UKW1E103MRD

The UKW1E103MRD 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 25 V in a compact φ20 × 40 mm can, providing energy storage and smoothing for power rails and audio circuits.

Designed with Nichicon’s UKW-series electrolyte formulation to support a harmonious balance of sound quality, this component targets designers of audio amplifiers, AV systems and power supply subsystems that require large capacitance, measurable ripple-handling and defined endurance characteristics.

Key Features

• Capacitance & tolerance — 10,000 µF nominal with ±20% tolerance (120 Hz, 20°C), suitable for high-capacity reservoir and smoothing applications.
• Rated voltage — 25 V DC rating for mid-voltage power rails.
• Loss characteristics (tan δ) — tanδ = 0.34 measured at 20°C, 120 Hz (accounts for capacitance scaling above 1,000 µF).
• Ripple current capability — 3.00 A at 120 Hz (low frequency) and 3.45 A at 10 kHz (high frequency), enabling effective AC ripple handling in supply and audio circuits.
• Leakage current — Specified at 7,500 µA (product data); designed to meet electrolytic leakage behavior parameters under rated conditions.
• Reliability & lifetime — Endurance rated for 2,000 hours at 85°C with specified limits on capacitance change, tanδ and leakage current after test.
• Operating temperature — −40°C to +85°C to accommodate a wide range of ambient conditions for AV and audio equipment.
• Mechanical & mounting — Radial lead, φ20 × 40 mm can with 10 mm lead spacing (±0.5 mm); packaging available in bulk (no terminal forming) or bag packing.
• Environmental compliance — RoHS compliant.
• Lifecycle status — End Of Life.

Typical Applications

• Audio power supplies — Bulk energy storage and smoothing for amplifier power rails and power-supply filter stages.
• AV equipment — Decoupling and reservoir capacitance in receivers, home-theater components and other AV subsystems where large capacitance supports stable operation.
• Amplifier power stages — Supply stabilization for analogue amplification stages that benefit from high capacitance and controlled loss characteristics.
• Filter and reservoir circuits — Low-frequency smoothing and energy buffering in power-management and signal-conditioning circuits.

Unique Advantages

• High bulk energy storage: 10,000 µF at 25 V provides significant reservoir capacitance for smoothing and transient support in power rails.
• Measured audio-oriented formulation: Part of Nichicon’s UKW series designed to realize a harmonious balance of sound quality through its electrolyte development.
• Defined ripple performance: Rated ripple currents of 3.00 A (120 Hz) and 3.45 A (10 kHz) enable reliable ripple handling across low and high frequency ranges.
• Wide operating temperature and proven endurance: −40°C to +85°C range with 2,000 hours endurance at 85°C for predictable behavior in long-running AV installations.
• Through-hole radial package: Radial lead can and 10 mm lead spacing simplify through-hole assembly, replacement and mechanical retention in chassis-mounted designs.
• Regulatory compliance: RoHS-compliant construction supports environmentally conscious product builds.
