UCS2E221MHD

The UCS2E221MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UCS series. Configured as a radial‑lead, polarized can, it provides 220 µF capacitance at a 250 V rating in a compact φ18 × 30.5 mm case.

Designed for general-purpose power applications—including power supplies and ballast circuits—this capacitor combines high ripple current capability and long endurance for demanding industrial and electronic designs operating across −40 °C to 105 °C.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 250 V working voltage and ±20% tolerance at 120 Hz, 20 °C.
• High Ripple Current — Low‑frequency ripple current of 1.565 A (120 Hz) and high‑frequency ripple current of 3.13 A (100 kHz), supporting heavy AC loading in power circuits.
• Long Life Endurance — Rated for 10,000 hours at 105 °C under specified D.C. bias plus rated ripple current, enabling extended service life in continuous‑use applications.
• Wide Temperature Range — Specified operating range from −40 °C to 105 °C for reliable performance across harsh environments.
• Leakage and Loss Characteristics — Specified leakage current of 2300 µA (after 1 minute at 20 °C) and tan δ (DF) of 0.20 at 20 °C, 120 Hz for predictable electrical behavior.
• Radial Lead Package — φ18 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm) for through‑hole mounting and straightforward assembly; available in Bulk (No Terminal Forming) or Bag packing.
• RoHS Compliant — Conforms to RoHS directive requirements for lead‑free environmental compliance.

Typical Applications

• Power Supplies — Bulk filtering and smoothing where high ripple tolerance and long life at elevated temperature are required.
• Ballast Circuits — Energy handling and ripple accommodation in lighting and ballast systems as noted for the UCS series.
• Industrial Electronics — Filtering and decoupling in motor controls, inverters, and other industrial power electronics operating up to 105 °C.
• General‑Purpose Electronics — Robust polarized capacitance for a range of general‑purpose applications that need reliable DC filtering and energy storage.

Unique Advantages

• High Ripple Handling: Supports 1.565 A at 120 Hz and 3.13 A at 100 kHz, allowing designers to manage substantial AC stress without frequent replacements.
• Extended Thermal Endurance: 10,000‑hour life rating at 105 °C provides predictable aging and maintenance planning for continuous‑duty systems.
• Compact Through‑Hole Form Factor: φ18 × 30.5 mm radial can with 7.5 mm lead spacing enables space‑efficient PCB layouts while preserving through‑hole robustness.
• Controlled Electrical Losses: Low tan δ (0.20 at 120 Hz) ensures consistent dissipation characteristics for stable performance in filter networks.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products requiring lead‑free components.
• Production Availability: Listed as mass production with standard bulk or bag packing for easier procurement and inventory planning.
