UKL1J471KHD

The UKL1J471KHD from Nichicon is a low-leakage aluminum electrolytic capacitor in a radial-lead can designed for audio applications. It delivers 470 µF capacitance at a 63 V rating with a compact φ16 × 25 mm package and polarized radial mounting.

Engineered for circuits that require low leakage and robust ripple handling, this device combines a 470 µF capacitance, ±10% tolerance, and specified ripple current performance at both low and high frequencies for stable operation in audio power and signal circuits.

Key Features

• Core Electrolytic Performance — 470 µF capacitance with ±10% tolerance, rated at 63 V for DC energy storage and decoupling in audio circuits.
• Low Leakage — Specified leakage current of 59.22 µA, reducing standby loss and drift in bias-sensitive audio stages.
• Ripple Current Capability — Low-frequency ripple current of 850 mA at 120 Hz and high-frequency ripple current of 1.275 A at 10 kHz to handle both power-supply smoothing and high-frequency load demands.
• Endurance and Temperature Range — Rated for 2000 hours at 85°C with an operating temperature range of –40°C to +85°C for predictable life under specified thermal stress.
• Package & Mounting — Radial-lead, polarized can in a φ16 × 25 mm (L: 2.5 × D: 1.6 cm) package with 7.5 mm lead spacing (±0.5 mm), suitable for through-hole assemblies.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to match assembly and procurement preferences.
• RoHS Compliance — Conforms to RoHS requirements for environmental compliance in electronic assemblies.

Typical Applications

• Audio Power Supplies — Bulk energy storage and smoothing for amplifier and preamplifier power rails, leveraging 470 µF capacitance and 63 V rating.
• Audio Amplifiers — Supply decoupling and reservoir capacitance where low leakage helps maintain DC bias stability in sensitive audio stages.
• Signal Conditioning — Coupling and filtering in audio signal paths where stable capacitance and low leakage improve long-term performance.

Unique Advantages

• Reduced Standby Drift: Low leakage current (59.22 µA) helps preserve circuit bias and reduces loss in low-current audio circuits.
• Broad Ripple Handling: Specified ripple ratings at 120 Hz (850 mA) and 10 kHz (1.275 A) enable reliable performance across both low- and high-frequency supply conditions.
• Compact Through-Hole Form: φ16 × 25 mm radial can with 7.5 mm lead spacing fits conventional PCB layouts while providing significant capacitance per volume.
• Designed for Extended Operation: 2000-hour endurance at 85°C provides predictable lifecycle behavior under rated conditions.
• Polarized Electrolytic Construction: Suitable for DC applications requiring larger capacitance values than typical film capacitors.
• Environmentally Compliant: RoHS conformity supports regulatory requirements for commercial and consumer electronics.
