UKW1J101MPD

The UKW1J101MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, specified at 100 µF and 63 V. Designed for audio and AV equipment, it combines a compact φ10 × 12.5 mm can with characteristics targeted at sound-quality-conscious power circuits.

Engineered for reliability across a broad temperature range (–40°C to 85°C) and a rated endurance of 2000 hours at 85°C, this polarized capacitor is suited for smoothing, coupling and decoupling roles in audio power supplies and signal chains.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20% for predictable charge storage in power and audio circuits.
• Audio-Optimized Electrolyte: Part of the UKW series developed to realize a harmonious balance of sound quality through a new electrolyte formulation, making it appropriate for AV and audio equipment.
• Low Dissipation Factor: Specified tanδ of 0.10 measured at 20°C, 120 Hz (for 63 V), supporting efficient performance in audio frequency operation.
• Ripple Current Capability: Rated ripple current of 300 mA at 120 Hz (low frequency) and 450 mA at 10 kHz (high frequency), enabling effective smoothing across common audio power and switching frequencies.
• Leakage Current: Leakage current specified at 189 µA, supporting predictable bias behavior after voltage application.
• Reliability & Lifetime: Endurance rated to 2000 hours at 85°C with specified post-test limits for capacitance change, dissipation factor and leakage current.
• Compact Radial Package: φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole, bulk or bag assembly workflows.
• RoHS Compliant: Meets RoHS requirements for applications requiring restricted-substance compliance.

Typical Applications

• Audio / AV Equipment: Power supply smoothing and signal-path decoupling where sound-quality characteristics and reliable filtering are required.
• Amplifier Power Rails: Bulk and local decoupling on amplifier supply rails to stabilize voltage and support transient currents in audio circuits.
• Consumer Electronics: Use in compact, through-hole designs where a small can and radial leads simplify assembly and placement in chassis-based equipment.

Unique Advantages

• Audio-focused Electrolyte: The UKW series formulation targets a harmonious sound balance, making this capacitor suitable for designs where audio performance is a priority.
• Frequency-aware Ripple Rating: Specified ripple current at both 120 Hz and 10 kHz provides clear, measurable performance for low- and high-frequency filtering needs.
• Compact Footprint: φ10 × 12.5 mm size with 5 mm lead spacing helps save board space while keeping assembly straightforward for through-hole layouts.
• Predictable Endurance: 2000-hour rating at 85°C gives designers known lifetime performance for thermal stress planning and reliability forecasting.
• Conservative Leakage Spec: Defined leakage current supports stable bias conditions in sensitive analog and audio circuits.
• Regulatory Compliance: RoHS compliance supports integration into modern product lines with restricted-substance requirements.
