UFW1V103MRD

The UFW1V103MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, specified for audio equipment. It delivers high bulk capacitance in a polarized, can-style radial package suited to through-hole assemblies.

Key attributes include 10,000 µF capacitance at 35 V, rated endurance of 2000 hours at 85°C, and defined ripple performance at both low and high frequencies—making it applicable where large energy storage and sustained ripple handling are required in audio designs.

Key Features

• High Capacitance & Voltage: 10,000 µF nominal capacitance rated at 35 V for substantial bulk energy storage in power rails.
• Tolerance & Polarization: ±20% capacitance tolerance; polarized design for DC applications.
• Loss Tangent (tan δ): 0.32 tanδ measured at 20°C and 120 Hz, reflecting the series' specified dissipation characteristics for large-value capacitors.
• Ripple Current Capability: 3,700 mA at 120 Hz (low frequency) and 4,255 mA at 10 kHz (high frequency), supporting sustained AC ripple on DC rails.
• Leakage Current: Specified leakage current of 10,500 µA after rated voltage application.
• Endurance: 2,000 hours at 85°C with rated voltage applied; endurance criteria specify capacitance change within ±20% and limits on tan δ and leakage current after test.
• Temperature Range: Operating from −40°C to +85°C for deployment across common environmental conditions in audio electronics.
• Package & Mechanical: Radial can package, size φ22 × 50 mm, lead spacing 10 mm ±0.5 mm, supplied in bulk (no terminal forming) / bag packing.
• Lifecycle Status: Product is marked End Of Life.

Typical Applications

• Audio Equipment — Intended for use in audio designs where large bulk capacitance and defined ripple handling at both low and high frequencies are required.
• Power Supply Smoothing — Applicable where 10,000 µF at 35 V is needed to stabilize DC rails in audio power stages.
• Energy Reservoirs — Suitable for circuits that require sustained energy storage and ripple filtering within the specified temperature and endurance limits.

Unique Advantages

• Substantial Bulk Storage: 10,000 µF capacitance provides significant stored charge capacity for smoothing and transient support.
• Defined Ripple Performance: Rated ripple currents of 3.7 A (120 Hz) and 4.255 A (10 kHz) enable designers to specify AC endurance for both low- and high-frequency ripple conditions.
• Endurance Characterization: 2,000 hours at 85°C with post-test limits for capacitance, tan δ and leakage current gives a measurable reliability baseline for design margining.
• Through-Hole, Serviceable Form Factor: Radial lead, can package (φ22 × 50 mm) with 10 mm lead spacing supports traditional PCB layouts and manual assembly or rework.
• Audio-Focused Series: Part of Nichicon’s UFW series specified for audio equipment, aligning the component’s electrical profile with audio application requirements.
• Packaging Options: Available in bulk or bag packing to suit production or prototype workflows.
