UHW2A561MHD

The UHW2A561MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series, supplied in a radial-lead can. It delivers 560 µF capacitance at a 100 V rating and is designed for general-purpose power applications requiring high ripple handling and stable performance across a wide temperature range.

Key value propositions include low impedance at higher frequencies, high ripple-current capability, and long endurance (12,000 hours at 105°C), making this part suitable for demanding power-filtering roles in electronic systems.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a 100 V rated voltage and a tolerance of −20% to +20% for predictable energy storage on power rails.
• High ripple-current capability: Specified ripple currents of 1.32 A at 120 Hz and 2.64 A at 10 kHz support sustained AC loading and decoupling in switching power applications.
• Low impedance: Rated impedance of 95 mΩ helps reduce voltage ripple and improve transient response in high-frequency environments.
• Thermal and lifetime performance: Operating temperature range of −40°C to 105°C with endurance rated to 12,000 hours at 105°C for long-term reliability under elevated temperatures.
• Frequency performance: Lower impedance at high frequency and a tan δ (DF) of 0.08 (measured at 20°C, 120 Hz, 100 V) for consistent loss characteristics.
• Package and mounting: Radial lead can, size φ16 × 30.5 mm, lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing for board-level assembly.
• Leakage current control: Specified leakage current of 560 µA to assist in predictable standby and no-load behavior.
• Environmental compliance: RoHS-compliant construction.

Typical Applications

• Power supply smoothing and filtering: Bulk capacitance (560 µF) and 100 V rating provide energy storage and ripple reduction on DC power rails.
• Switch-mode power supplies and DC–DC converters: High ripple-current capability (1.32 A at 120 Hz, 2.64 A at 10 kHz) and low impedance support high-frequency switching environments.
• Industrial and general-purpose electronics: Wide operating temperature range (−40°C to 105°C) and 12,000-hour endurance at 105°C suit sustained operation in industrial power modules and control systems.

Unique Advantages

• Miniature footprint with substantial capacitance: φ16 × 30.5 mm package delivers 560 µF in a compact radial-lead can for space-constrained board layouts.
• High-frequency performance: Lower impedance at high frequencies and specified high-frequency ripple current capability improve transient suppression and filtering in switching circuits.
• Long-term reliability at elevated temperature: Rated for 12,000 hours at 105°C, enabling predictable lifetime behavior in hot operating environments.
• Predictable electrical characteristics: Explicit specs for impedance (95 mΩ), tan δ (0.08 at 120 Hz, 20°C), and leakage current (560 µA) aid in detailed design and margin analysis.
• Polarized radial-lead format: Through-hole radial leads and standard lead spacing (7.5 mm ±0.5 mm) simplify assembly and mechanical retention for wave or hand soldered boards and prototyping.
• Regulatory compliance: RoHS status provided for electronics manufacturing compliance.
