UPW1E221MPD

The UPW1E221MPD is a miniature aluminum electrolytic capacitor in Nichicon's UPW series designed for low impedance and high reliability. It is a radial-lead, polarized can-style capacitor specified for compact power electronics where stable filtering and ripple handling are required.

Targeted applications include switching power supplies and automotive electronics; the part combines a 220 µF capacitance at 25 V with an extended operating temperature range and AEC-Q200 qualification for high-reliability environments.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 25 V, with ±20% tolerance for design predictability.
• Low Impedance — Specified impedance of 234 mΩ, supporting effective decoupling and smoothing in power circuits.
• Ripple Current Handling — Rated ripple current of 360.8 mA at 120 Hz and 555 mA at 10 kHz, with frequency coefficients available for different operating frequencies.
• Thermal and Lifetime Performance — Operates from −55°C to +105°C and rated for 3000 hours at 105°C, enabling long-term use in elevated-temperature environments.
• High-Reliability Qualification — AEC-Q200 rated to meet automotive-grade reliability requirements.
• Package and Mounting — Compact radial-lead can package (L: 1.15 × D: 0.8 cm) with 3.5 mm lead spacing for through-hole mounting in space-constrained boards.
• Polarized Electrolytic Construction — Standard polarized aluminum electrolytic design for bulk energy storage and smoothing applications.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple-current capability make it suitable for output filtering and smoothing in compact switching regulators.
• Automotive Electronics — AEC-Q200 qualification and wide temperature range support use in automotive control modules and in-vehicle power systems.
• Space-Constrained Power Modules — Miniature can package and radial-lead form factor enable use where board space is limited but bulk capacitance is required.

Unique Advantages

• Compact form factor: Small L × D dimensions (1.15 × 0.8 cm) and radial mounting help preserve PCB real estate while providing 220 µF of capacitance.
• Measurable low impedance: 234 mΩ impedance supports improved transient response and lower voltage ripple in power rails.
• High ripple tolerance: Rated ripple currents of 360.8 mA (120 Hz) and 555 mA (10 kHz) allow reliable operation under varying switching frequencies.
• Designed for harsh environments: −55°C to +105°C operating range and 3000 hours at 105°C endurance deliver predictable lifetime in elevated-temperature applications.
• Automotive-grade reliability: AEC-Q200 rating provides traceable qualification for designs requiring automotive-level assurance.
• Through-hole robustness: Radial lead, can-style package simplifies handling, inspection and mechanical robustness in assembly.
