UCS2C221MHD

The UCS2C221MHD is a radial-lead aluminum electrolytic capacitor designed for high ripple current and long-life applications. It delivers 220 µF at 160 V in a compact φ16×25 mm can with a 7.5 mm lead spacing, optimized for power-supply and ballast use.

Engineered for sustained operation at elevated temperatures, this capacitor is specified for 10,000 hours at 105°C and combines measurable ripple-handling capability with RoHS compliance for general-purpose industrial electronics.

Key Features

• Electrical performance — 220 µF nominal capacitance with tolerance of −20% to +20%, rated at 160 V DC and a tanδ (loss tangent) of 0.20 (measured at 20°C, 120 Hz).
• High ripple capability — Specified ripple current of 1.185 A at 120 Hz (low frequency) and 2.37 A at 100 kHz (high frequency), supporting smoothing and decoupling in power circuits.
• Long endurance — Load-life endurance rated for 10,000 hours at 105°C under DC bias plus rated ripple current.
• Leakage current — Measured leakage current of 1508 µA (after 1 minute at 20°C under rated voltage for this part).
• Mechanical package — Radial can package, dimensions φ16 × 25 mm, lead spacing 7.5 mm with 0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• Operating range & compliance — Rated for −40°C to +105°C operating temperature and RoHS compliant.
• Polarized type — Designed as a polarized electrolytic capacitor for DC applications.

Typical Applications

• Power Supplies — Bulk smoothing and output filtering where 160 V DC rating and high ripple current capability are required.
• Lighting Ballasts — Suitable for ballast circuits that need stable capacitance and long life at elevated temperatures.
• General-purpose Industrial Electronics — DC link, energy storage, and decoupling in industrial control and power modules.

Unique Advantages

• High ripple handling: Rated ripple currents at both low (1.185 A at 120 Hz) and high (2.37 A at 100 kHz) frequencies support reliable filtering under dynamic loads.
• Extended high-temperature life: 10,000-hour endurance at 105°C provides predictable performance and maintenance intervals for demanding installations.
• Compact radial form factor: φ16×25 mm can with 7.5 mm lead spacing provides a space-efficient solution for through-hole boards while keeping robust electrical performance.
• Clear electrical specifications: Defined tanδ, leakage current, and capacitance tolerance allow engineers to select and verify performance precisely against design requirements.
• Regulatory compliance: RoHS compliant to support environmentally constrained designs.
