UFW2A4R7MDD

The UFW2A4R7MDD is a Nichicon UFW-series aluminum electrolytic capacitor in a radial-leaded can, specified at 4.7 µF and 100 V. It is part of the UFW "Standard, For Audio Equipment" family and is provided in a compact φ5 × 11 mm package with 2.0 mm lead spacing.

Designed for audio equipment applications, this capacitor delivers defined endurance and electrical characteristics—including specified tan δ, leakage current, and ripple current performance—across an operating range of −40 °C to +85 °C.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal with a tolerance of −20% to +20% at 120 Hz, 20 °C, enabling predictable capacitance behavior for design margining.
• High Voltage Rating — Rated for 100 V operation to support higher-voltage circuits within audio systems and related electronics.
• Loss Characteristics (tan δ) — Specified tan δ of 0.08 (measured at 20 °C, 120 Hz) for the 100 V rating, useful for assessing dissipation in AC conditions.
• Ripple Current Performance — Low-frequency ripple current of 45 mA at 120 Hz and high-frequency ripple current of 90 mA at 10 kHz, with frequency coefficients defined by the UFW series.
• Leakage Current — Measured leakage current of 14.1 µA, allowing designers to budget quiescent currents and perform leakage checks in circuits.
• Temperature & Endurance — Operates from −40 °C to +85 °C with an endurance rating of 2000 hours at 85 °C per the series specification.
• Physical & Mounting — Radial-lead, polarized aluminum can in a φ5 × 11 mm body with 2.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for manual or automated assembly workflows.

Typical Applications

• Audio equipment — Part of the UFW "Standard, For Audio Equipment" family; suitable for use in audio-related circuits where the series is specified.
• Audio equipment — The 100 V rating and compact φ5 × 11 mm package support higher-voltage and space-constrained designs within audio products.
• Audio equipment — Electrical characteristics such as specified tan δ, leakage current, and ripple current make the part appropriate where those parameters are required to be known and controlled.

Unique Advantages

• Audio-focused series — Belongs to Nichicon’s UFW family, which is specified for audio equipment, providing clear selection alignment for audio designers.
• High-voltage capability — 100 V rating enables use in circuits requiring elevated DC voltages while keeping capacitance in a small form factor.
• Predictable dissipation — Specified tan δ at 120 Hz and 20 °C (0.08) allows engineering assessment of dielectric losses during design and testing.
• Measured leakage spec — The listed leakage current (14.1 µA) gives a verifiable parameter for power budgeting and validation steps.
• Defined ripple performance — Explicit low- and high-frequency ripple current values (45 mA at 120 Hz, 90 mA at 10 kHz) help when specifying filtering and decoupling elements in audio circuits.
• Compact radial package — φ5 × 11 mm radial can with 2.0 mm lead spacing supports compact PCB layouts and through-hole assembly processes.
