UKL1C472MHD

The UKL1C472MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKL low-leakage series. It provides high capacitance (4.7 mF / 4700 µF) at a 16 V rating, optimized for audio applications requiring bulk energy storage and low self-discharge.

Key attributes include a compact can package (φ18 × 35.5 mm), low leakage characteristics, measurable ripple-current capability across low and high frequencies, and a rated endurance of 2000 hours at 85°C.

Key Features

• High Capacitance — 4700 µF (4.7 mF) capacitance provides substantial energy storage for power-supply smoothing and bulk decoupling in low-voltage audio circuits.
• Rated Voltage & Tolerance — 16 V rated voltage with ±20% capacitance tolerance (-20% ~ 20%), enabling designers to size capacitance for typical 12–16 V systems.
• Low Leakage — Low leakage-current design with a measured leakage current of 150.4 µA under specified conditions, supporting stable bias and low self-discharge.
• Loss Tangent (tan δ) — tanδ = 0.2 measured at 20°C, 120 Hz for predictable AC loss behavior in signal and power circuits.
• Ripple Current Capability — Rated low-frequency ripple current of 1.82 A at 120 Hz and high-frequency ripple current of 2.093 A at 10 kHz for handling both mains- and high-frequency switching noise.
• Endurance & Temperature Range — 2000 hours endurance at 85°C with operating temperature from −40°C to +85°C for stable performance in a range of environments.
• Package & Mounting — Radial-lead can, dimensions φ18 × 35.5 mm and lead spacing 7.5 mm (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Audio systems — Bulk storage and smoothing in audio power supplies where high capacitance and low leakage help maintain stable DC rails and reduce hum.
• Audio amplifiers — Decoupling and reservoir capacitor for amplifier supply stages benefiting from the 4700 µF capacitance and rated ripple-current handling.
• Audio electronics — General-purpose bulk filtering and power conditioning in consumer and professional audio gear operating within −40°C to +85°C.

Unique Advantages

• Substantial energy density: 4700 µF at 16 V provides large bulk capacitance in a compact φ18 × 35.5 mm can, reducing external capacitor count.
• Measured ripple performance: Specified ripple currents of 1.82 A (120 Hz) and 2.093 A (10 kHz) give designers quantifiable margins for both low- and high-frequency noise management.
• Low leakage current: Measured leakage of 150.4 µA minimizes DC loss and helps maintain bias levels in sensitive audio circuits.
• Designed for sustained operation: 2000 hours endurance at 85°C provides predictable lifetime behavior for equipment deployed in normal commercial environments.
• Through-hole convenience: Radial-lead package with 7.5 mm lead spacing supports traditional PCB mounting and straightforward assembly.
• Regulatory readiness: RoHS compliance supports environmental and regulatory requirements for electronic assemblies.
