UKL1A680KED

The UKL1A680KED is a radial-lead aluminum electrolytic capacitor in Nichicon's UKL low-leakage series. It provides 68 µF capacitance at a 10 V rating in a compact φ6.3 × 11L can with 2.5 mm lead spacing, targeted for space-constrained board-level power and signal filtering.

Designed for audio applications, this polarized capacitor offers low leakage, presence of defined ripple current performance at both low and high frequencies, and a 2000-hour endurance at 85°C—delivering stable performance for consumer and professional audio circuitry.

Key Features

• Capacitance & Voltage: 68 µF capacitance with a 10 V rated voltage and ±10% tolerance for predictable charge storage and decoupling.
• Low Leakage Current: Part of Nichicon's low leakage UKL series with a measured leakage current of 1.36 µA, helping preserve bias and minimize standby discharge in audio circuits.
• Ripple Current Performance: Rated ripple current of 150 mA at 120 Hz and 300 mA at 10 kHz to support both low-frequency power smoothing and higher-frequency decoupling needs.
• Endurance & Temperature Range: Rated for 2000 hours at 85°C with an operating temperature range of −40°C to 85°C, providing defined lifetime behavior under elevated temperature conditions.
• Compact Radial Package: φ6.3 × 11L can with 2.5 mm lead spacing (±0.5 mm tolerance) and radial lead mounting for straightforward through-hole assembly in compact layouts.
• Regulatory Compliance & Packaging: RoHS-compliant and available in bulk (no terminal forming) or bag packing for straightforward procurement and handling.

Typical Applications

• Audio power supply filtering: Provides low-leakage bulk capacitance for smoothing and stabilizing low-voltage audio power rails.
• Audio preamp and amplifier circuits: Supplies compact decoupling where low leakage preserves DC bias and audio fidelity in signal paths.
• Consumer audio electronics: Fits compact through-hole assemblies for portable or space-constrained audio devices requiring defined ripple handling and endurance.

Unique Advantages

• Low standby discharge: The low leakage current (1.36 µA) reduces unwanted discharge over time, helping maintain bias conditions in audio circuits.
• Balanced ripple capability: Specified ripple current at both 120 Hz and 10 kHz supports filtering across audio-relevant frequencies, enabling cleaner supply rails and reduced noise.
• Compact footprint: Small φ6.3 × 11L can and 2.5 mm lead spacing save board space while remaining compatible with radial through-hole assembly processes.
• Predictable lifetime: 2000 hours at 85°C endurance rating lets designers plan for long-term performance and thermal stress behavior.
• RoHS compliance: Meets RoHS requirements for environmental and regulatory consistency in end products.
