UVK1E153MRD

The UVK1E153MRD is a miniature aluminum electrolytic capacitor from Nichicon’s UVK series, configured as a radial-lead, standard-type device. It provides a high capacitance value of 15,000 µF at a rated voltage of 25 V for general-purpose DC smoothing and bulk energy storage in electronic power systems.

Key electrical characteristics include high ripple-current capability (3.8 A at 120 Hz, 4.37 A at 10 kHz), a rated operating range of −40 °C to 85 °C, and an endurance rating of 2,000 hours at 85 °C. Status: End Of Life.

Key Features

• High Capacitance & Voltage: 15,000 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20% for bulk energy storage and filtering on 25 V rails.
• Ripple Current Performance: Low-frequency ripple current of 3.8 A at 120 Hz and high-frequency ripple current of 4.37 A at 10 kHz to support heavy AC ripple and switching supply applications.
• Endurance & Stability: Rated for 2,000 hours at 85 °C with specified limits for capacitance change, tan δ and leakage current after endurance testing.
• Operating Temperature Range: −40 °C to 85 °C, suitable for a wide range of general-purpose environments.
• Loss Factor and Leakage: Specified tan δ (DF) of 0.44 measured at 20 °C, 120 Hz, and a leakage current specified at 11,250 µA for this part number.
• Package & Mounting: Radial lead can with dimensions φ22 × 50 mm and lead spacing 10.0 mm (±0.5 mm); available in bulk or bag packing (no terminal forming).
• Compliance: RoHS compliant.

Typical Applications

• DC Power Supply Filtering: Bulk smoothing and reservoir capacitance on 25 V power rails to reduce ripple and support transient load events.
• Switch-Mode Power Supplies: Energy storage and ripple handling for converters where high ripple-current capability at both low and high frequencies is required.
• Industrial and General-Purpose Electronics: Power-rail stabilization and bulk decoupling in general-purpose control and instrumentation equipment.

Unique Advantages

• Large Capacitance in a Compact Can: 15,000 µF in a φ22 × 50 mm package delivers substantial energy storage where board space is constrained.
• Designed for High Ripple Environments: Specified ripple currents at 120 Hz and 10 kHz (3.8 A and 4.37 A) support both line-frequency and switching-frequency applications.
• Long Endurance at Elevated Temperature: 2,000 hours at 85 °C provides a measurable lifetime metric for thermal-stressed designs.
• Radial Lead Form Factor: Through-hole radial leads and standard 10 mm lead spacing simplify prototyping and retrofit into legacy layouts.
• Regulatory Compliance: RoHS compliance supports inclusion in designs targeting restricted-substance requirements.
