polarized construction and is offered in a compact φ18 × 30.5 mm can (L: 3.05 × D: 1.8 cm) with 7.5 mm lead spacing.

Designed for demanding power applications, this part delivers long life (12,000 hours at 105°C), high ripple-current capability, and AEC‑Q200 qualification—making it suitable for industrial and automotive power circuitry where durability and sustained performance are required. Packaging options include bulk (no terminal forming) and bag packing; the part is in mass production and RoHS compliant.

Key Features

• Rated Capacitance & Tolerance — 120 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable bulk energy storage for power rails.
• High Voltage Rating — 350 V rated voltage for use on higher-voltage DC rails and ballast/power-supply applications.
• Long Endurance — 12,000 hours load life at 105°C (DC bias plus rated ripple current), specified for sustained high-temperature operation.
• High Ripple-Current Capability — Low-frequency ripple current of 940 mA at 120 Hz and high-frequency ripple current of 1.88 A at 100 kHz to support switching and high-frequency power stages.
• Electrical Loss and Leakage — tan δ of 0.24 (max.) at 120 Hz, 20°C and a measured leakage current of 1,780 µA for predictable dissipation and current behavior.
• Temperature Range — Rated for −40°C to +105°C to cover a wide operating envelope in harsh environments.
• Compact Radial Package — φ18 mm diameter, 30.5 mm length can with 7.5 mm lead spacing and 0.5 mm lead-spacing tolerance, suitable for through-hole assembly.
• Automotive-Grade Qualification — AEC‑Q200 qualified, aligning the component with automotive and similarly demanding applications.
• Compliance — RoHS compliant per the UCY series specification.

Typical Applications

• Power Supplies — Bulk energy storage and ripple filtering on high-voltage DC rails in industrial and commercial power-supply designs.
• Ballasts and Lighting Electronics — Energy smoothing and ripple handling in ballast circuits where high-voltage, long-life components are required.
• Automotive Power Electronics — Voltage smoothing and decoupling in automotive electrical systems, benefiting from AEC‑Q200 qualification and high-temperature endurance.
• Industrial Converters and Inverters — Support for switching frequencies with specified high-frequency ripple-current capability and long life at elevated temperatures.

Unique Advantages

• Extended Lifetime at Elevated Temperature: 12,000-hour endurance at 105°C provides predictable lifespan in high-heat installations.
• High Ripple-Current Handling: Specified ripple currents at both low (940 mA at 120 Hz) and high (1.88 A at 100 kHz) frequencies enable use with a range of switching topologies.
• AEC‑Q200 Qualification: Offers a qualification level that supports use in automotive and similarly rigorous applications requiring validated component reliability.
• Compact Through-Hole Form Factor: Radial lead can (φ18 × 30.5 mm) with 7.5 mm lead spacing simplifies PCB layout for through-hole assemblies while saving board area compared with larger cans.
• Measured Dissipation and Leakage Data: tan δ (0.24) and a defined leakage current (1,780 µA) allow designers to account for losses and standby currents in system-level power budgets.
• Regulatory Compliance: RoHS compliance supports deployment in markets with environmental substance restrictions.
