UCS2W330MHD6

The UCS2W330MHD6 is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon’s UCS series. It is a radial‑lead, polarized capacitor specified at 33 µF and 450 V, designed for demanding power applications that require extended lifetime and high ripple capability.

With a rated operating range of −40°C to 105°C, a 10,000‑hour endurance at 105°C, and high ripple current capability at both low and high frequencies, this part is targeted at power supplies, ballast circuits and other general‑purpose industrial power electronics where compact, durable bulk energy storage is required.

Key Features

• Capacitance and Tolerance — 33 µF with a tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• High Voltage Rating — Rated voltage: 450 V, suitable for high‑voltage power rail applications within that rating.
• High Ripple Current Capability — Low‑frequency ripple current 490 mA (120 Hz) and high‑frequency ripple current 980 mA (100 kHz), enabling reliable operation under AC ripple stress.
• Leakage Current — Specified leakage current of 694 µA (measured after application conditions as defined for the part), supporting predictable bias behavior in designs.
• Long Life at Elevated Temperature — Endurance rated for 10,000 hours at 105°C under specified conditions, delivering extended service life in thermally challenging environments.
• Loss Factor (tan δ) — tanδ = 0.24 measured at 20°C, 120 Hz for the 450 V rating, providing known dissipation characteristics for thermal and stability calculations.
• Compact Radial Package — Case size φ18 × 20 mm with 7.5 mm lead spacing (±0.5 mm); radial can style facilitates through‑hole mounting and robust mechanical retention.
• RoHS Compliant — Conforms to RoHS directive requirements.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and handling.

Typical Applications

• Power Supplies — Bulk energy storage and filtering on high‑voltage DC rails where 450 V rating and high ripple endurance are required.
• Ballast Circuits — Suited for lamp ballast and similar circuits identified in the UCS series documentation for high ripple and long life.
• Industrial Power Conversion — DC link and smoothing applications in compact power modules that must withstand elevated temperature and ripple stress.
• General‑Purpose High‑Voltage Electronics — Any general‑purpose application requiring a compact, polarized electrolytic capacitor rated to 450 V with a long rated life.

Unique Advantages

• High Voltage Handling: 450 V rating supports higher DC bus voltages without multiple component stacking, simplifying design.
• Designed for Continuous Ripple: Specified ripple currents at both 120 Hz and 100 kHz enable reliable performance across switching and line‑frequency environments.
• Extended Elevated‑Temperature Lifetime: 10,000 hours at 105°C provides predictable aging characteristics for long‑service designs.
• Compact Radial Can Format: φ18 × 20 mm size with 7.5 mm lead spacing offers a space‑efficient footprint for through‑hole assemblies.
• Controlled Leakage: Defined leakage current figure helps designers manage standby losses and bias behavior in power circuits.
• RoHS Compliance: Meets environmental regulatory requirements for lead‑free applications.
