UKL1H6R8MDD

The UKL1H6R8MDD is a miniature aluminum electrolytic capacitor from Nichicon’s UKL series, configured as a radial-lead, polarized capacitor. It delivers 6.8 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing.

Designed for audio and other compact electronic equipment, the electrode and construction emphasize low leakage current and stable AC performance (tan δ = 0.08 measured at 20°C, 120 Hz). This part is RoHS compliant and has a specified endurance of 2000 hours at 85°C. Note: this product is End Of Life.

Key Features

• Capacitance and Tolerance — 6.8 µF nominal capacitance with tolerance of -20%~20%.
• Rated Voltage — 50 V working voltage suitable for mid‑voltage rails.
• Low Leakage — Specified leakage current of 0.68 µA; part of Nichicon’s low leakage-current UKL series.
• Low Loss (tan δ) — tan δ = 0.08 measured at 20°C, 120 Hz, at the 50 V rating for improved AC behavior in signal and power paths.
• Ripple Current Capability — Low-frequency ripple current 55 mA (120 Hz) and high-frequency ripple current 110 mA (10 kHz), supporting power-conditioning and decoupling tasks.
• Thermal and Endurance — Operating temperature range -40°C to 85°C with a rated life of 2000 hours at 85°C.
• Mechanical / Mounting — Radial lead, polarized can package; size φ5 × 11 mm, lead spacing 2.0 mm (±0.5 mm).
• Packaging & Compliance — Available in bulk or bag packing; RoHS compliant.

Typical Applications

• Audio Equipment — Suited for audio electronics where compact, low‑leakage capacitors are required for power smoothing and signal coupling.
• Compact Power Supplies — Use for local decoupling and energy storage on mid‑voltage rails in space‑constrained boards.
• General Purpose Electronics — Small‑form-factor projects requiring polarized electrolytic capacitance with defined ripple and temperature performance.

Unique Advantages

• Low Standby Loss: The low leakage current specification (0.68 µA) reduces quiescent power loss in standby or low‑power systems.
• Stable AC Performance: A measured tan δ of 0.08 at 20°C/120 Hz indicates controlled dissipation for improved audio and AC‑coupled performance.
• Compact Footprint: φ5 × 11 mm can and 2 mm lead spacing enable tight board layouts and use in small assemblies.
• Broad Operating Range: Rated for -40°C to 85°C with 2000 hours endurance at 85°C for consistent operation in typical commercial environments.
• Practical Ripple Handling: Defined ripple current ratings at both low and high frequencies help match the component to real‑world supply and decoupling needs.
• Regulatory Compliance: RoHS compliance supports deployments that require restricted‑substance conformance.

Why Choose UKL1H6R8MDD?
