UVK1E103MHD

The UVK1E103MHD is a Nichicon UVK 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 electronic applications that require high bulk capacitance and robust ripple handling in a compact radial package.

Key attributes include high capacitance density, polarized construction, and a rated operating temperature range of −40 °C to 85 °C, with a defined endurance of 2000 hours at 85 °C.

Key Features

• High Capacitance: 10,000 µF (10 mF) nominal capacitance for substantial bulk energy storage.
• Rated Voltage: 25 V DC rating suitable for many low‑voltage power rails and general‑purpose circuitry.
• Ripple Current Capability: Low‑frequency ripple current 2.8 A (120 Hz) and high‑frequency ripple current 3.22 A (10 kHz), enabling effective filtering under varying load conditions.
• Loss Characteristics: Specified tangent of loss angle (tan δ) of 0.34 measured at 20 °C, 120 Hz, for predictable dissipation behavior.
• Leakage Current: Specified leakage current of 7,500 µA after initial application of rated voltage.
• Endurance and Temperature Range: Rated for 2000 hours at 85 °C; operating temperature range −40 °C to 85 °C.
• Mechanical & Mounting: Radial lead package with body size φ18 × 40 mm and lead spacing 7.5 mm (±0.5 mm), supplied bulk or bag packed for assembly flexibility.
• Compliance: RoHS compliant.
• Polarized Construction: Polar capacitor design for correct DC orientation in power circuits.

Typical Applications

• General‑Purpose Power Filtering — Provides bulk capacitance and ripple current handling for general‑purpose power rails and decoupling in electronic equipment.
• Energy Storage for Low‑Voltage Systems — 10,000 µF at 25 V supports temporary energy buffering where high capacitance is required within a compact radial package.
• Industrial and Consumer Electronics — Suitable for applications that require durable performance across −40 °C to 85 °C and an endurance rating of 2000 hours at 85 °C.

Unique Advantages

• Large Capacitance in a Compact Can: 10,000 µF in a φ18 × 40 mm body offers significant energy density for space‑conscious board designs.
• Defined Ripple Performance: Specified low‑ and high‑frequency ripple currents (2.8 A @ 120 Hz, 3.22 A @ 10 kHz) let designers size capacitors to meet real ripple and smoothing requirements.
• Engineered Endurance: 2000‑hour life at 85 °C provides predictable aging characteristics for maintenance planning and long‑term deployments.
• Series Heritage: Part of Nichicon’s UVK series noted for miniature sizing (one rank smaller than UVR), helping reduce board footprint without sacrificing capacitance.
• Flexible Packaging: Available in bulk (no terminal forming) or bag packing to fit assembly and procurement preferences.
• Regulatory Compliance: RoHS compliance supports regulatory and supply‑chain requirements.
