UKW1C153MRD

The UKW1C153MRD is a high-capacitance aluminum electrolytic capacitor in a radial-lead can designed for audio and AV equipment. It delivers 15,000 µF at 16 V with a compact φ20×40 mm package and is part of Nichicon’s UKW series developed for audio applications using a new electrolyte formulation to support sound-quality-focused designs.

Engineered for power smoothing and energy reservoir roles in audio power supplies, the device combines large capacitance, robust ripple handling and rated endurance to support sustained operation at elevated temperatures.

Key Features

• High Capacitance — 15,000 µF nominal capacitance with ±20% tolerance, providing substantial bulk energy storage for power supply smoothing and reservoir functions.
• Rated Voltage — 16 V working voltage suitable for a range of low-voltage audio and AV power rails.
• Ripple Current Handling — Low-frequency ripple current 3.4 A (120 Hz) and high-frequency ripple current 3.91 A (10 kHz), supporting continuous ripple filtering in power stages.
• Endurance — 2000 hours rated life at 85 °C, with specified limits on capacitance change, tan δ and leakage after the endurance test.
• Broad Temperature Range — Operating from −40 °C to +85 °C for stable performance across typical AV operating environments.
• Radial Lead Can Package — φ20×40 mm aluminum can with 10 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Audio and AV Power Supplies — Provides bulk energy storage and smoothing for amplifier and AV system power rails, leveraging high capacitance and ripple current capability.
• Amplifier Reservoir Capacitor — Stabilizes supply rails in power amplifier stages where large charge reservoirs and reliable endurance are required.
• Decoupling for High-Current Circuits — Used where sustained ripple currents need to be absorbed at low and high frequencies in audio electronics.

Unique Advantages

• Substantial Bulk Storage: 15,000 µF capacity reduces output ripple and extends hold-up for audio power stages, minimizing sag under load.
• Dual-Frequency Ripple Performance: Rated ripple currents at both 120 Hz and 10 kHz address low-frequency smoothing and higher-frequency switching ripple, simplifying filter design.
• Proven Endurance: 2000 hours at 85 °C with defined limits on capacitance change and leakage supports predictable longevity in thermal-stressed environments.
• Audio-Optimized Series: Part of Nichicon’s UKW series developed for audio/AV equipment, incorporating electrolyte choices aimed at balanced sound characteristics.
• Through-Hole Robustness: Radial lead mounting and a standard can form factor facilitate easy integration into boards requiring mechanical stability and serviceability.
• Regulatory Compliance: RoHS compliance provides environmental conformity for equipment manufacturing.
