UFW1C103MHD

The UFW1C103MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, designed specifically for audio equipment applications. It delivers high bulk capacitance (10,000 µF) at a rated voltage of 16 V for power filtering and energy storage in audio power supplies and related circuits.

Key design attributes include a compact φ18 × 35.5 mm can, 7.5 mm lead spacing, a wide operating temperature range of -40°C to 85°C, and a 2000-hour endurance rating at 85°C—providing a balance of capacity, ripple handling, and long-term stability for audio designs.

Key Features

• High Capacitance and Voltage: 10,000 µF rated capacitance at 16 V for large energy storage and smoothing in low-voltage audio power rails.
• Audio-Focused Series: Part of the UFW series specified for audio equipment, making it suitable where audio-grade bulk capacitance is required.
• Ripple Current Capability: Rated ripple current of 2.64 A at 120 Hz (low frequency) and 3.036 A at 10 kHz (high frequency), supporting both mains-frequency and higher-frequency switching ripple environments.
• Dielectric Loss (tan δ): Specified tan δ of 0.38 at 20°C and 120 Hz, allowing designers to account for loss characteristics in audio power stages.
• Leakage and Tolerance: Leakage current specified at 4800 µA and capacitance tolerance of ±20% to meet circuit design margins and startup behaviors.
• Reliability and Endurance: 2000 hours life at 85°C with specified endurance criteria for capacitance, tan δ, and leakage current after test, supporting sustained operation in consumer audio equipment.
• Compact Radial Package: φ18 × 35.5 mm can with 7.5 mm lead spacing in a radial, can package; supplied in bulk/bag packing for assembly processes that use radial components.

Typical Applications

• Audio Power Supplies: Bulk energy storage and smoothing for amplifier rails and power supply decoupling in audio amplifiers and powered speakers.
• Consumer Audio Equipment: Use in receivers, integrated amplifiers, and home audio components where large capacitance and endurance are required.
• Professional Audio Gear: Power filtering in mixers, preamps, and studio equipment that demand stable DC rails over extended operating periods.

Unique Advantages

• Large Bulk Storage: 10,000 µF provides significant energy storage for stable supply rails and improved low-frequency power delivery in audio circuits.
• Designed for Audio Use: Part of Nichicon’s UFW series, explicitly positioned for audio equipment, aligning component choice with application requirements.
• Dual-Frequency Ripple Handling: Rated ripple currents specified for both 120 Hz and 10 kHz facilitate design across linear and switching power topologies.
• Long Endurance at Elevated Temperature: 2000-hour life at 85°C supports durability in warm operating environments common in audio enclosures and rack-mounted equipment.
• Compact Footprint with Standard Lead Spacing: φ18 mm can and 7.5 mm lead spacing simplify PCB layout for radial components while preserving high capacitance density.
