UPS1E220MDD

The UPS1E220MDD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon's UPS series, designed for low-impedance filtering in switching power supplies and general-purpose electronics. It combines a compact φ5 × 11 mm can with a 25 V rated voltage and 22 µF capacitance for space-constrained power-rail and decoupling applications.

Key performance attributes include a wide operating temperature range of −55°C to 105°C, specified endurance of 2000 hours at 105°C, and measurable ripple-handling capability across low and high frequencies—making it suitable for a range of embedded and power-conversion designs.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with ±20% tolerance and a 25 V rated voltage for typical DC rail and decoupling use.
• Low-loss Performance: Tangent of loss angle (tanδ) of 0.14 measured at 20°C, 120 Hz, supporting stable impedance characteristics in power circuits.
• Ripple Current Handling: Low-frequency ripple current 27.2 mA at 120 Hz and high-frequency ripple current 160 mA at 10 kHz, providing practical ripple filtering across switching and high-frequency environments.
• Leakage & Endurance: Specified leakage current of 16.5 µA and endurance of 2000 h at 105°C under rated conditions for predictable long-term behavior.
• Wide Temperature Range: Rated for −55°C to +105°C to accommodate both cold-start and elevated operating environments.
• Compact Radial Package: φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm) in a radial-lead form factor for through-hole mounting in compact PCBs.
• Packaging Options: Supplied in bulk (no terminal forming) or bag packing to suit assembly and prototype needs.
• RoHS Compliant: Conforms to RoHS requirements as noted for the UPS series.
• Lifecycle Status: End Of Life — verify current availability before planning production designs.

Typical Applications

• Switching Power Supplies: Output filtering and bulk decoupling for compact switching regulators where low impedance and high-frequency ripple handling are required.
• Embedded Power Rails: Local decoupling on board-level DC rails in embedded systems and consumer electronics, leveraging small footprint and radial through-hole mounting.
• Power Converters and Adapters: Smoothing and ripple attenuation in isolated and non-isolated converter stages across a wide temperature range.
• Industrial Control Electronics: General-purpose energy storage and filtering in control modules that require robust temperature and endurance characteristics.

Unique Advantages

• Compact footprint: φ5 × 11 mm can offers a small physical profile for space-constrained boards without sacrificing capacitance.
• Broad temperature capability: Operates from −55°C to +105°C, enabling use in environments with large thermal variation.
• High-frequency ripple support: 160 mA rating at 10 kHz provides tangible benefit for switching-regulator output stages and high-frequency decoupling.
• Predictable endurance: 2000 hours at 105°C gives a defined lifetime metric for thermal-stressed applications and design planning.
• Through-hole robustness: Radial lead package with defined lead spacing simplifies prototyping and serviceable designs.
• Regulatory compliance: RoHS-compliant construction aligns with common environmental requirements.
