UKL1C681KHD

The UKL1C681KHD is a low-leakage aluminum electrolytic capacitor in a radial-lead can, rated 680 µF at 16 V with ±10% tolerance. It targets audio and other electronics applications that require stable capacitance, measurable ripple handling, and a compact φ12.5 × 20 mm package with 5 mm lead spacing.

Key electrical characteristics include low leakage current, defined loss tangent, and rated ripple currents at both low and high frequencies. This part is RoHS compliant. Note: this product is marked End of Life and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 16 V with ±10% tolerance for predictable energy storage and decoupling.
• Low Leakage — Specified leakage current of 21.76 µA to minimize leakage-related losses in sensitive circuits.
• Loss Tangent (tan δ) — tanδ of 0.14, providing a quantifiable dissipation factor for designers assessing AC performance.
• Ripple Current Capability — 730 mA at 120 Hz (low frequency) and 1.095 A at 10 kHz (high frequency) to support filtering and smoothing under AC ripple conditions.
• Lifetime & Temperature Range — Rated lifetime of 2000 hours at 85°C and an operating temperature range of −40°C to +85°C.
• Package & Mounting — Radial lead, polar aluminum can (φ12.5 × 20 mm), 5 mm lead spacing; supplied in bulk/bag packaging for volume assembly.
• Compliance — RoHS compliant, suitable for environments requiring lead-free materials.

Typical Applications

• Audio Electronics — Use in audio power supply filtering and decoupling where low leakage and controlled ripple performance are important.
• General Power Filtering — Local energy storage and smoothing in compact DC circuits that fit a φ12.5 × 20 mm radial can.
• Embedded Systems — Bulk decoupling in small form-factor boards requiring polarized electrolytic capacitors with measurable endurance at 85°C.

Unique Advantages

• Measurable Low Leakage: A specified leakage current of 21.76 µA provides a clear baseline for designs sensitive to standby or quiescent currents.
• Defined AC Performance: Tangent of loss angle (tanδ 0.14) and published ripple currents at 120 Hz and 10 kHz let engineers evaluate AC losses and thermal loading precisely.
• Compact Radial Can: φ12.5 × 20 mm size with 5 mm lead spacing delivers a small footprint for board-level power filtering while retaining useful capacitance.
• Endurance Rating: 2000 hours at 85°C provides a documented life expectancy for thermal stress planning and component selection.
• RoHS Compliance: Material compliance simplifies use in lead-free assemblies and regulated markets.
