UKW1V103MRD

The UKW1V103MRD is a radial‑lead aluminum electrolytic capacitor in Nichicon's UKW series, purpose‑built for audio and AV equipment. It delivers 10,000 µF of capacitance at a 35 V rating in a compact φ22 × 50 mm can, offering high bulk capacitance in a standard radial package.

Designed within an operating temperature range of −40 °C to 85 °C and a rated endurance of 2000 hours at 85 °C, this capacitor is suited to audio designs that require substantial energy storage and robust thermal endurance in a through‑hole form factor.

Key Features

• High Capacitance (Core) — 10,000 µF nominal capacitance provides large bulk energy storage in audio power rails.
• Rated Voltage — 35 V working voltage for mid‑rail audio and AV power systems.
• Loss Characteristics — tan δ (DF) = 0.32 measured at 20 °C, 120 Hz, for predictable dissipation behavior in audio applications.
• Ripple Current Performance — Low‑frequency ripple current 3.7 A (120 Hz) and high‑frequency ripple current 4.255 A (10 kHz), supporting both power‑supply smoothing and higher frequency load modulation.
• Leakage Current — Specified leakage current of 10,500 µA as shipped, enabling designers to account for standby and bias currents.
• Endurance & Temperature Range — Rated lifetime of 2000 hours at 85 °C and an operating range from −40 °C to 85 °C for reliable performance under elevated temperature stress.
• Radial Lead, Through‑Hole Package — φ22 × 50 mm can with 10 mm lead spacing (±0.5 mm) for straightforward PCB mounting and manual assembly workflows.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to match production and prototyping requirements.
• RoHS Compliant — Meets RoHS requirements as stated for environmental compliance.

Typical Applications

• Audio and AV Equipment — Provides 10,000 µF/35 V bulk capacitance in power supply sections and energy storage for amplifiers and AV systems.
• Through‑Hole Power Modules — Radial lead can configuration serves traditional PCB layouts and modules that use axial/radial capacitors.
• High‑Capacity Filtering — Suited where large capacitance and defined ripple handling are required in audio power rails.

Unique Advantages

• Large Energy Reserve: 10,000 µF at 35 V supplies significant bulk capacitance for energy buffering in audio circuits.
• Designed for Audio Quality: UKW series development emphasizes balanced sound characteristics enabled by the series electrolyte formulation.
• Measured Ripple Capability: Specified ripple current values at both low and high frequency (3.7 A at 120 Hz; 4.255 A at 10 kHz) let designers size components for real operating conditions.
• Thermal Endurance: 2000 hours at 85 °C rating provides a measurable lifetime benchmark for elevated temperature designs.
• Standard Through‑Hole Form Factor: φ22 × 50 mm can with 10 mm lead spacing fits common PCB footprints and assembly processes.
• Regulatory Compliance: RoHS compliance supports environmentally constrained product development.
