UVK0J223MHD

The UVK0J223MHD is a miniature aluminum electrolytic capacitor in Nichicon’s UVK series, offered as a standard radial‑lead type. It delivers high bulk capacitance (22,000 µF) at a low rated voltage of 6.3 V in a compact φ18 × 35.5 mm can.

Designed for general purpose power applications, this part provides bulk energy storage and ripple current handling with a rated low‑frequency ripple current of 3.2 A (120 Hz) and high‑frequency ripple current of 3.68 A (10 kHz). It is RoHS‑compliant and optimized for designs requiring high capacitance in a small radial package.

Key Features

• High Capacitance: 22,000 µF nominal capacitance for bulk energy storage, smoothing, and decoupling in low‑voltage power rails.
• Rated Voltage: 6.3 V rated voltage suitable for low‑voltage power supply stages and energy reservoir applications.
• Ripple Current Handling: Low‑frequency ripple current 3.2 A at 120 Hz and high‑frequency ripple current 3.68 A at 10 kHz to support both mains‑frequency filtering and higher‑frequency switching environments.
• Temperature and Endurance: Operating range −40 °C to +85 °C with a rated endurance of 2000 hours at 85 °C, supporting sustained operation under elevated temperature conditions.
• Compact Radial Can: Miniature radial can package (φ18 × 35.5 mm / L: 3.55 × D: 1.8 cm) with 7.5 mm lead spacing, enabling dense PCB layouts.
• Electrical Characteristics: Polarized aluminum electrolytic construction with capacitance tolerance of −20% to +20% and a measured dielectric loss defined under 20 °C, 120 Hz conditions.
• Leakage Current: Specified leakage current of 4,158 µA after rated voltage application, useful for assessing standby and holding current in power designs.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to accommodate different assembly and handling preferences.
• Regulatory Compliance: RoHS‑compliant to meet common lead‑free environmental requirements.

Typical Applications

• Power supply bulk smoothing: High capacitance and rated ripple currents make this capacitor suitable for bulk smoothing on low‑voltage power rails and linear regulators.
• Switching regulator output filtering: Supports output decoupling in DC‑DC converters where both low‑frequency and high‑frequency ripple handling are required.
• Backup energy storage: Provides reservoir capacitance for short‑term hold‑up and energy buffering in embedded systems and power modules.
• General purpose electronics: Useful across consumer and industrial general purpose circuits that require compact, high‑value electrolytic capacitance.

Unique Advantages

• Large capacitance in a small footprint: 22,000 µF in a φ18 × 35.5 mm can enables compact board layouts without sacrificing bulk energy storage.
• Dual‑frequency ripple capability: Rated ripple currents specified at both 120 Hz and 10 kHz let designers evaluate performance across mains and switching frequencies.
• Wide operating temperature span: −40 °C to +85 °C supports deployment in a broad range of ambient conditions common to general purpose electronics.
• Long endurance rating: 2000 hours at 85 °C provides predictable life performance for designs needing sustained operation at elevated temperatures.
• Flexible packaging: Bulk or bag packing options simplify procurement and handling for prototyping or production volumes.
