UKW1A222MPD

The UKW1A222MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, designed for audio and AV equipment. It provides 2200 µF capacitance at a 10 V rating in a compact φ10 × 20 mm can, delivering high ripple handling and long-term endurance for audio power and filtering applications.

Key Features

• Electrical Performance — 2200 µF nominal capacitance (2.2 mF) with tolerance of -20% to 20%, rated at 10 V.
• Low-loss Audio Character — Measured tanδ of 0.26 (20°C, 120 Hz) and a leakage current specification of 660 µA, supporting stable performance in audio signal and power stages.
• High Ripple Capability — Low-frequency ripple current of 1.05 A at 120 Hz and high-frequency ripple current of 1.208 A at 10 kHz, enabling effective smoothing and decoupling in power rails for audio circuits.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies and hand or wave soldering workflows.
• Temperature & Endurance — Rated operating range of -40°C to +85°C with an endurance of 2000 hours at 85°C, suitable for typical AV and consumer audio environments.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Audio Equipment — Designed for use in audio circuits where large capacitance and low loss are needed for power supply smoothing and energy reservoir functions.
• AV Systems — Suited to AV components that require compact filtering capacitors with measurable ripple-handling at both low and high frequencies.
• Power Supply Decoupling in Audio Stages — Supports decoupling and local energy delivery for preamplifiers, power amplifiers, and other audio power subsystems.

Unique Advantages

• Audio-tuned Electrolyte — Part of the UKW series developed for audio equipment, providing an electrolyte formulation intended to balance sound-related performance metrics.
• High Ripple Margin — Rated ripple currents of 1.05 A (120 Hz) and 1.208 A (10 kHz) give margin for smoothing pulsating supplies and handling dynamic audio loads.
• Compact Footprint — φ10 × 20 mm can with 5 mm lead spacing minimizes PCB area while delivering 2200 µF of capacitance for space-constrained designs.
• Extended Endurance — 2000 hours at 85°C endurance supports reliable operation over sustained elevated-temperature use in AV equipment.
• RoHS Compliant & Production-ready — RoHS compliance and mass-production status simplify procurement and regulatory alignment for manufactured products.

Why Choose UKW1A222MPD?

UKW1A222MPD targets designers and OEMs building audio and AV equipment who need a compact, high-capacitance aluminum electrolytic with measured low-loss characteristics and solid ripple performance. Its combination of 2200 µF at 10 V, measurable tanδ, and specified ripple currents makes it straightforward to evaluate against power-supply and decoupling requirements in audio signal chains.

This capacitor is appropriate for designs that demand a small can footprint, clear endurance data (2000 h at 85°C), and straightforward through-hole mounting. Its RoHS compliance and bulk/bag packaging options support production-scale assembly and environmental regulatory needs.
