UCS2D221MHD

The UCS2D221MHD is a miniature radial aluminum electrolytic capacitor from Nichicon’s UCS series. It provides 220 µF capacitance at a 200 V rating in a compact can-style radial lead package designed for general-purpose power electronics.

Engineered for high ripple-current environments and extended operation at elevated temperature, this capacitor is suited for power supply and ballast applications and is RoHS compliant.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 200 V and capacitance tolerance of ±20% (−20% to +20%).
• High Ripple Current — Rated ripple current of 1.183 A at 120 Hz and 2.365 A at 100 kHz, supporting applications with significant AC ripple content.
• Long Elevated-Temperature Lifetime — Endurance specified for 10000 hours at +105°C (8000 hours for certain sizes in the series), enabling extended field life in hot operating environments.
• Compact Radial Package — Radial can (through-hole) construction with lead spacing 7.5 mm and physical size L: 2.5 × D: 1.8 cm for space-constrained PCB layouts.
• Wide Operating Temperature — Guaranteed performance from −40°C to +105°C for use across a broad range of ambient conditions.
• Series Leakage and Loss Specifications — Series specification for leakage current: I ≤ 0.04CV + 100 µA after 1 minute at 20°C; tangent of loss angle (tan δ) for 200 V parts up to 0.20 (measured at 120 Hz, 20°C).
• Polarized, General-Purpose Use — Polarized aluminum electrolytic intended for general-purpose power-electronics roles such as smoothing and energy storage in DC circuits.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk filtering and ripple handling in DC power-supply stages where high ripple-current capability and elevated-temperature endurance are required.
• Ballasts — AC/DC conversion and smoothing in ballast circuits, benefiting from the part’s high ripple-current rating and long life at +105°C.
• General-Purpose Power Electronics — Through-hole radial mounting for assemblies that require reliable electrolytic capacitance in a compact footprint.
• High-Ripple Environments — Circuits exposed to significant AC ripple where the specified ripple current at both low and high frequencies is a design consideration.

Unique Advantages

• High ripple-current capability: Specifies 1.183 A (120 Hz) and 2.365 A (100 kHz), allowing designers to size capacitors accurately for ripple-heavy applications.
• Extended elevated-temperature life: Rated for 10000 hours at +105°C (series endurance), supporting long-term reliability in hot enclosures.
• Compact radial form factor: Small can dimensions (L: 2.5 × D: 1.8 cm) and 7.5 mm lead spacing minimize PCB area while retaining through-hole robustness.
• Wide operating temperature range: −40°C to +105°C rating provides predictable performance across diverse ambient conditions.
• Quantifiable electrical loss and leakage: Series tan δ and leakage-current limits (I ≤ 0.04CV + 100 µA) give measurable parameters for circuit analysis and reliability projections.
• Regulatory compliance: RoHS conformity simplifies regulatory tracking for end products.
