UKW1J222MHD

The UKW1J222MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, optimized for audio and AV equipment. It delivers 2.2 mF capacitance at a 63 V rating with a ±20% tolerance and is designed for applications that require substantial bulk capacitance and reliable ripple-handling at audio frequencies.

Key value propositions include high ripple current capability at both low and high frequencies, a low loss tangent at 120 Hz, and a 2000-hour endurance rating at 85°C—features that support stable power delivery and long-term reliability in audio systems.

Key Features

• Capacitance & Voltage  2.2 mF (2200 µF) rated at 63 V with ±20% tolerance, providing substantial bulk energy storage for power rails.
• Low Loss at Audio Frequencies  tan δ = 0.12 measured at 20°C, 120 Hz, indicating controlled dissipation at audio-range frequencies.
• High Ripple Current Capability  Rated ripple current of 2.2 A at 120 Hz (low frequency) and 2.53 A at 10 kHz (high frequency) to handle dynamic loads and reduce heating under real-world audio signal conditions.
• Leakage Current  Specified leakage current: 4158 µA, for designers to account for standby consumption and bias conditions.
• Endurance & Temperature Range  2000 hours life at 85°C and an operating temperature range of −40°C to +85°C for sustained performance in typical AV environments.
• Radial Package & Mechanical Data  Radial lead, can package with dimensions φ18 × 35.5 mm and 7.5 mm lead spacing; supplied in bulk (no terminal forming) / bag packing for production handling.
• Audio-Optimized Series  Part of the UKW series, developed for harmonious sound quality and targeted at AV/audio equipment; RoHS compliant.

Typical Applications

• Audio and AV Equipment  Power supply smoothing and decoupling in amplifiers, preamplifiers, and other signal-chain electronics where stable bulk capacitance is required.
• Power Supply Rails  Bulk energy storage and ripple absorption on DC rails in consumer and professional audio systems.
• High-Load Audio Modules  Modules and subassemblies that experience dynamic current draw, benefiting from the part’s rated ripple-current performance.

Unique Advantages

• Large Bulk Capacitance: 2.2 mF provides substantial energy reservoir for smoothing and transient support in audio power systems.
• Audio-Focused Loss Characteristics: Measured tan δ = 0.12 at 120 Hz aligns the part’s electrical behavior with audio-frequency performance needs.
• Dual-Frequency Ripple Capability: Rated ripple current values at both 120 Hz and 10 kHz allow designers to specify a single capacitor for low- and high-frequency ripple environments.
• Durability at Elevated Temperature: 2000-hour endurance at 85°C offers predictable aging characteristics for long-term designs.
• RoHS Compliant & Series-Level Optimization: Meets RoHS requirements and benefits from the UKW series’ audio-oriented electrolyte and construction choices.
• Production-Ready Packaging: Bulk/bag packing and mass production status support volume assembly and procurement planning.
