UFW1V153MRD

The UFW1V153MRD is a high-capacitance, radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, designed for audio equipment. It provides bulk energy storage and support for power delivery in through-hole designs.

Key attributes include 15,000 µF capacitance at 35 V, high ripple-current capability at both low and high frequencies, and an endurance rating defined at elevated temperature for reliable performance in audio power circuits.

Key Features

• Capacitance & Tolerance — 15,000 µF (15 mF) nominal capacitance with tolerance of −20% to +20% for predictable bulk energy storage.
• Rated Voltage — 35 V continuous voltage rating suitable for many audio power supply rails.
• High Ripple Current — Low-frequency ripple current 4.3 A at 120 Hz and high-frequency ripple current 4.945 A at 10 kHz to support demanding audio amplifier loads.
• Loss Tangent (tan δ) — tanδ (DF) specified as 0.42 when measured at 20°C, 120 Hz, enabling designers to account for dissipation in thermal and stability calculations.
• Leakage Current — Specified leakage current of 15,750 µA for initial design margining.
• Endurance & Temperature — Rated for 2,000 hours at 85°C with an operating temperature range of −40°C to 85°C for sustained performance in temperature-variable environments.
• Package & Mounting — Radial-lead, can-style package sized φ25 × 50 mm with 12.5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB layout.
• Polarized — Designed as a polarized electrolytic component for DC power applications.
• Packaging Options — Available in Bulk (No Terminal Forming) or Bag Packing to accommodate different assembly workflows.
• Manufacturer & Series — Produced by Nichicon as part of the UFW series, specified for audio equipment.
• Status — End Of Life.

Typical Applications

• Audio Equipment — Bulk energy storage and power smoothing in consumer and professional audio systems where large capacitance is required.
• Audio Amplifiers — Support for amplifier power rails to reduce low-frequency ripple and sustain transient current demands.
• Audio Power Supplies — Filtering and decoupling in supply sections of audio electronics to stabilize voltage under load.

Unique Advantages

• Substantial energy storage: 15,000 µF provides significant reservoir capacity for audio power stages and long-duration smoothing.
• High ripple handling: Specified ripple currents at both 120 Hz and 10 kHz allow designers to account for low- and high-frequency stress in power circuits.
• Temperature-endurance specification: 2,000 hours at 85°C and a −40°C to 85°C operating window support robust performance in temperature-variable installations.
• Through-hole robustness: Radial leaded can and clearly specified lead spacing make this part suitable for manual assembly and legacy board designs.
• Design transparency: Explicit specifications for tanδ and leakage current enable precise thermal and reliability margining during development.
• Flexible handling: Bulk and bag packaging options support prototyping and lower-volume production workflows.

Why Choose UFW1V153MRD?

The UFW1V153MRD is positioned for designers of audio equipment who require substantial bulk capacitance, clear electrical characterization, and through-hole mounting for robust mechanical retention. Its combination of high capacitance, defined ripple-current ratings at multiple frequencies, and an endurance rating at elevated temperature make it suitable for power-smoothing roles in audio power supplies and amplifiers.

Manufactured by Nichicon as part of the UFW series, this component provides measurable design inputs—capacitance, tanδ, leakage current, ripple current, size, and endurance—so engineers can reliably integrate it into audio-focused power subsystems. Status: End Of Life.
