UKL0J471KPD

The UKL0J471KPD is a Nichicon UKL series aluminum electrolytic capacitor in a radial lead, can-style package. It delivers 470 µF capacitance at 6.3 V with low leakage characteristics and is targeted for audio applications where compact, polarized bulk capacitance is required.

Key technical strengths include a compact φ10 × 12.5 mm case, low leakage current (5.922 µA, case size φ10 × 12.5 after 1 minute at 20°C), defined ripple-current ratings for both low and high frequencies, and a 2000-hour endurance rating at 85°C. Note: this product is listed as End Of Life; the UKL series documentation indicates the series is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 6.3 V with ±10% tolerance (K).
• Low Leakage Current — Specified leakage current of 5.922 µA (φ10 × 12.5 case, after 1 minute at 20°C), supporting low idle loss in polarized applications.
• Ripple Current Handling — Rated low-frequency ripple current of 390 mA at 120 Hz and high-frequency ripple current of 585 mA at 10 kHz, enabling reliable smoothing and decoupling across audio-band and higher frequencies.
• Endurance & Temperature Range — 2000 hours at 85°C endurance rating and an operating temperature range of −40°C to 85°C for sustained performance in temperature-varying environments.
• Package & Mounting — Radial lead can, φ10 × 12.5 mm size with 5 mm lead spacing and polarized orientation for through-hole mounting and compact board-level integration.
• Loss Characteristics — Specified tan δ of 0.18 (max.) for the φ10 × 12.5 case at 6.3 V, 120 Hz, 20°C, supporting predictable dissipation behavior.
• Regulatory — RoHS compliant.

Typical Applications

• Audio equipment — Provides bulk capacitance and low leakage for power supply smoothing and decoupling in audio circuits where stable DC bias and low loss are important.
• Portable audio devices — Compact φ10 × 12.5 mm radial package suited to space-constrained boards requiring polarized energy storage.
• Audio signal support — Useful where defined ripple-current capability and low loss (tan δ) contribute to consistent audio performance.

Unique Advantages

• Low idle leakage: The measured leakage of 5.922 µA (φ10 × 12.5 case) minimizes parasitic current draw in standby conditions.
• Frequency-aware ripple ratings: Separate low-frequency (390 mA at 120 Hz) and high-frequency (585 mA at 10 kHz) ripple-current specifications allow designers to match the capacitor to both supply and switching-frequency environments.
• Compact through-hole form factor: φ10 × 12.5 mm radial can with 5 mm lead spacing delivers a small footprint and straightforward through-hole assembly.
• Designed endurance: 2000 hours at 85°C provides a measurable lifetime metric for thermal-stressed applications.
• Predictable dissipation: Specified tan δ value supports predictable heating and loss calculations in design validation.
• RoHS compliant: Meets RoHS requirements for systems constrained by environmental directives.
