UVZ1E223MRD

The UVZ1E223MRD is a radial-lead aluminum electrolytic capacitor offering 22,000 µF of capacitance at a 25 V rating in a φ25 × 50 mm can. It is designed for general-purpose use where large bulk capacitance and through-hole mounting are required.

Key attributes include high ripple current capability at both low and high frequencies, a wide operating temperature range from −55 °C to 105 °C, and rated endurance of 2,000 hours at 105 °C. The part is supplied bulk or in bag packing and is RoHS compliant.

Key Features

• High Capacitance & Voltage: 22,000 µF capacitance at a 25 V rating for bulk energy storage and smoothing in power circuits.
• Ripple Current Performance: Low-frequency ripple current 3.25 A (120 Hz) and high-frequency ripple current 3.7375 A (10 kHz) to support AC ripple handling across frequency ranges.
• Wide Temperature Range & Endurance: Operates from −55 °C to 105 °C with an endurance rating of 2,000 hours at 105 °C.
• Electrical Loss & Leakage: Dissipation factor (tan δ) of 0.58 measured at 20 °C, 120 Hz, and a specified leakage current of 16,500 µA.
• Through-Hole Radial Package: Radial lead mounting in a φ25 × 50 mm can with 12.5 mm lead spacing for secure PCB placement and mechanical stability.
• Tolerance & Polarity: Capacitance tolerance −20% to +20% and polarized design for standard electrolytic applications.
• Regulatory Compliance: RoHS compliant for restricted substance requirements.

Typical Applications

• Power supply smoothing: Bulk capacitance for smoothing DC bus voltages and reducing output ripple in general-purpose power supplies.
• Bulk energy storage: Hold-up and decoupling where large capacitance is needed to support transient loads and energy buffering.
• Power converter filtering: Input and output filtering for switching regulators and converters requiring high ripple current capability.

Unique Advantages

• Large bulk capacitance: 22,000 µF provides substantial energy storage in a compact φ25 × 50 mm can, reducing the number of parallel components required.
• Dual-frequency ripple handling: Specified ripple currents at both 120 Hz and 10 kHz support performance across low- and high-frequency power stages.
• Wide operating temperature span: −55 °C to 105 °C supports deployment in environments with broad temperature variation.
• Long endurance at elevated temperature: Rated for 2,000 hours at 105 °C for sustained operation in higher-temperature applications.
• Secure through-hole mounting: Radial leads with 12.5 mm spacing enable robust mechanical and electrical connections for boards subject to vibration or handling.
• Standards conformity: RoHS compliance helps meet regulatory requirements for restricted substances.
