UHW2A102MHD

The UHW2A102MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a radial-lead, polarized capacitor specified at 1000 µF and 100 V, designed for general-purpose electronic applications that require high capacitance in a compact can-style package.

Key value comes from its combination of high ripple-current capability, low impedance at higher frequencies, and long endurance — rated for 12,000 hours at 105°C — along with RoHS compliance and bulk or bag packaging options for production use.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with tolerance of -20% to +20% at a rated voltage of 100 V.
• High Ripple Current — Low-frequency ripple current of 2.316 A at 120 Hz and high-frequency ripple current of 3.86 A at 10 kHz, supporting designs with significant AC stress.
• Low Impedance — Specified impedance of 76 mΩ and designed for lower impedance at high frequency ranges.
• Endurance — Rated life of 12,000 hours at 105°C under the specified endurance test conditions.
• Thermal Range — Operating temperature range from -40°C to +105°C for wide environmental applicability.
• Leakage & Dissipation — Leakage current specified at 1000 µA and tangent of loss angle (tan δ) of 0.08 measured at 20°C, 120 Hz.
• Form Factor — Miniature radial lead can, size φ18 × 40 mm length, lead spacing 7.5 mm with ±0.5 mm tolerance; radial mounting for through-hole assembly.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for production handling.

Typical Applications

• General-purpose electronic designs — Provides high-capacitance, high-voltage support where a compact radial-lead electrolytic is required.
• High-ripple environments — Suited for general-purpose circuits that require elevated ripple-current capability at both low and high frequencies.
• Long-life systems — Appropriate for designs where endurance at elevated temperature (12,000 hours at 105°C) is a design consideration.

Unique Advantages

• High ripple-current capability: Supports 2.316 A (120 Hz) and 3.86 A (10 kHz) ratings to handle significant AC stress without immediate degradation.
• Low high-frequency impedance: 76 mΩ impedance and design emphasis on reduced impedance at higher frequencies improve performance in AC and switching environments.
• Compact radial package: φ18 × 40 mm can with 7.5 mm lead spacing delivers 1000 µF/100 V capacity in a small footprint for through-hole assemblies.
• Extended endurance: 12,000-hour life at 105°C provides a predictable reliability baseline for long-term designs.
• Wide operating temperature: -40°C to +105°C rating supports use across a broad range of environmental conditions.
• Production-friendly packaging: Available in bulk or bag packing to accommodate board-assembly and inventory workflows.
