UKL0J472MHD

The UKL0J472MHD is a radial-lead aluminum electrolytic capacitor with a nominal capacitance of 4700 µF (4.7 mF) and a rated voltage of 6.3 V. It is part of Nichicon's UKL low-leakage series and is offered in a compact φ16 × 30.5 mm can with 7.5 mm lead spacing.

Designed for audio applications, this polarized capacitor delivers low leakage, robust ripple-current handling at both low and high frequencies, and endurance specified to 2000 hours at 85°C, making it suitable where stable bulk capacitance and low loss are required in compact, through-hole designs.

Key Features

• Capacitance & Voltage – 4700 µF nominal capacitance with a rated voltage of 6.3 V and a tolerance of −20% to +20%.
• Low Leakage Current – Part of the UKL low leakage series; specified leakage current is 59.22 µA (measured at 20°C after specified application time).
• High Ripple-Current Capability – Rated ripple currents of 1500 mA at 120 Hz and 1725 mA at 10 kHz support demanding filtering and decoupling in power stages.
• Loss Characteristics – Tangent of loss angle (tanδ) specified at 0.27 (20°C, 120 Hz), supporting low-loss performance in signal-sensitive circuits.
• Endurance & Temperature Range – Life rating of 2000 hours at 85°C; operating temperature range −40°C to +85°C.
• Package & Mounting – Radial lead, polarized can package; case dimensions φ16 × 30.5 mm with 7.5 mm lead spacing and 0.8 mm lead diameter.
• RoHS Compliant – Meets RoHS directive requirements as indicated in product data.

Typical Applications

• Audio – Suited for audio circuitry where large bulk capacitance, low leakage and reliable ripple handling are required for power filtering and signal stability.

Unique Advantages

• Substantial Bulk Capacitance: 4700 µF provides significant energy storage for smoothing and decoupling in compact through-hole implementations.
• Low Leakage: Measured leakage of 59.22 µA helps maintain bias stability and reduces unwanted discharge in low-current audio circuits.
• Dual-Frequency Ripple Support: Rated ripple currents at both 120 Hz and 10 kHz (1.5 A and 1.725 A respectively) accommodate performance across low- and high-frequency power components.
• Durability in Elevated Temperatures: 2000 hours endurance at 85°C supports longer service life in thermally active enclosures.
• Compact Radial Can: φ16 × 30.5 mm package with standard 7.5 mm lead spacing fits many legacy and repair applications needing through-hole components.
• Regulatory Compliance: RoHS compliance simplifies use in designs targeting restrictive substance requirements.
