UKW1A153MHD

The UKW1A153MHD is a miniature aluminum electrolytic capacitor in Nichicon's UKW series, designed specifically for audio and AV equipment. It is a polarized, radial‑lead can delivering high capacitance (15,000 µF) at a 10 V rating in a compact φ18 × 35.5 mm package.

This part offers high ripple current capability and a robust endurance rating, making it suitable for reservoir and smoothing applications where sustained performance at elevated temperatures is required.

Key Features

• Core Capacitance — 15,000 µF nominal capacitance with ±20% tolerance, providing large bulk energy storage in a compact radial can.
• Rated Voltage & Polarization — Rated for 10 V DC and is polarized for standard electrolytic applications.
• Loss Angle (tan δ) — tanδ = 0.52 measured at 20°C, 120 Hz, suitable for evaluating AC loss in audio power circuits.
• Ripple Current Performance — Low‑frequency ripple current 2.72 A (120 Hz) and high‑frequency ripple current 3.128 A (10 kHz), supporting demanding smoothing and decoupling in power rails.
• Leakage Current — Specified leakage current of 4500 µA as a characterization metric for bias conditions.
• Temperature & Endurance — Rated operating temperature −40°C to +85°C with an endurance of 2000 hours at 85°C.
• Mechanical & Mounting — Radial lead, can package with case size φ18 × 35.5 mm and lead spacing 7.5 mm (±0.5 mm) for through‑hole PCB mounting.
• Packaging & Availability — Available in bulk (no terminal forming) and bag packing; status: mass production.
• Regulatory — RoHS compliant.

Typical Applications

• Audio Equipment (AV systems) — Bulk energy storage and reservoir smoothing for amplifiers and AV power supplies where high capacitance at low voltage is required.
• Power Supply Filtering — Smoothing and decoupling on low‑voltage rails in consumer and professional audio electronics.
• Signal‑Sensitive Electronics — Energy buffering in circuits where stable supply under varying load is important for maintained audio performance.

Unique Advantages

• High Capacitance Density: 15,000 µF in a φ18 × 35.5 mm radial can enables significant bulk storage without a large board footprint.
• Defined Ripple Capability: Specified ripple currents at both 120 Hz and 10 kHz allow designers to assess performance across typical audio frequency ranges.
• Temperature and Endurance Specified: −40°C to +85°C operating range with 2000 hours endurance at 85°C provides predictable life characteristics for thermal design and reliability planning.
• Series‑Level Audio Focus: Part of Nichicon’s UKW family developed for AV/audio use, aligning materials and performance toward audio applications.
• RoHS Compliance & Production Availability: RoHS compliant and in mass production, simplifying procurement and compliance for product builds.
