UVZ1E103MRD

The UVZ1E103MRD is a Nichicon UVZ series aluminum electrolytic capacitor in a radial‑lead can, offering 10,000 µF capacitance at a 25 V rating. It is designed for general‑purpose power applications that require high bulk capacitance in a compact φ20 × 40 mm package.

Key attributes include wide operating temperature range (‑55 °C to 105 °C), defined endurance (2000 hours at 105 °C), and RoHS compliance—making it suitable for board‑level power filtering, energy hold‑up and decoupling tasks where robust temperature and ripple performance are important.

Key Features

• High Capacitance and Voltage: 10,000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and smoothing on 25 V rails.
• Ripple Current Performance: Low‑frequency ripple current of 2.15 A (120 Hz) and high‑frequency ripple current of 2.473 A (10 kHz), supporting sustained AC loading in power circuits.
• Wide Temperature Range: Operational from ‑55 °C to 105 °C, enabling use across a broad range of thermal environments.
• Endurance: Rated for 2000 hours at 105 °C with specified limits on capacitance change, tan δ, and leakage after aging.
• Leakage Current: Specified leakage current of 7,500 µA for predictable standby and no‑load behavior.
• Radial Lead Package: φ20 × 40 mm can with 10 mm lead spacing (±0.5 mm) and radial leads for through‑hole mounting and straightforward PCB placement; available in bulk (no terminal forming) and bag packing.
• Regulatory Compliance: RoHS compliant, matching environmental requirements for lead‑restricted applications.

Typical Applications

• Power Supply Filtering: Bulk smoothing and decoupling on 25 V rails where high capacitance and defined ripple handling are required.
• Energy Hold‑up / Backup: Short‑term energy storage for hold‑up circuits and transient absorption in power electronics.
• Industrial Control Electronics: Capacitor for power conditioning in industrial controllers and control panels that operate across wide temperatures.
• General‑Purpose Electronics: Through‑hole radial mounting for repairable boards, prototypes, and designs that require high bulk capacitance in a compact can.

Unique Advantages

• High bulk capacitance in a compact can: 10,000 µF in a φ20 × 40 mm package reduces board area compared with multiple smaller devices.
• Defined ripple handling at multiple frequencies: Rated ripple currents at 120 Hz and 10 kHz provide designers with verified performance across common power spectral components.
• Wide operating temperature and proven endurance: ‑55 °C to 105 °C operation and 2000 hours at 105 °C give confidence for long‑life thermal environments.
• Through‑hole radial format: Radial leads and 10 mm lead spacing enable easy insertion, replacement, and mechanical robustness in assemblies.
• RoHS compliance: Meets lead‑restriction environmental requirements for modern electronics manufacturing.
