UCY2V221MHD

The UCY2V221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series, offering 220 µF capacitance at a 350 V rating in a compact φ18 × 46 mm can. It is designed for high-ripple, long-life power applications and is suited for power-supply and ballast use.

Key value propositions include high ripple-current capability across low and high frequencies, extended endurance of 12000 hours at 105°C, and qualification for AEC-Q200 to address demanding environments.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 350 V rated voltage and tolerance of -20% to +20%.
• High ripple-current capability — Rated ripple current of 1.3 A at 120 Hz and 2.6 A at 100 kHz to support power filtering under different switching frequencies.
• Long endurance — Load-life rated for 12000 hours at 105°C (endurance test conditions per datasheet) for extended operational reliability.
• Thermal range and stability — Operates from -40°C to +105°C with specified impedance and dissipation characteristics; dissipation factor tanδ specified at 0.24 (20°C, 120 Hz).
• Radial package — Through-hole radial can package (φ18 × 46 mm) with 7.5 mm lead spacing (±0.5 mm), available in bulk/bag packing for assembly flexibility.
• AEC-Q200 qualified & RoHS compliant — Series qualification noted as AEC-Q200 and compliance with RoHS directives for regulated designs.
• Leakage current specification — Part-specific leakage current listed as 3180 µA.

Typical Applications

• Power supplies — Smoothing and filtering in high-voltage power-supply rails where high ripple capability and long life are required.
• Ballasts — Designed for ballast applications as noted in the UCY series description, providing durable ripple handling and thermal endurance.
• Automotive power systems — Suitable for automotive electrical systems where AEC-Q200 qualification and wide temperature range are required.
• High-frequency switching circuits — Supports high-frequency ripple demands (2.6 A at 100 kHz) in switching converters and related circuitry.

Unique Advantages

• High ripple-current handling: Rated at 1.3 A (120 Hz) and 2.6 A (100 kHz), enabling reliable filtering across line- and switch-frequency applications.
• Extended operational life: 12000 hours at 105°C provides predictable endurance for continuous high-temperature operation.
• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive and other demanding environments.
• Compact radial form factor: φ18 × 46 mm can with 7.5 mm lead spacing fits common through-hole layouts while delivering high-voltage capability.
• Clear performance specs: Specified tanδ (0.24 at 20°C, 120 Hz) and explicit leakage current value (3180 µA) simplify electrical design and verification.
• Regulatory compliance: RoHS-compliant construction addresses environmental requirements for regulated products.
