UPW1E220MDD

The UPW1E220MDD is a radial lead aluminum electrolytic capacitor from Nichicon’s UPW series, offering a miniature, low-impedance solution for compact power designs. It is optimized for switching power supplies and other space-constrained power circuits that require reliable ripple handling and temperature endurance.

Key Features

• Capacitance and Tolerance — 22 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 25 V DC rating suitable for low-voltage power rails.
• Low Loss / Low Impedance — Tangent of loss angle (tanδ) 0.14 measured at 20°C, 120 Hz, indicating low dissipation for its class.
• Ripple Current Capability — 54 mA at 120 Hz (low frequency) and 180 mA at 10 kHz (high frequency) for effective ripple filtering in switching applications.
• Leakage Current — 16.5 µA specified leakage after voltage application.
• Temperature Range & Endurance — Rated for −55°C to +105°C with an endurance rating of 2000 hours at 105°C.
• Package & Mounting — Radial lead (axial can style) with compact dimensions φ5 × 11 mm and 2.0 mm lead spacing (±0.5 mm tolerance).
• Polarized — Standard polarized aluminum electrolytic construction for DC power applications.
• AEC‑Q200 Rated — Designed to meet AEC‑Q200 qualification requirements for demanding applications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible supply options.

Typical Applications

• Switching Power Supplies — Compact decoupling and output filtering where low impedance and high-frequency ripple handling are required.
• Automotive Electronics — Suitable for automotive electronic modules that require AEC‑Q200 qualification and operation across −55°C to +105°C.
• Compact Power Modules — Through-hole radial form factor for use in small power assemblies and board-level power rail conditioning.

Unique Advantages

• Space-efficient footprint — φ5 × 11 mm size provides high capacitance in a miniature package to save PCB area.
• Effective ripple handling across frequency — Specified ripple currents at 120 Hz and 10 kHz enable reliable filtering for both low- and high-frequency switching noise.
• High-temperature endurance — 2000 hours at 105°C supports longevity in thermally demanding environments.
• Low leakage and dissipation — 16.5 µA leakage and tanδ 0.14 help minimize loss and standby power impact in DC circuits.
• Automotive-grade qualification — AEC‑Q200 rating aligns the part with automotive electronic design requirements.
• Through-hole mounting simplicity — Radial lead configuration simplifies prototyping and assembly on through-hole and mixed-technology boards.
