UKW1A103MHD

The UKW1A103MHD is a Nichicon UKW series miniature aluminum electrolytic capacitor designed for audio and AV equipment. It is a polarized radial-lead capacitor providing 10,000 µF capacitance at a 10 V rating in a compact φ16 × 35.5 mm can.

This part delivers large bulk capacitance, measurable ripple-handling capability, and a 2000-hour endurance rating at 85°C—making it suitable for high-capacitance needs in audio power and AV circuitry where long-term stability and RoHS compliance are required.

Key Features

• Capacitance & Voltage — 10,000 µF capacitance at a 10 V rated voltage with capacitance tolerance of -20% to +20%.
• Low-frequency and high-frequency ripple handling — Rated low-frequency ripple current 2.5 A (120 Hz) and high-frequency ripple current 2.875 A (10 kHz), supporting power-rail smoothing in demanding audio applications.
• Electrical loss and leakage — Tangent of loss angle (tan δ) 0.42 measured at 20°C, 120 Hz, and leakage current specified at 3000 µA.
• Endurance and temperature range — Endurance of 2000 hours at 85°C; operating temperature range from -40°C to +85°C.
• Package and mounting — Radial lead, polarized aluminum can; physical dimensions φ16 × 35.5 mm with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting.
• Packaging options — Available in bulk (no terminal forming) or bag packing for production or prototyping workflows.
• Compliance — RoHS compliant.

Typical Applications

• Audio equipment — Bulk energy storage and smoothing on power rails for amplifiers and audio signal chains where large capacitance is required.
• AV systems — Power filtering and reservoir capacitance in consumer and professional AV gear consistent with the UKW series targeting AV performance.
• High-capacitance through-hole designs — Use in boards that require a compact radial-lead aluminum electrolytic with substantial capacitance and ripple capability.

Unique Advantages

• Substantial bulk capacitance: 10,000 µF at 10 V provides large energy storage in a compact φ16 × 35.5 mm can, reducing the need for multiple smaller capacitors.
• Ripple capability across frequencies: Specified ripple currents at 120 Hz and 10 kHz support both low- and high-frequency power disturbances common in audio and AV power rails.
• Long endurance at elevated temperature: 2000 hours at 85°C gives predictable life characteristics for sustained operation in warmer equipment enclosures.
• Radial-lead form factor: Through-hole mounting with 7.5 mm lead spacing simplifies retrofit or PCB-level replacement in existing designs.
• RoHS compliant: Meets environmental directive requirements for electronic assemblies.
