UKW1A101MDD

The UKW1A101MDD is a Nichicon UKW-series miniature radial lead aluminum electrolytic capacitor optimized for audio equipment. It delivers 100 µF capacitance at a 10 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing.

Designed for AV and audio applications, this polarized capacitor offers low loss (tanδ = 0.24 at 20°C, 120 Hz), defined ripple-current capability across low and high frequencies, and a rated endurance of 2000 hours at 85°C. Note: this part is currently End Of Life.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20%.
• Compact Radial Lead Package — φ5 × 11 mm can with 2 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for flexible assembly options.
• Audio-Optimized Electrolyte — UKW series formulation developed to realize a harmonious balance of sound quality, targeted for AV equipment.
• Loss and Leakage — Tangent of loss angle (tanδ) up to 0.24 (measured at 20°C, 120 Hz); leakage current specified as 30 µA (per part data).
• Ripple Current Ratings — Low-frequency ripple current 145 mA (120 Hz); high-frequency ripple current 217.5 mA (10 kHz).
• Temperature & Endurance — Operating range −40°C to +85°C with endurance of 2000 hours at 85°C.
• Marking & Compliance — Marked with gold lettering on black sleeve; RoHS compliant.

Typical Applications

• Audio Signal Path — Use in coupling and decoupling stages where compact size and audio-focused electrolyte characteristics help maintain tonal balance.
• AV Equipment Power Rails — Local bypassing and smoothing on low-voltage rails in audio/AV devices, leveraging defined ripple-current ratings.
• Compact Consumer Electronics — Applications requiring a small can-style polarized capacitor for space-constrained PCBs in audio peripherals and portable AV modules.

Unique Advantages

• Audio-focused Electrolyte: Series development emphasizes sound quality, making this part suitable where audible performance is a design priority.
• Small Footprint: φ5 × 11 mm can and 2 mm lead spacing provide a compact solution for tight-layout PCBs without sacrificing capacitance.
• Clear Endurance Specification: 2000 hours at 85°C gives a defined lifetime expectation for thermal-stressed applications.
• Frequency-aware Ripple Performance: Specified ripple-current values at both 120 Hz and 10 kHz help designers size capacitors for real-world audio and switching environments.
• RoHS Compliant: Meets environmental compliance requirements for assembly in current markets.

Why Choose UKW1A101MDD?

UKW1A101MDD is positioned for designers who need a compact, audio-oriented electrolytic capacitor with clear electrical and endurance specifications. Its combination of 100 µF at 10 V, audio-optimized electrolyte characteristics, and measurable ripple-current ratings make it appropriate for local decoupling and signal-coupling roles in AV and consumer audio products.

Although this specific part is listed End Of Life, its documented performance—temperature range, leakage, loss tangent, and 2000-hour endurance—provides the technical traceability engineers require when evaluating replacements or specifying equivalent UKW-series devices from the same family.
