UKL0J681KPD

The UKL0J681KPD is an aluminum electrolytic capacitor in a radial lead can optimized for low leakage current. It delivers 680 µF capacitance at a 6.3 V rating in a compact φ10 × 16 mm package with radial leads.

Designed for audio and other electronic applications that require bulk capacitance with controlled leakage and measurable ripple handling, the device combines low leakage (8.568 µA), measurable ripple current capability, and 2000 hours endurance at 85°C to support sustained operation in constrained board spaces.

Key Features

• Capacitance & tolerance — 680 µF nominal capacitance with ±10% tolerance (120 Hz, 20°C), providing stable energy storage for power rails and filtering.
• Rated voltage — 6.3 V DC rating suitable for low-voltage audio and control circuits.
• Low leakage current — Specified leakage current of 8.568 µA (case size φ10 × 16, measured after 2 minutes at 20°C), minimizing bias loss in standby or low-current conditions.
• Ripple current capability — 480 mA at 120 Hz (low-frequency) and 720 mA at 10 kHz (high-frequency) for handling AC ripple on power rails.
• Endurance and temperature — Rated for 2000 hours at 85°C and an operating temperature range of −40°C to +85°C.
• Package & mounting — Radial lead can, size φ10 × 16 mm (L: 1.6 × D: 1 cm), lead spacing 5.0 mm (±0.5 mm), polarized for straightforward board placement.
• Electrical loss — tan δ up to 0.21 for the φ10 × 16 case at 6.3 V, enabling designers to account for dissipation in AC environments.
• Compliance & packing — RoHS compliant; available in bulk (no terminal forming) or bag packing options.

Typical Applications

• Audio electronics — Bulk energy storage and ripple handling for audio power rails, leveraging 680 µF capacitance and rated ripple current values to support clean power delivery.
• Board-level power filtering — Compact φ10 × 16 package and radial leads make this capacitor suitable for local decoupling and smoothing in densely populated PCBs.
• Embedded systems and consumer electronics — Operation from −40°C to +85°C and 2000-hour endurance at 85°C support sustained use in general-purpose embedded designs.

Unique Advantages

• Low steady-state leakage — The specified 8.568 µA leakage (φ10 × 16) helps preserve bias voltages and reduces quiescent loss in low-current or standby conditions.
• Dual-frequency ripple capability — Rated ripple currents at 120 Hz (480 mA) and 10 kHz (720 mA) provide predictable performance across low- and high-frequency ripple environments.
• Compact radial form factor — φ10 × 16 mm can and 5.0 mm lead spacing enable high-density placement while maintaining through-hole mounting robustness.
• Durability at elevated temperature — 2000 hours endurance at 85°C gives a defined lifetime metric for thermal-stressed designs.
• Regulatory cleanliness — RoHS compliance supports designs targeting regional environmental directive requirements.
• Multiple packing options — Available in bulk or bag packing to suit prototype runs and volume assembly workflows.
