UKW2A470MPD

The UKW2A470MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, engineered for audio equipment and AV applications. It combines a 47 µF capacitance at a 100 V rating with a compact radial-can package to serve audio-focused power and filter circuits that require moderate ripple handling and stable performance over temperature.

Designed with a series electrolyte formulation intended to realize a harmonious balance of sound quality, this part delivers low dissipation (tanδ 0.08 at 100 V, 120 Hz) and specified ripple capability for both low- and high-frequency environments.

Key Features

• Electrical Characteristics 47 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage for circuits requiring higher voltage headroom.
• Low Dissipation tanδ = 0.08 (measured at 20°C, 120 Hz, 100 V) to help minimize dielectric loss in audio signal and power sections.
• Ripple Current Capability Rated low-frequency ripple current 210 mA (120 Hz) and high-frequency ripple current 420 mA (10 kHz) for mixed-frequency audio environments.
• Leakage Current Specified leakage current of 141 µA as provided in the product data.
• Lifecycle and Temperature Range Endurance: 2000 hours at 85°C with performance recovery to 20°C; operating temperature range –40°C to +85°C.
• Compact Radial-can Package Miniature can size φ10 × 12.5 mm with 5 mm lead spacing (±0.5 mm) in a radial lead mounting style for through-hole assembly.
• Series Audio Tuning Part of Nichicon’s UKW series, developed with a new electrolyte to support a harmonious balance of sound quality in AV and audio equipment.
• Environmental Compliance RoHS compliant as stated in the product information.

Typical Applications

• AV Equipment Suited for AV systems where the UKW series' audio-focused electrolyte and 100 V rating provide appropriate performance and headroom.
• Audio Equipment Used in consumer and professional audio assemblies that require a compact radial electrolytic capacitor with controlled dissipation and defined ripple capability.
• Power and Filter Sections Applicable to power-supply filtering and decoupling in audio devices that need 47 µF capacitance and specified ripple current handling at both low and high frequencies.

Unique Advantages

• Audio-optimized electrochemistry: The UKW series electrolyte is developed to support a harmonious balance of sound quality, addressing audio design priorities.
• Balanced electrical performance: 47 µF at 100 V with low tanδ provides a useful combination of capacitance and low dielectric loss for audio circuits.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to quantify performance in both power-supply and higher-frequency audio contexts.
• Compact radial-can form factor: φ10 × 12.5 mm can and 5 mm lead spacing enable space-conscious through-hole layouts without sacrificing rated voltage.
• Durability for expected service life: Endurance rating of 2000 hours at 85°C provides a measurable reliability baseline for product planning.
• Regulatory compliance: RoHS-compliant materials support regulatory requirements for modern electronic products.
