UKL1E470KED

The UKL1E470KED is a low-leakage aluminum electrolytic capacitor in a radial-lead can, designed for compact board-level power and signal applications. It provides 47 µF capacitance with a ±10% tolerance and a 25 V rated voltage in a φ6.3 × 11 mm package with 2.5 mm lead spacing.

Key attributes include low leakage current, defined ripple current ratings at low and high frequency, a 2000-hour endurance rating at 85°C, and RoHS compliance. Available in bulk or bag packing, this part addresses space-constrained designs that require predictable leakage and ripple performance.

Key Features

• Low Leakage Current  Specified leakage current of 2.35 µA provides reduced standby drain and predictable bias behavior for sensitive circuits.
• Capacitance and Tolerance  47 µF nominal capacitance with ±10% tolerance (K) at 120 Hz and 20°C.
• Voltage Rating  Rated for 25 V operation, suitable for a wide range of low-voltage power rails.
• Ripple Current Performance  Rated low-frequency ripple current of 170 mA at 120 Hz and high-frequency ripple current of 340 mA at 10 kHz, supporting filtering and smoothing duties across frequencies.
• Endurance and Temperature  2000 hours rated life at 85°C with an operating temperature range of −40°C to +85°C.
• Compact Radial Package  Radial lead mounting in a φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm), enabling compact PCB layouts and through-hole assembly.
• RoHS Compliant and Packing Options  Compliant with RoHS; available in bulk (no terminal forming) or bag packing for prototyping and production.

Typical Applications

• Audio  For audio equipment and circuits where low leakage and compact radial packages help maintain signal integrity and reliable power decoupling.

Unique Advantages

• Lower Standby Current  The specified 2.35 µA leakage current reduces idle power draw, helping preserve battery life and minimize bias drift in sensitive circuits.
• Compact Footprint  φ6.3 × 11 mm can and 2.5 mm lead spacing make the part suitable for space-constrained PCB designs while retaining through-hole robustness.
• Broad Ripple Handling  Separate ripple ratings at 120 Hz and 10 kHz (170 mA / 340 mA) give designers clear performance expectations across both power-line and higher-frequency switching environments.
• Predictable Lifetime  2000 hours endurance at 85°C provides a defined reliability target for thermal stress and long-term deployment planning.
• Regulatory Compliance  RoHS compliance supports integration into modern assemblies that require restricted-substance conformance.
• Flexible Packing  Available in bulk or bag packing to match prototyping and production workflows.
