UHD1H220MDD

The UHD1H220MDD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHD series, specified for general-purpose power filtering and decoupling in electronic designs. It delivers 22 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can with 2.0 mm lead spacing, offering measurable low- and high-frequency ripple handling and defined endurance at elevated temperature.

Key attributes include low loss (tanδ = 0.1 at 20°C, 120 Hz), leakage current specified at 11 µA, and an operating temperature range of −40°C to 105°C. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a 50 V rated voltage and tolerance of −20% to +20% for predictable bulk energy storage.
• Low Loss Characteristics — Tangent of loss angle (tanδ) of 0.1 measured at 20°C, 120 Hz, supporting efficient AC performance in ripple environments.
• Ripple Current Performance — Rated low-frequency ripple current 130.9 mA at 120 Hz and high-frequency ripple current 238 mA at 100 kHz, enabling use across a range of switching and line-frequency conditions.
• Leakage Current — Specified leakage current of 11 µA (after 2 minutes at 20°C), useful for designs sensitive to standby losses.
• Temperature & Endurance — Operating range −40°C to 105°C with an endurance rating of 2000 hours at 105°C for defined lifetime planning.
• Form Factor & Mounting — Radial lead, polarized can package sized φ5 × 11 mm with 2.0 mm lead spacing (±0.5 mm), suitable for through-hole board layouts.
• Packaging & Compliance — Available in bulk (no terminal forming) / bag packing; RoHS compliant.

Typical Applications

• General-purpose power supplies — Bulk smoothing and ripple reduction on 50 V rails in general electronic equipment.
• Local decoupling — Board-level energy storage and decoupling for analog and mixed-signal circuits operating within the part’s voltage and temperature limits.
• Consumer and industrial electronics — Filtering and stabilization in small form-factor modules where a compact φ5 × 11 mm can is required.

Unique Advantages

• Compact radial can — φ5 × 11 mm size provides capacitance and rated voltage in a small through-hole footprint for tight PCB layouts.
• Defined high-frequency performance — Specified ripple currents at both 120 Hz and 100 kHz give clear guidance for use with switching regulators and line-frequency filtering.
• Low dissipation factor — tanδ = 0.1 at 20°C, 120 Hz reduces AC loss in ripple conditions and aids thermal management.
• Clear lifetime specification — 2000 hours at 105°C supports reliable lifetime planning for designs operating near the upper temperature limit.
• RoHS compliant — Meets the stated environmental directive for restricted substances.
• Simple procurement options — Bulk and bag packing permit flexible handling for assembly and stocking.

Why Choose UHD1H220MDD?

UHD1H220MDD is positioned for engineers who need a compact, polarized aluminum electrolytic capacitor with explicit ripple-current and loss-factor specifications for general-purpose power filtering and decoupling. Its combination of 22 µF at 50 V, low tanδ, and defined leakage current makes it straightforward to evaluate in power-supply designs and board-level filtering applications.

This part is suitable for designs requiring a small through-hole capacitor with a known endurance at elevated temperature and RoHS compliance. Note that the part is listed as End Of Life, so consider lifecycle planning when specifying it into new designs.
