UFW1H3R3MDD

The UFW1H3R3MDD is a Nichicon UFW series aluminum electrolytic capacitor in a radial-lead can, rated at 3.3 µF and 50 V. Designed for audio equipment, this polarized through-hole capacitor delivers compact size and targeted electrical performance for signal-path and decoupling applications.

Key characteristics include low dissipation (tan δ = 0.12 at 20°C, 120 Hz), defined ripple current capability across low and high frequencies, and a 2000-hour endurance rating at 85°C, making it suitable for compact audio circuits that require stable performance over time.

Key Features

• Electrical Rating — 3.3 µF nominal capacitance at a 50 V rated voltage with ±20% tolerance for predictable circuit behavior.
• Low Loss — tan δ = 0.12 measured at 20°C and 120 Hz, supporting low dissipation in audio signal paths.
• Leakage Current — 4.95 µA specified leakage current, aiding in low-noise applications.
• Ripple Current Capability — 35 mA at 120 Hz (low frequency) and 70 mA at 10 kHz (high frequency) to support both power filtering and higher-frequency decoupling needs.
• Reliability & Endurance — Rated for 2000 hours at 85°C, with performance limits defined for capacitance change, tan δ, and leakage after endurance testing.
• Mechanical & Mounting — Radial lead, can-style package with φ5 × 11 mm dimensions and 2 mm lead spacing for compact through-hole PCB layouts.
• Operating Range — Specified to operate from −40°C to +85°C, suitable for typical consumer and professional audio environments.

Typical Applications

• Audio Equipment — Suited for signal-path and power decoupling in audio amplifiers, preamplifiers, and related audio modules.
• Analog Filtering — Use in small-footprint analog filter networks where low dissipation and defined capacitance tolerance are important.
• Compact Through-Hole Designs — Through-hole radial form factor and small φ5×11 mm size make it appropriate for dense PCBs and module-level assemblies used in audio products.

Unique Advantages

• Audio-oriented electrical profile — Low tan δ and controlled leakage current support cleaner audio signal handling and lower distortion in signal paths.
• Frequency-capable ripple performance — Specified ripple current at both 120 Hz and 10 kHz enables reliable filtering across audio and higher-frequency decoupling needs.
• Compact, board-friendly package — φ5×11 mm can and 2 mm lead spacing reduce PCB real estate while maintaining through-hole mounting robustness.
• Defined endurance specification — 2000 hours at 85°C with post-test limits for capacitance, tan δ, and leakage provides clear expectations for lifetime performance.
• Polarized design for conventional audio circuits — Standard electrolytic polarity simplifies integration into typical audio power and coupling circuits.
