UVK1C223MRD

The UVK1C223MRD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s UVK series, providing 22,000 µF capacitance at a 16 V rating. Designed for general-purpose electronic power applications, it delivers high bulk capacitance and defined ripple handling in a compact can-style package.

Key attributes include a wide operating temperature range of -40°C to 85°C, endurance rated to 2000 hours at 85°C, and packaging options for bulk or bag handling. Note: this part is currently marked End Of Life.

Key Features

• High Capacitance (22,000 µF) — Provides substantial bulk energy storage for smoothing and decoupling in low-voltage power systems.
• Rated Voltage: 16 V — Suitable for 16 V rail applications where large capacitance is required.
• Radial Lead Package — Standard radial-lead can (φ22 × 40 mm) with 10 mm lead spacing and 0.5 mm lead-spacing tolerance for through-hole mounting.
• Ripple Current Capability — Low-frequency ripple current of 3.8 A (120 Hz) and high-frequency ripple current of 4.37 A (10 kHz) to support smoothing under varying ripple conditions.
• Loss Characteristics — Specified tangent of loss angle (tanδ) of 0.62, measured at 20°C, 120 Hz, for design consideration of ESR-related losses.
• Leakage Current — Leakage current specified at 10,560 µA, provided for accurate bias and hold-up time calculations.
• Endurance and Temperature Range — Rated for 2000 hours at 85°C; operating temperature −40°C to +85°C for use across typical commercial temperature profiles.
• RoHS Compliant — Conforms to RoHS environmental requirements.
• Packaging Options — Available as Bulk (no terminal forming) or Bag packing to suit assembly handling preferences.

Typical Applications

• Power Supply Bulk Filtering — Large 22,000 µF capacitance and high ripple capability make it suitable for bulk smoothing on low-voltage power rails.
• Hold-Up / Energy Storage — High capacitance supports short-term energy storage for maintaining voltages during transient drops.
• DC Rail Decoupling — Helps stabilize supply rails in systems where compact, high-capacitance through-hole components are needed.
• Audio Power Supplies — Provides bulk filtering and reservoir capacitance for audio amplifiers and power stages operating at or below 16 V.

Unique Advantages

• High Bulk Capacitance in a Compact Can: 22,000 µF in a φ22 × 40 mm body reduces board space compared with multiple smaller capacitors.
• Defined Ripple Performance: Specified ripple currents at both 120 Hz and 10 kHz let designers account for low- and high-frequency ripple conditions.
• Long Endurance Rating: 2000 hours at 85°C provides a predictable life metric for thermal-stressed designs.
• Clear Electrical Parameters: Published tanδ and leakage current values enable accurate IR, hold-up time, and loss budgeting.
• Through-Hole Mounting Simplicity: Radial lead form and standard 10 mm lead spacing simplify manual or wave-through-hole assembly processes.
