UFW2A101MPD

The UFW2A101MPD is an aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment applications. It is a radial-lead, polarized capacitor with a nominal capacitance of 100 µF and a rated voltage of 100 V.

This compact φ10 × 20 mm can offers a low loss tangent (tanδ = 0.08 at 20°C, 120 Hz, 100 V), appreciable ripple-current capability (350 mA at 120 Hz; 525 mA at 10 kHz), and an endurance rating of 2000 hours at 85°C—attributes that support reliable performance in demanding audio circuits and related power stages.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance for predictable energy storage and voltage handling.
• Low Dissipation Factor: tanδ = 0.08 (20°C, 120 Hz, 100 V) for lower internal loss in audio-frequency applications.
• High Ripple Current Capability: Rated for 350 mA at 120 Hz and 525 mA at 10 kHz, supporting both low- and high-frequency ripple demands.
• Endurance: 2000 hours at 85°C with specified post-test limits (capacitance within ±20%, tanδ and leakage current within stated bounds).
• Wide Operating Temperature: −40°C to +85°C operating range for use across typical environmental conditions encountered in audio equipment.
• Radial Lead, Compact Can: φ10 × 20 mm case with 5 mm lead spacing (±0.5 mm) in a radial-lead can package; available in bulk or bag packing for flexible assembly handling.
• Low Leakage: Specified leakage current value of 300 µA, suitable for circuits where low stand-by current is important.

Typical Applications

• Audio Power Supply Filtering: Use in audio amplifier and preamplifier power rails where 100 µF at 100 V and the ripple-current ratings help smooth supply ripple and stabilize rail voltages.
• Decoupling in Audio Circuits: Local decoupling for audio modules and driver stages where low loss (low tanδ) preserves signal fidelity and minimizes thermal stress.
• High-Frequency Ripple Management: Suitable for circuits encountering higher-frequency switching or ripple components, leveraging the 10 kHz ripple-current rating (525 mA).

Unique Advantages

• Audio-Optimized Series: Part of the UFW series specified “for audio equipment,” aligning component selection with audio-focused design requirements.
• Low Loss for Better Sonic Performance: A low tanδ at 120 Hz reduces energy dissipation in the capacitor, which can help maintain cleaner audio reproduction in sensitive stages.
• Compact Footprint: φ10 × 20 mm can size provides a small board footprint for space-constrained audio modules while retaining 100 µF capacitance and 100 V rating.
• Robust Endurance Rating: 2000 hours at 85°C endurance supports sustained operation in continuous-use audio applications.
• Versatile Ripple Handling: Defined ripple-current ratings at both 120 Hz and 10 kHz allow designers to address a range of ripple conditions without overspecifying parts.
• Simple Procurement Options: Available in bulk (no terminal forming) and bag packing to match different production and prototyping workflows.
