UVR1E103MRD

The UVR1E103MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVR series, providing 10,000 µF capacitance at a 25 V rating in a compact φ20×40L can. Designed as a standard series for entertainment electronics and general-purpose applications, it delivers high bulk capacitance for power-supply smoothing and energy storage in through-hole designs.

Key performance characteristics include a wide operating temperature range of −40°C to 85°C, endurance rated for 2000 hours at 85°C, and measurable ripple-current capability for both low and high frequency operation—making it suited to demanding ripple-filtering roles in consumer and industrial electronic equipment.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance with tolerance of −20% to +20% at a rated voltage of 25 V.
• Radial Through‑Hole Package — Φ20×40L aluminum can with radial leads; lead spacing 10 mm with 0.5 mm tolerance for secure PCB mounting.
• Ripple‑Current Capability — Low-frequency ripple current 3.0 A at 120 Hz and high-frequency ripple current 3.45 A at 10 kHz, suitable for smoothing and decoupling in power rails.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C and specified to operate from −40°C to 85°C.
• Leakage & Dissipation — Specified leakage current 7,500 µA and dissipation factor (tanδ) 0.46 measured at 20°C, 120 Hz.
• Packaging Options & Compliance — Available in bulk (no terminal forming) or bag packing; RoHS compliant.

Typical Applications

• Entertainment Electronics — Bulk energy storage and power-supply smoothing in consumer audio and video equipment where the UVR series is commonly used.
• Power Supply Filtering — Primary bulk filter capacitor on 25 V rails to reduce ripple and provide transient energy during load changes.
• General‑Purpose Through‑Hole Designs — Robust radial-lead form factor for repairable, serviceable PCB assemblies and prototype boards.

Unique Advantages

• High Bulk Capacitance: 10,000 µF provides substantial energy storage for smoothing and transient support on low-voltage rails.
• Through‑Hole Robustness: Radial lead can (φ20×40L) and 10 mm lead spacing enable secure mechanical retention and easy manual assembly or rework.
• Dual‑Frequency Ripple Handling: Rated ripple currents at 120 Hz and 10 kHz address both mains-derived and higher-frequency switching noise.
• High‑Temperature Endurance: 2000 hours at 85°C supports long-term operation under elevated-temperature conditions typical in enclosed electronics.
• Measured Electrical Parameters: Specified leakage current and tanδ (measured at 20°C, 120 Hz) provide clear, testable acceptance criteria for design validation.
• Regulatory Compliance: RoHS status ensures compatibility with restricted-substance requirements.
