UCYW6330MHD3

The UCYW6330MHD3 is a radial‑lead, miniature aluminum electrolytic capacitor from Nichicon’s UCY series designed for high‑reliability power applications. It delivers 33 µF capacitance at a 420 V rating with a compact φ16 × 20 mm can and 7.5 mm lead spacing.

Targeted for demanding environments, this component combines high ripple current capability and long load life at elevated temperature, making it suitable for power supply and ballast use as well as automotive electronic systems (AEC‑Q200 qualified).

Key Features

• Electrical performance — Rated capacitance 33 µF with tolerance ±20% (measured at 120 Hz, 20°C) and a rated voltage of 420 V.
• High ripple current — Low‑frequency ripple current of 385 mA at 120 Hz and high‑frequency ripple current of 770 mA at 100 kHz, supporting demanding power filtering duties.
• Low loss (tan δ) — Tangent of loss angle (tan δ) specified at 0.24 (120 Hz, 20°C), enabling predictable dissipation characteristics.
• Long endurance at elevated temperature — Load life rated for 10,000 hours at +105°C, supporting sustained operation under thermal stress.
• Robust leakage specification — Specified leakage current 654.4 µA, consistent with long‑term stability requirements.
• Compact radial package — φ16 mm diameter × 20 mm length can with 7.5 mm lead spacing (±0.5 mm) for through‑hole designs; available in bulk or bag packing.
• Automotive suitability and compliance — AEC‑Q200 qualified and RoHS compliant, aligning with automotive electronics requirements and regulatory directives.

Typical Applications

• Power supplies — Smoothing and decoupling in high‑voltage DC power supplies where high ripple capability and long life at 105°C are required.
• Ballast circuits — Energy storage and ripple handling in ballast and lighting power circuits, as noted in the UCY series guidance.
• Automotive electronic systems — High‑voltage filtering and bulk capacitance in automotive modules that require AEC‑Q200 qualified components.

Unique Advantages

• High voltage capability: 420 V rating provides headroom for high‑voltage power applications without increasing package size.
• High ripple handling: Specified ripple currents at low and high frequencies (385 mA @120 Hz, 770 mA @100 kHz) reduce stress on surrounding circuitry and improve reliability.
• Extended high‑temperature life: 10,000‑hour endurance at +105°C supports long service intervals in thermal‑stress environments.
• Compact, manufacturable form factor: φ16×20 mm radial can with 7.5 mm lead spacing fits common through‑hole layouts while simplifying assembly and replacement.
• Automotive readiness and compliance: AEC‑Q200 qualification and RoHS compliance align the part with regulated and automotive design flows.
