UKL1C220KDD

The UKL1C220KDD is a miniature radial aluminum electrolytic capacitor in Nichicon’s UKL series, offering a 22 µF capacitance with a 16 V rating in a compact φ5 × 11 mm can. Designed for polarized applications in audio circuitry, it combines low leakage, modest ripple capability at both low and high frequencies, and a small radial-lead package for space-constrained boards.

Key value propositions include low leakage current (0.704 µA), a low loss tangent (tanδ = 0.12 at 20°C, 120 Hz), and endurance rated to 2000 hours at 85°C, making it suitable where stable bias and compact form factor are priorities.

Key Features

• Electrical — 22 µF, 16 V, Polarized 22 µF capacitance with ±10% tolerance and a 16 V rated voltage for polarized applications.
• Low Leakage Current Specified leakage current of 0.704 µA, supporting stable DC bias in sensitive circuits.
• Low Loss (tanδ) Tangent of loss angle (tanδ) = 0.12 measured at 20°C and 120 Hz, indicating low dielectric losses for audio-frequency use.
• Ripple Current Capability Rated ripple currents of 85 mA at 120 Hz (low frequency) and 170 mA at 10 kHz (high frequency) for decoupling and filtering across audio-band and higher-frequency environments.
• Compact Radial Can Package Small footprint with size φ5 × 11 mm and 2.0 mm lead spacing (±0.5 mm tolerance), supplied as a radial lead, can-style package for through-hole mounting.
• Operating Range & Endurance Rated for operation from −40°C to +85°C with an endurance of 2000 hours at 85°C.
• Packaging & Compliance Available in bulk or bag packing and RoHS compliant for regulatory alignment.

Typical Applications

• Audio — Power decoupling and supply smoothing Low leakage and defined ripple current ratings make this capacitor suitable for maintaining stable bias and smoothing in audio power rails.
• Audio — Compact circuit boards The φ5 × 11 mm radial can and 2.0 mm lead spacing suit space-constrained audio modules and daughterboards.
• Audio — General-purpose audio circuitry Polarized aluminum electrolytic capacitor for use in consumer and professional audio electronics where 22 µF/16 V performance is required.

Unique Advantages

• Low leakage for bias stability: The specified 0.704 µA leakage minimizes DC drift and helps preserve operating points in audio circuits.
• Low dielectric loss: tanδ = 0.12 at 120 Hz reduces loss in the audio band, helping maintain signal integrity and efficiency.
• Dual-frequency ripple capability: Rated ripple currents at both 120 Hz and 10 kHz provide usable performance across low- and high-frequency decoupling needs.
• Compact radial package: φ5 × 11 mm can and narrow 2.0 mm lead spacing enable high-density PCB layouts and straightforward through-hole assembly.
• Endurance at elevated temperature: 2000 hours at 85°C supports sustained operation in typical electronics enclosures and environments.
• RoHS compliant and practical packing: RoHS compliance and availability in bulk or bag packing aid regulatory compliance and production workflow.
