UKL1C100KDD

The UKL1C100KDD is a low-leakage aluminum electrolytic capacitor in a compact radial-lead can. It provides 10 µF capacitance at a 16 V rating with a ±10% tolerance, optimized for audio and other precision analog applications that benefit from minimal leakage and stable performance across a wide temperature range.

Engineered for PCB-mounted radial assemblies, this part combines low leakage (0.32 µA), defined ripple current capability, and a small footprint (φ5 × 11 mm) to simplify designs where space and bias stability matter.

Key Features

• Low Leakage Current — Specified leakage current of 0.32 µA after rated voltage application, helping preserve bias conditions in sensitive circuits.
• Electrical Ratings — 10 µF capacitance at 16 V with ±10% tolerance (K), suitable for precision analog and audio uses.
• Ripple Current Performance — Low-frequency ripple current 55 mA (120 Hz) and high-frequency ripple current 110 mA (10 kHz), supporting smoothing and decoupling where moderate ripple is present.
• Temperature and Endurance — Rated operating range of −40 °C to +85 °C with endurance specified as 2000 hours at 85 °C, providing predictable life characteristics under rated conditions.
• Compact Radial Package — φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm), ideal for dense PCB layouts and through-hole assembly processes.
• Polarized Type — Radial polarized capacitor for DC applications requiring electrolytic biasing.
• RoHS Compliant — Meets RoHS requirements as specified in the product information.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to fit different procurement and assembly workflows.

Typical Applications

• Audio — Low leakage and 10 µF capacitance make the UKL1C100KDD suitable for audio circuits where preserving bias and minimizing drift are important.
• Analog Signal Conditioning — Compact size and defined leakage characteristics support sensitive analog front-ends that require stable DC conditions.
• Power Filtering for Small Modules — Ripple current ratings and radial format provide reliable smoothing and decoupling in compact power stages and module-level supplies.

Unique Advantages

• Minimized bias loss: The 0.32 µA leakage current helps maintain DC operating points in precision and audio circuits over time.
• Compact footprint: φ5 × 11 mm can and 2.0 mm lead spacing allow tight placement on boards, saving PCB area in dense assemblies.
• Clear endurance specification: Rated for 2000 hours at 85 °C, enabling predictable life planning for designs operating at elevated temperatures.
• Frequency-aware ripple handling: Separate low- and high-frequency ripple current ratings (55 mA / 110 mA) provide guidance for use across a range of ripple environments.
• Polarity and mounting certainty: Radial, polarized can format simplifies through-hole assembly and reduces placement ambiguity.
• Regulatory compliance: RoHS status is documented for use in regulated product lines.
