UFW1H4R7MDD

The UFW1H4R7MDD is a Nichicon UFW series aluminum electrolytic capacitor in a compact radial-lead can. It delivers 4.7 µF capacitance at a 50 V rating and is designed for audio and related analog applications where small size and controlled loss are important.

Key attributes include a 50 V rating, low loss (tan δ 0.12 at 20 °C, 120 Hz), specified ripple current capability at low and high frequency, and a broad operating range from −40 °C to 85 °C with a 2000‑hour endurance at 85 °C.

Key Features

• Capacitance & Tolerance — 4.7 µF capacitance with ±20% tolerance, suitable for decoupling and coupling in audio circuits.
• Voltage Rating — Rated at 50 V to support mid‑range supply rails and signal-blocking applications.
• Low Loss Characteristics — tan δ (DF) 0.12 measured at 20 °C, 120 Hz, delivering predictable dissipation for audio paths and analog filtering.
• Ripple Current Capability — Low‑frequency ripple current 40 mA (120 Hz) and high‑frequency ripple current 80 mA (10 kHz), enabling use in supply filtering and signal chain decoupling across frequencies.
• Leakage Current — Specified leakage current of 7.05 µA; series leakage measurement definitions are provided in the UFW datasheet for reference.
• Mechanical & Mounting — Radial lead, can package with φ5 × 11 mm body size and 2.0 mm lead spacing (±0.5 mm), for through‑hole assembly and compact board placement.
• Temperature & Endurance — Operating range −40 °C to 85 °C with endurance of 2000 hours at 85 °C, suitable for long‑life consumer and professional audio equipment.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to match assembly and inventory workflows.

Typical Applications

• Audio signal coupling — Use for coupling stages and blocking DC in amplifier and preamplifier circuits where low dissipation is required.
• Power-supply decoupling — Local decoupling on mid‑voltage rails in audio electronics and small consumer devices.
• Analog filtering — Small form‑factor RC or LC networks where a 4.7 µF capacitor and 50 V rating meet design requirements.

Unique Advantages

• Compact radial can — φ5×11 mm body enables space‑constrained PCB layouts without sacrificing rated voltage.
• Defined loss performance — Specified tan δ at 20 °C/120 Hz provides predictable behavior for audio and analog signal paths.
• Frequency-aware ripple rating — Specified ripple current values at 120 Hz and 10 kHz help designers size caps for both low‑ and high‑frequency ripple environments.
• Robust temperature endurance — 2000 hours at 85 °C endurance supports longer life in consumer and professional audio equipment.
• Through-hole convenience — Radial lead format and standard 2.0 mm lead spacing simplify prototyping and repairable designs.
