UHW2A101MPD

The UHW2A101MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can from Nichicon’s UHW series. It delivers 100 µF capacitance at a 100 V rating with a compact φ10 × 20 mm package and 5 mm lead spacing, suited for space-constrained designs that require high ripple handling.

Designed for general-purpose electronic equipment, this component combines low loss (tanδ 0.08 at 20°C, 120 Hz), defined impedance (340 mΩ), and long endurance (12,000 hours at 105°C) to support robust power smoothing and decoupling in demanding environments.

Key Features

• Rated Performance — 100 µF capacitance with ±20% tolerance and 100 V rated voltage for high-voltage general-purpose circuits.
• Miniature Radial Package — φ10 × 20 mm can with 5 mm lead spacing and radial lead mounting for through-hole assemblies and prototyping.
• High Ripple Current Capability — Low-frequency ripple current 572 mA (120 Hz) and high-frequency ripple current 1.43 A (10 kHz) to handle significant AC stress in power applications.
• Low Loss — tanδ (DF) of 0.08 measured at 20°C, 120 Hz, supporting efficient energy handling and lower heat generation.
• Long Endurance — Rated for 12,000 hours at 105°C, providing extended operational life in elevated-temperature installations.
• Leakage and Impedance — Leakage current specified at 100 µA and impedance characterized at 340 mΩ for predictable performance in DC bias applications.
• Regulatory Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Power Supply Filtering — Smoothing and bulk energy storage in general-purpose power supplies where 100 V rating and high ripple capability are required.
• DC Link and Decoupling — Decoupling and local energy buffering for converters and power stages that demand low impedance at higher frequencies.
• Industrial and Instrumentation Electronics — Reliable energy storage for control and measurement equipment operating across −40°C to 105°C.

Unique Advantages

• High-Voltage Capability: 100 V rating enables use in higher-voltage bulk and intermediate circuits without series stacking.
• Compact Footprint: φ10 × 20 mm can minimizes board area while retaining substantial capacitance for space-constrained designs.
• High-Frequency Performance: Measured high-frequency ripple current of 1.43 A at 10 kHz and low tanδ support efficient operation in switching environments.
• Extended High-Temperature Lifetime: 12,000 hours at 105°C reduces maintenance and replacement frequency in hot operating conditions.
• Predictable Leakage and Impedance: Specified leakage current (100 µA) and impedance (340 mΩ) help simplify thermal and reliability calculations.
• RoHS Compliant Packaging Options: Available in bulk or bag packing to match production and inventory handling preferences.
