UKL1V681KHD

The UKL1V681KHD is a miniature, radial‑lead aluminum electrolytic capacitor in Nichicon's UKL series. It delivers 680 µF capacitance at a 35 V rating with a compact φ16 × 25 mm can and 7.5 mm lead spacing for through‑hole mounting.

Designed for audio and related power‑filtering roles, the part combines low leakage (47.6 µA), controlled loss (tan δ = 0.12 at 20°C, 120 Hz) and rated ripple current capability (840 mA at 120 Hz; 1.26 A at 10 kHz) to support stable bias and smoothing in signal and power rails.

Key Features

• Electrical Performance — 680 µF nominal capacitance with ±10% tolerance and 35 V rated voltage, suitable for moderate‑energy storage and decoupling tasks.
• Low Loss & Leakage — Specified tan δ of 0.12 (20°C, 120 Hz) and leakage current of 47.6 µA, helping preserve signal integrity and minimize standby current draw.
• Ripple Current Capability — 840 mA at 120 Hz and 1.26 A at 10 kHz frequency coefficients specified, enabling effective ripple handling across low and high frequency domains.
• Reliability & Endurance — Rated for 2000 hours at 85°C, providing predictable end‑of‑life behavior for thermal stress in typical operating environments.
• Compact Radial Package — φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead termination for easy through‑hole assembly and robust mechanical mounting.
• RoHS Compliant & Packaging — Meets RoHS directive; available in bulk or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Audio Power Supplies — Bulk smoothing and decoupling for amplifier rails where 680 µF at 35 V provides energy reserve and ripple reduction.
• Audio Signal Circuitry — Coupling and bias stabilization in audio front ends and amplifier stages benefitting from low leakage and controlled loss angle.
• Consumer Audio Equipment — Power filtering and transient support in compact, through‑hole assemblies for speakers, receivers, and amplifiers.

Unique Advantages

• Balance of Size and Capacity: 680 µF in a φ16 × 25 mm can offers substantial capacitance for moderate‑voltage audio designs while keeping board space modest.
• Measured Low Leakage: 47.6 µA leakage supports stable bias and long idle periods without excessive current bleed.
• Frequency‑Versatile Ripple Handling: Specified ripple current at both 120 Hz and 10 kHz enables reliable performance across power‑supply and higher‑frequency decoupling needs.
• Through‑Hole Robustness: Radial lead construction and defined 7.5 mm lead spacing simplify assembly and provide strong mechanical retention for larger cans.
• Predictable Endurance: 2000 hours at 85°C gives clear lifetime expectations for thermal stress planning and maintenance cycles.
• Regulatory Compliance: RoHS compliance supports environmental and end‑product regulatory requirements.
