UHW2A121MPD

The UHW2A121MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series designed for high-reliability, general-purpose applications. It provides a 120 µF capacitance at a 100 V rating in a compact φ10 × 25 mm can with a 5 mm lead spacing.

This part combines a long endurance rating at elevated temperature with measurable ripple-current capability and low leakage, making it suitable where compact size, sustained operation up to 105 °C, and reliable performance are required.

Key Features

• Capacitance and Voltage — 120 µF nominal capacitance with a rated voltage of 100 V and a tolerance of −20% to +20%.
• High Ripple Current Capability — Low-frequency ripple current of 648 mA at 120 Hz and high-frequency ripple current of 1.62 A at 10 kHz, supporting applications with significant AC stress.
• Low Loss (tan δ) — Tangent of loss angle (tan δ) specified at 0.08 (measured at 20 °C, 120 Hz), indicating controlled dissipation for the rated voltage and capacitance.
• Low Leakage Current — Specified leakage current of 120 µA, measured under the stated test conditions.
• High Endurance — Rated life of 12,000 hours at 105 °C (when used within rated voltage and ripple conditions), supporting long-term reliability requirements.
• Compact Radial Package — φ10 × 25 mm can with 5 mm lead spacing (lead spacing tolerance ±0.5 mm), radial-lead mounting for through-hole assemblies.
• Wide Operating Temperature — Specified operating range from −40 °C to 105 °C for use across varied ambient conditions.
• Low Impedance — Impedance specified at 280 mΩ, helping to reduce voltage drop under ripple conditions.
• RoHS Compliant — Compliant with RoHS requirements as provided in the product data.

Typical Applications

• General Purpose Electronics — Suited to general-purpose circuit functions that require a polarized aluminum electrolytic capacitor with 120 µF/100 V ratings.
• High-Reliability Systems — Applicable where extended endurance is needed: 12,000 hours at 105 °C supports long-term operation under rated conditions.
• Compact or Space-Constrained Designs — The miniature φ10 × 25 mm can size and radial-lead package simplify placement where board area or profile is limited.

Unique Advantages

• Measurable High Ripple Handling: Specified ripple currents of 648 mA (120 Hz) and 1.62 A (10 kHz) provide clear guidance for AC stress budgeting in designs.
• Defined Endurance at Elevated Temperature: 12,000 hours life at 105 °C gives predictable longevity for thermal-stressed applications.
• Compact Footprint: φ10 × 25 mm package with 5 mm lead spacing delivers necessary capacitance while minimizing board space.
• Low Leakage and Controlled Losses: 120 µA leakage current and tan δ of 0.08 (20 °C, 120 Hz) help maintain efficiency and reduce standby dissipation.
• Wide Operating Range: −40 °C to 105 °C operating temperature range supports use across varied environments.
• Through-Hole Mounting Simplicity: Radial-lead form factor and standard lead spacing ease prototyping and assembly for mixed-technology boards.
