UKL1A470MDD

The UKL1A470MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, designed for low leakage current performance. With a 47 µF capacitance at a 10 V rating, compact φ5 × 11 mm can size, and radial mounting, it is targeted at audio applications where low-loss filtering and compact decoupling are required.

Key electrical characteristics include a low dissipation factor (tanδ = 0.15 at 20°C, 120 Hz), low measured leakage current, and defined ripple current capability across low and high frequencies—supporting reliable performance in constrained, signal-sensitive designs.

Key Features

• Low Leakage Current  Standard UKL-series low leakage construction; measured leakage current specified at 0.94 µA.
• Electrical Performance  47 µF capacitance with ±20% tolerance and a 10 V rating; polarized design suitable for DC filtering and decoupling in audio circuits.
• Low Dissipation Factor  tanδ = 0.15 (measured at 20°C, 120 Hz), indicating low dielectric loss for improved signal integrity in audio paths.
• Ripple Current Capability  Low-frequency ripple current 110 mA at 120 Hz and high-frequency ripple current 220 mA at 10 kHz, supporting both power-rail smoothing and higher-frequency decoupling.
• Compact Radial Package  Small φ5 × 11 mm can with 2 mm lead spacing (±0.5 mm) for space-conscious through-hole layouts; radial-lead mounting simplifies assembly.
• Reliability and Thermal Range  Rated for operation from –40°C to +85°C with an endurance rating of 2000 hours at 85°C.
• Packaging & Compliance  Available in bulk (no terminal forming) or bag packing; RoHS-compliant.

Typical Applications

• Audio  Targeted for audio circuitry where low leakage and low dissipation factor help maintain signal fidelity for coupling, decoupling, and power-rail smoothing.

Unique Advantages

• Low leakage for stable biasing: Measured leakage current of 0.94 µA helps preserve DC bias conditions in sensitive audio stages.
• Low dielectric loss: tanδ = 0.15 at 120 Hz reduces power dissipation and improves audio signal quality compared to higher-loss capacitors.
• Dual-frequency ripple handling: Rated ripple currents at 120 Hz and 10 kHz (110 mA and 220 mA) enable effective smoothing across both low and high ripple components.
• Compact through-hole form factor: φ5 × 11 mm radial can and 2 mm lead spacing provide a small footprint for legacy PCBs and space-constrained designs.
• Designed for elevated-temperature endurance: 2000 hours at 85°C offers predictable lifetime performance for designs exposed to sustained operating temperatures within the specified range.
• RoHS-compliant supply chain: Meets RoHS requirements for use in regulated markets.
