UCYW6121MHD6

The UCYW6121MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UCY series. It is a radial-lead, polarized device specified at 120 µF and 420 V, designed for applications that require sustained ripple handling and long operational life.

Targeted at power electronics and automotive applications, this capacitor delivers high ripple current capability and endurance up to 12,000 hours at 105°C, providing stability and durability for demanding power-supply and ballast uses.

Key Features

• Electrical Performance — 120 µF capacitance with ±20% tolerance and a rated voltage of 420 V; tangent of loss angle (tan δ) 0.24 measured at 20°C, 120 Hz.
• High Ripple Capability — Low-frequency ripple current 945 mA at 120 Hz and high-frequency ripple current 1.89 A at 100 kHz, enabling effective smoothing in power circuits.
• Leakage Current — Specified leakage current of 2116 µA under rated conditions.
• Long Endurance — Load-life rating of 12,000 hours at 105°C with D.C. bias plus rated ripple current to support extended field service.
• Thermal Range — Operating temperature from −40°C to +105°C for broad thermal environments.
• Mechanical & Package — Miniature can size φ18 × 46 mm (L: 4.6 × D: 1.8 cm) with 7.5 mm lead spacing and radial lead mounting; supplied bulk (no terminal forming) or bag packed.
• Standards & Compliance — AEC‑Q200 qualified and RoHS compliant; manufactured by Nichicon and currently in mass production.

Typical Applications

• Power Supplies — Smoothing and ripple filtering in industrial and embedded power-supply designs where high ripple handling is required.
• Ballasts and Lighting Power — Suited for ballast applications that demand sustained ripple current performance and long operating life.
• Automotive Power Electronics — Applicable to automotive power circuits and systems where AEC‑Q200 qualification and extended endurance at 105°C are required.

Unique Advantages

• High ripple-current tolerance: Dual-specified ripple currents (945 mA @120 Hz and 1.89 A @100 kHz) help reduce heating and improve voltage smoothing under AC and switching loads.
• Extended operational life: 12,000-hour endurance at 105°C provides predictable long-term performance in high-temperature installations.
• AEC‑Q200 qualification: Provides an industry-recognized reliability baseline for automotive and similarly demanding applications.
• Compact radial-lead form factor: φ18 × 46 mm can with 7.5 mm lead spacing gives a space-efficient solution for through-hole designs.
• Regulatory compliance: RoHS compliant construction supports environmental and regulatory requirements.
