UKL1A472MHD

The UKL1A472MHD is a low-leakage aluminum electrolytic capacitor in a radial-lead can, specified at 4700 µF (4.7 mF) and 10 V. It delivers high bulk capacitance with controlled leakage and rated ripple handling for applications where stable storage and filtering of energy are required.

Key mechanical and reliability attributes include a φ16 × 35.5 mm can, 7.5 mm lead spacing, an operating temperature range of −40 °C to 85 °C, and a rated endurance of 2000 hours at 85 °C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance with ±20% tolerance at 10 V rated voltage, providing significant bulk energy storage in a compact radial package.
• Low Leakage Current — Specified leakage current is 94 µA, supporting circuits that require minimized self-discharge and leakage-related drift.
• Ripple Current Capability — Low-frequency ripple current of 1.65 A (120 Hz) and high-frequency ripple current of 1.8975 A (10 kHz) to handle AC ripple in filtering and decoupling roles.
• Endurance & Temperature Range — Rated for 2000 hours at 85 °C with an operating range of −40 °C to 85 °C, suitable for prolonged use at elevated temperatures within this rating.
• Radial Through-Hole Package — φ16 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for straightforward through-hole PCB assembly.
• Polarized — Standard polarized aluminum electrolytic construction for bulk filtering and energy reservoir applications.
• RoHS Compliant — Manufactured to meet RoHS directive requirements.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to support common PCB assembly workflows.

Typical Applications

• Audio equipment — Provides bulk capacitance and low leakage for power supply smoothing and decoupling in audio circuits where stable DC rails and minimal leakage are important.
• Power filtering — Used in power-supply output filters and reservoirs to manage ripple and transient loads within the capacitor’s rated ripple currents.
• Through-hole PCB designs — Suited to designs that require a rugged radial-lead capacitor with defined lead spacing for manual or wave-solder assembly.

Unique Advantages

• High bulk capacitance in a compact can — 4700 µF in a φ16 × 35.5 mm package reduces board space compared with multiple smaller capacitors while delivering required energy storage.
• Measured low leakage — 94 µA leakage current helps maintain DC stability and reduces parasitic discharge in sensitive circuits.
• Qualified ripple handling — Specified low- and high-frequency ripple ratings let designers size the capacitor for both mains-frequency and higher-frequency ripple conditions.
• Rated endurance at elevated temperature — 2000 hours at 85 °C provides predictable lifetime behavior when operated within specified thermal limits.
• Through-hole robustness — Radial-lead, polarized can style is robust for mechanical and thermal stresses common in consumer and pro-audio assemblies.
• Regulatory compliance — RoHS compliance supports use in products targeting restricted-substance requirements.
