UVY1A221MDD

The UVY1A221MDD is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 10 V rating. It is designed for general-purpose, low-voltage board-level applications that require a compact, polarized electrolytic solution in a radial can package.

Key electrical characteristics include a capacitance tolerance of -20% to +20%, a measured dissipation factor (tanδ) of 0.24 at 20°C/120 Hz, low-frequency and high-frequency ripple current ratings, and a rated operating temperature range of -55°C to 105°C. Status: End Of Life.

Key Features

• Capacitance and Tolerance — 220 µF nominal with a tolerance of -20% to +20%, suitable for bulk capacitance roles in low-voltage circuits.
• Rated Voltage — 10 V DC rating for use in low-voltage power rails.
• Dissipation Factor (tanδ) — tanδ = 0.24 measured at 20°C and 120 Hz, providing a defined loss characteristic for design calculations.
• Ripple Current Ratings — Low-frequency ripple current 155 mA (120 Hz) and high-frequency ripple current 232.5 mA (10 kHz) to support both mains-frequency and higher-frequency ripple conditions.
• Leakage Current — Specified leakage current of 66 µA under rated conditions for predictable standby losses.
• Temperature and Endurance — Operating range -55°C to 105°C with a rated endurance of 1000 hours at 105°C.
• Compact Radial Package — Physical size φ5 × 11 L with dimensions L: 1.1 × D: 0.5 cm and 2.0 mm lead spacing (±0.5 mm) for through-hole assemblies and compact board layouts.
• Packaging Options — Available in Bulk (No Terminal Forming) or Bag Packing to suit prototyping and production handling.
• RoHS Compliance — Declared RoHS compliant for environmental conformity.

Typical Applications

• General-Purpose Low-Voltage Circuits — Suited to designs operating up to the part's 10 V rating where compact bulk capacitance is needed.
• Board-Level Power Filtering — Radial-lead package and defined ripple current ratings make this capacitor appropriate for through-hole power filtering and decoupling on small PCBs.
• Prototyping and Small Modules — Compact φ5 × 11 L size and bag/bulk packing options support prototyping and assembly of compact electronic modules.

Unique Advantages

• Predictable Loss Characteristics: Measured tanδ (0.24 at 20°C/120 Hz) provides a clear basis for thermal and impedance planning.
• Broad Operating Temperature: Rated from -55°C to 105°C, enabling use across a wide range of environmental conditions supported by the datasheet.
• Defined Ripple Capability: Separate low- and high-frequency ripple current specifications (155 mA at 120 Hz and 232.5 mA at 10 kHz) allow designers to evaluate performance under different ripple spectra.
• Compact Through-Hole Form Factor: Small φ5 × 11 L radial can and 2 mm lead spacing help minimize board footprint while using a through-hole mounting method.
• Long-Established Endurance Spec: 1000 hours at 105°C gives a quantifiable lifetime metric for thermal stress planning.
• Environmentally Declared: RoHS compliance supports regulatory needs in many regions.
