UKW1V221MPD

The UKW1V221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, optimized for audio and AV equipment. It delivers 220 µF capacitance at a 35 V rating with a compact radial-can package suitable for through-hole mounting.

Designed to support audio circuitry, this capacitor combines a formulation targeted at sound-quality balance with practical power-handling characteristics—notably rated ripple currents and low leakage—making it appropriate for supply smoothing and decoupling in AV systems.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 35 V rating and ±20% tolerance for predictable energy storage and decoupling.
• Audio-oriented Electrolyte — Part of the UKW series developed for a harmonious balance of sound quality, suited for AV equipment and audio applications.
• Low-loss Characteristics — Tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz (35 V), supporting stable AC performance in audio circuits.
• Ripple Current Handling — Low-frequency ripple current 370 mA (120 Hz) and high-frequency ripple current 555 mA (10 kHz) to handle filtering and decoupling across audio-relevant frequencies.
• Leakage and Reliability — Specified leakage current 231 µA and endurance rated to 2000 hours at 85°C for long-term stability under load.
• Compact Radial Package — φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for easy through-hole assembly and retrofit.
• Packaging Options & Production Status — Available in bulk (no terminal forming) or bag packing; product is in mass production.
• Compliance — RoHS compliant.

Typical Applications

• Home and Professional AV Equipment — Power supply smoothing and decoupling where audio characteristics and stable capacitance are required.
• Audio Amplifiers and Preamp Circuits — Local supply filtering and reservoir capacitance to support consistent audio performance.
• Signal and Power Conditioning in Audio Systems — Use in crossover networks and power rails within AV products that benefit from a capacitor tuned for sound balance.

Unique Advantages

• Audio-focused formulation — UKW series electrolyte development explicitly targets a balanced sound signature, making the component a fit for AV-centric designs.
• Measurable low-loss behavior — tan δ of 0.14 at 35 V (120 Hz, 20°C) helps maintain AC performance and reduce heat in audio-frequency applications.
• Broad ripple handling — Specified ripple currents at both low and high frequencies (370 mA at 120 Hz, 555 mA at 10 kHz) support filtering across the audio spectrum.
• Durability under elevated temperature — Endurance rated to 2000 hours at 85°C, providing predictable long-term behavior in typical AV operating environments.
• Compact, through-hole form factor — φ10 × 12.5 mm radial can with 5 mm lead spacing simplifies PCB layout and assembly for retrofit and new designs.
• Regulatory compliance — RoHS compliance supports designs targeting global environmental requirements.
