UVK1H100MDD

The UVK1H100MDD is a miniature aluminum electrolytic capacitor from Nichicon’s UVK series. It provides 10 µF capacitance at a 50 V rating in a compact φ5 × 11 mm radial can with 2.0 mm lead spacing, designed for general-purpose board-level use.

Engineered for dependable smoothing and decoupling, this polarized radial-lead capacitor offers low leakage (15 µA), controlled loss (tanδ = 0.12 at 20 °C, 120 Hz) and rated endurance of 2000 hours at 85 °C, making it suitable for a wide range of general-purpose electronic applications while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 10 µF rated capacitance at 50 V with tolerance ±20% (–20% to +20%).
• Compact Radial Package — Miniature φ5 × 11 mm aluminum can in a radial-lead format with 2.0 mm lead spacing (lead spacing tolerance ±0.5 mm), suited for through-hole board mounting.
• Low Loss & Leakage — Tangent of loss angle (tanδ) of 0.12 measured at 20 °C and 120 Hz, and leakage current specified at 15 µA for stable performance in low-leakage designs.
• Ripple Current Capability — Low-frequency ripple current of 60 mA at 120 Hz and high-frequency ripple current of 120 mA at 10 kHz to support smoothing and decoupling tasks across frequency ranges.
• Temperature & Endurance — Operating temperature range from –40 °C to +85 °C with an endurance rating of 2000 hours at 85 °C.
• Polarized, General-Purpose Use — Polarized construction for circuit power applications and general-purpose board-level filtering.
• Environmental Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Power supply smoothing — Provides bulk smoothing and ripple reduction on low- to mid-voltage rails up to 50 V, leveraging the part’s ripple-current ratings.
• Decoupling and local energy storage — Useful for board-level decoupling where compact size and low leakage help maintain stable supply voltages.
• Auxiliary and control circuits — Fits into control and support circuitry requiring a compact radial electrolytic with a reliable endurance rating and wide operating temperature range.

Unique Advantages

• Miniature form factor: φ5 × 11 mm radial can saves PCB space while providing a standard through-hole mounting option.
• Balanced electrical performance: 10 µF at 50 V with moderate tanδ and low leakage for stable performance in general-purpose electronics.
• Frequency-range ripple handling: Specified ripple currents at both 120 Hz and 10 kHz cover common low- and high-frequency smoothing needs.
• Wide temperature tolerance and defined endurance: –40 °C to +85 °C operation and 2000 hours at 85 °C supports reliable service in varied environments.
• RoHS compliant: Meets RoHS directive requirements for environmentally conscious designs.
• Simple procurement and handling: Offered in bulk or bag packing for flexible stocking and assembly workflows.
