UKW1J220MDD

The UKW1J220MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, engineered for audio and AV equipment. It combines a 22 µF capacitance with a 63 V rating in a compact φ5 × 11 mm can, offering low dissipation and specified ripple handling for sound-focused power and signal circuits.

Key Features

• Capacitance & Voltage: 22 µF rated capacitance with a 63 V voltage rating and tolerance of −20% to +20% for predictable charge storage in audio circuits.
• Low Dissipation Factor (tan δ): tanδ = 0.10 measured at 20°C, 120 Hz (rated voltage), supporting low-loss operation in signal-sensitive paths.
• Ripple Current Handling: Low-frequency ripple current 100 mA at 120 Hz and high-frequency ripple current 200 mA at 10 kHz, specified for power conditioning in audio applications.
• Leakage Current: Specified leakage current of 41.58 µA, suitable for stable bias conditions in amplifier and AV circuitry.
• Endurance: Rated for 2000 hours at 85°C with defined endurance criteria for capacitance, tanδ and leakage current after test.
• Mechanical & Mounting: Radial lead, polarized can in φ5 × 11 mm (L: 1.1 × D: 0.5 cm) with 2.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Operating Range & Compliance: Operating temperature −40°C to +85°C and RoHS compliant as specified for the UKW series.

Typical Applications

• Audio and AV Equipment: Designed for use in consumer and professional audio circuits where the UKW series is specified for harmonious sound quality.
• Through-Hole PCB Designs: Radial-lead format and compact φ5×11 mm can make it suitable for space-constrained through-hole layouts in audio devices.
• Power Conditioning in Audio Circuits: Specified ripple handling at low and high frequencies supports smoothing and decoupling tasks in audio power supplies.

Unique Advantages

• Audio-focused Electrolyte Development: Part of the UKW series developed for sound quality, aligning material choice with audio performance priorities.
• Low Loss at Signal Frequencies: tanδ = 0.10 at 120 Hz reduces energy dissipation in signal-path and coupling applications.
• Dual-frequency Ripple Specification: Explicit ripple current ratings at 120 Hz and 10 kHz provide clarity for both power-supply and higher-frequency decoupling requirements.
• Compact, Serviceable Form Factor: φ5 × 11 mm radial can with 2 mm lead spacing fits dense through-hole boards while remaining easy to handle in assembly and repairs.
• Elevated Temperature Endurance: 2000 hours at 85°C defines expected long-term behavior under elevated operating conditions.
• RoHS Compliant: Meets the RoHS directive as specified for the UKW series, supporting regulatory requirements for electronic assemblies.
