UFW1H100MDD

The UFW1H100MDD is a Nichicon UFW-series aluminum electrolytic capacitor in a radial-lead can optimized for audio applications. It delivers 10 µF capacitance at a 50 V rating in a compact φ5 × 11 mm package with 2 mm lead spacing.

Key electrical characteristics include a low dissipation factor (tanδ = 0.12 at 20°C, 120 Hz), controlled leakage (15 µA), and specified ripple current handling (65 mA at 120 Hz, 130 mA at 10 kHz). The part is rated for operation from −40°C to 85°C and has a 2000 h endurance at 85°C. Note: this part is listed with an End Of Life status.

Key Features

• Capacitance & Voltage: 10 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for DC decoupling and bias applications in audio circuits.
• Low Loss for Audio: tanδ = 0.12 (measured at 20°C, 120 Hz) to minimize signal loss and preserve audio fidelity in coupling and filter stages.
• Ripple Current Capability: Rated ripple current of 65 mA at 120 Hz and 130 mA at 10 kHz, supporting both low- and high-frequency filtering requirements.
• Low Leakage: Specified leakage current of 15 µA to reduce DC bias errors in sensitive circuits.
• Thermal Endurance: 2000 hours rated life at 85°C, with an operating temperature range from −40°C to 85°C for stable performance across typical audio environments.
• Compact Radial Package: φ5 × 11 mm can with 2 mm lead spacing and radial leads for through‑hole assembly; supplied bulk in bag packing.

Typical Applications

• Audio Equipment: Coupling and decoupling in amplifiers and preamplifiers where low dissipation and controlled leakage preserve signal integrity.
• Power Supply Filtering for Audio Circuits: Local smoothing and noise suppression on audio power rails, leveraging specified ripple current ratings for both low and high frequency components.
• Signal Path Conditioning: Use in tone control, filter, and timing networks where a stable capacitance and low tanδ contribute to predictable audio response.

Unique Advantages

• Audio-oriented electrical profile: The combination of low tanδ and low leakage supports clean signal handling in audio signal chains.
• Balanced ripple handling: Specified ripple current at both 120 Hz and 10 kHz enables use in supply filters that see a range of ripple frequencies.
• Small footprint, through‑hole convenience: φ5 × 11 mm radial-can package with 2 mm lead spacing provides a compact solution for legacy or mixed-technology boards.
• Durability at elevated temperature: 2000-hour rated life at 85°C offers predictable long-term behavior in temperature-stressed environments.
• Manufacturer pedigree: Part of Nichicon’s UFW series designed for audio equipment applications, carrying consistent series-level specifications for designers.
