UKW1C103MHD

The UKW1C103MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, optimized for audio and AV equipment. It delivers high bulk capacitance (10,000 µF) at a 16 V rating in a compact φ18 × 35.5 mm can for applications that require large energy storage and stable performance across a wide temperature range.

Designed for long-term operation, this part offers specified endurance of 2000 hours at 85 °C and RoHS compliance, making it suitable for engineered audio designs where predictable lifetime and measurable ripple handling matter.

Key Features

• High Capacitance — 10,000 µF nominal capacitance provides substantial bulk energy storage for audio/AV circuits.
• Rated Voltage — 16 V working voltage suitable for common low-voltage audio power rails.
• Loss Angle (tan δ) — tanδ = 0.38 measured at 20 °C, 120 Hz, reflecting the part’s specified dissipation characteristics for its capacitance and voltage class.
• Ripple Current Handling — Low-frequency ripple current of 2.64 A (120 Hz) and high-frequency ripple current of 3.036 A (10 kHz) for sustained AC loading scenarios.
• Leakage Current — Leakage current specified at 4800 µA for the part, allowing designers to account for standby and quiescent currents.
• Temperature and Endurance — Operating range −40 °C to +85 °C with endurance of 2000 hours at 85 °C per the product specification.
• Package and Mounting — Radial-lead aluminum can (φ18 × 35.5 mm) with 7.5 mm lead spacing and available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.

Typical Applications

• Audio Equipment — Suited for audio and AV systems requiring large capacitance for signal path/energy support and consistent performance across temperature extremes.
• AV Systems — Appropriate for consumer and professional AV equipment in need of bulk capacitance in power supply and filtering stages.
• Audio Power Stages — Provides measurable ripple-handling capacity for power-stage decoupling and energy buffering in amplifier designs.

Unique Advantages

• Substantial Bulk Energy Storage: 10,000 µF nominal capacitance delivers large charge capacity for smoothing and buffering in audio circuits.
• Measured Ripple Performance: Rated ripple currents of 2.64 A (120 Hz) and 3.036 A (10 kHz) let designers size capacitors against expected AC stress with quantified values.
• Endurance at Elevated Temperature: Specified for 2000 hours at 85 °C, enabling predictable lifetime planning for deployed products.
• Audio-Focused Electrolyte Development: Part of Nichicon’s UKW series developed for audio equipment, reflecting series-level emphasis on sound-oriented performance characteristics.
• Compact Radial Package: φ18 × 35.5 mm aluminum can with 7.5 mm lead spacing provides a compact footprint for through-hole board layouts and manual or automated radial insertion.
• Regulatory Compliance: RoHS status documented for use in designs where restricted-substance compliance is required.

Why Choose UKW1C103MHD?

UKW1C103MHD positions itself as a high-capacitance, audio-oriented aluminum electrolytic capacitor that balances large energy storage with specified ripple handling and defined endurance. Its radial can package and 7.5 mm lead spacing make it straightforward to integrate into through-hole audio and AV designs where measurable performance and predictable lifetime are required.

This part is well suited for engineers designing audio power supplies, amplifier stages, and AV equipment who need explicit specifications—capacitance, voltage, ripple currents, leakage, temperature range, and endurance—to guide BOM selection and reliability planning. RoHS compliance and series-level audio focus add to its long-term design value.
