UPW2E101MHD

The UPW2E101MHD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon's UPW series, designed for low‑impedance, high‑reliability power applications. This polarized, can‑style capacitor provides 100 µF capacitance at a 250 V rating with through‑hole radial mounting and is optimized for switching power supplies and robust power rails.

Key electrical and environmental characteristics include a rated voltage of 250 V, an operating temperature range of -40°C to 105°C, and an endurance rating of 8000 hours at 105°C. Status: End Of Life.

Key Features

• Capacitance & Voltage – 100 µF nominal capacitance with a rated voltage of 250 V suitable for high‑voltage power filtering and energy storage.
• Loss Characteristics – tanδ (dissipation factor) of 0.15 measured at 20°C, 120 Hz, supporting predictable AC loss behavior in design calculations.
• Ripple Current Performance – 340 mA low‑frequency ripple current at 120 Hz and 544 mA high‑frequency ripple current at 10 kHz, enabling handling of both line‑frequency and high‑frequency switching ripple.
• Leakage Current – Leakage current specified at 1100 µA, useful for standby and bias current budgeting.
• High‑Temperature Endurance – Rated for 8000 hours at 105°C, providing long life in elevated‑temperature operating environments.
• Package & Mounting – Radial, can package with φ18 × 35.5 mm dimensions and 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Series Design Intent – From the UPW series: miniature sized, low impedance and high reliability for switching power supplies (series specification).
• Polarized Construction – Polarized aluminum electrolytic capacitor for DC power applications; includes pressure relief vent per radial lead design.
• AEC‑Q200 Rating – Series rating included in product data (AEC‑Q200), supporting designs that require automotive‑grade component qualification.

Typical Applications

• Switching Power Supplies – Low impedance and defined ripple current ratings make this capacitor suitable for bulk and output filtering in switching regulators.
• Automotive Power Rails – AEC‑Q200 listing and an operating range to 105°C support use in automotive and vehicle electronics power subsystems.
• Industrial Power Electronics – High temperature endurance (8000 h at 105°C) and 250 V rating suit industrial DC‑link and filtering roles in control equipment.

Unique Advantages

• High Voltage Capability: 250 V rating enables use in higher‑voltage power rails without multiple lower‑voltage capacitors in series.
• Defined Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz allow designers to size components for both low‑ and high‑frequency ripple environments.
• Long Endurance at Elevated Temperature: 8000 hours at 105°C provides predictable life for thermally demanding applications.
• Compact, Through‑Hole Form Factor: φ18 × 35.5 mm radial can with 7.5 mm lead spacing simplifies layout and mechanical retention for through‑hole assemblies.
• Polarized, Pressure‑Relief Design: Polarized construction with a vent for reliable operation and safety in routine high‑energy use.
• Automotive‑Grade Qualification: Inclusion of AEC‑Q200 in product data supports regulated and automotive design considerations.
