UKW1V153MRD

The UKW1V153MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, designed for audio and AV equipment requiring large bulk capacitance. It pairs a 15,000 µF capacitance with a 35 V rating in a compact φ25×50 mm aluminum-can package optimized for power supply smoothing and energy storage in audio circuits.

Engineered around Nichicon’s UKW series electrolyte formulation, this part targets applications where audible performance and sustained ripple handling are important, while operating across a wide temperature range from −40°C to 85°C.

Key Features

• High Capacitance: 15,000 µF bulk capacitance for large energy storage and supply decoupling in audio power stages.
• Rated Voltage: 35 V working voltage suitable for many audio and AV power-rail designs.
• Capacitance Tolerance: −20% to +20% at 120 Hz, 20°C, allowing predictable bulk performance.
• Loss Tangent (tan δ): Specified tan δ (DF) of 0.42 measured at 20°C, 120 Hz, supporting characterisation of ESR-related behavior.
• Ripple Current Capability: Low-frequency ripple handling of 4.3 A (120 Hz) and high-frequency ripple handling of 4.945 A (10 kHz), enabling reliable filtering under dynamic load conditions.
• Leakage Current: Specified leakage current of 15,750 µA, useful for system-level bias and standby calculations.
• Endurance: Rated life of 2,000 hours at 85°C with defined post-test limits for capacitance, tan δ, and leakage current.
• Temperature Range: Operates from −40°C to 85°C to support a broad range of environmental conditions.
• Package and Mounting: Radial lead, aluminum can construction sized φ25×50 mm with 12.5 mm lead spacing; available in bulk or bag packing.
• RoHS Compliant: Meets RoHS requirements as stated for the UKW series.

Typical Applications

• Audio Amplifiers: Bulk supply filtering and energy reservoir for power amplifier stages where large capacitance and ripple handling reduce audible supply modulation.
• AV Equipment Power Supplies: Bulk smoothing and decoupling in AV and consumer electronics power rails that operate up to 35 V and need stable performance across −40°C to 85°C.
• Power Filtering in Preamp and Signal Chains: Energy storage and low-frequency decoupling to support steady biasing and reduced ripple in audio front-ends.

Unique Advantages

• Large Bulk Energy Storage: 15,000 µF provides significant stored charge for stabilizing supply rails and supporting transient demands.
• Designed for Audio Use: Part of the UKW series with electrolyte development intended to achieve a harmonious balance of sound quality for AV applications.
• Robust Ripple Handling: Specified ripple currents at both low and high frequencies (4.3 A at 120 Hz, 4.945 A at 10 kHz) enable effective filtering across audio-relevant bandwidths.
• Wide Operating Temperature: −40°C to 85°C rating and 2,000-hour endurance at 85°C support reliable operation in varied environments.
• Radial-Lead Can Format: φ25×50 mm aluminum can with 12.5 mm lead spacing for through-hole assemblies where high capacitance and simple mounting are required.
• Regulatory Compliance: RoHS-compliant construction for environmentally conscious designs.
